The bicycle on the net, install it yourself, how to get the brake failure

1.Check the brake pads. Check if the brake pad is far away from the rear wheel, and if so, adjust the distance between the brake pad and the tire.

2.Adjust the brake line. The rear wheel of the bicycle has a brake line, check that the brake line is tightened evenly, and adjust it if it is too tight.

3.Replace the brake cable. If the brake cable breaks, a new one needs to be replaced.

4.Adjust the brake pads. If the brake pad is one in front and one behind, it will also affect the braking effect, and the brake pad needs to be adjusted to keep it in the same position.

If the above methods still do not solve the problem, it is recommended to contact the bicycle seller or a professional bicycle repair shop for further consultation and service.

Two workarounds:

First, find a place to repair the car and pay for it yourself.

Second, reflect to the seller, either resend one, or repair the brake money, if the merchant is unwilling, apply for a certain treasure, a certain east, **buy to find ** customer service, explain the situation, the customer service intervenes, or refund, or the merchant agrees to re-ship.

If the merchant is unwilling, **don't care, 12315, consumer complaints** go a wave, explain the situation, and will definitely deal with it for you. Anyway, you must fight on the basis of reason, and don't give in.

Hope it helps.

1. Adjust the brake skin

When the rear brake of the bicycle fails, check the brake skin first, sometimes the brake skin is far away from the rear wheel, the brake is naturally not easy to use, then adjust the distance between the brake skin and the tire.

2. Adjust the brake cable

There is a brake line on the rear wheel of the bicycle, you can hold the brake yourself and try it, it is very likely that the brake line is not evenly tightened, such as too tight, then there will definitely be brake failure, just adjust it.

3. Replace the brake cable

The brake line is made of high-carbon steel wrapped in a black tube, once these high-carbon steels are broken, then it is bound to directly cause brake failure, check and replace it.

4. Pay attention to adjusting the brake pad one front and one behind

This is also a cause of rear brake failure, when braking, the brake pad is close to the wheel, then the brake is almost ineffective, so as long as you adjust the brake pad, let it stay in a position.

If the brakes of the bicycle are broken, then you should repair the brakes in time and then drive on the road, which is safer, because the brake is a very safe problem.

1 The adjustment method of the ordinary front brake is as follows: loosen the brake nut with a wrench, lift the front brake fork and the front pull tube up with the left hand, so that the distance from the brake skin to the rim is only 1 mm, and then use the right hand to pull the short pull rod on the handlebar down, make the short pull rod and the front pull pipe in a straight line, tighten the brake nut, and after letting go of the left hand, the brake skin will drop 1-2 mm, so that the brake skin is about 3 mm away from the rim. 2 4 The adjustment method of the ordinary rear brake is:

First loosen the clamping nut under the frame, then tighten the adjusting nut, adjust the brake skin to about 3 mm from the rim, tighten the clamp nut, if the brake is too close to the rim, adjust in the opposite direction. If the ram, short tie rod, rear pull pipe and other parts are loose, or the tension angle of the rear crank spring is too large, and the elasticity is small, you can tighten the loose brake screw, lift the rear pull tube up with the left hand, so that the brake skin is close to the rim, and then use the right hand to pull down the short pull rod of the handlebar, so that the short pull rod and the rear pull pipe form a straight line, and then tighten the brake screw, when the rear crutch spring is loose, and can not be adjusted up when the rear pull pipe, you can tighten the nut on the long pull rod joint, pull the back crank forward, make the rear brake skin, the rear brake fork move forward, and press the rear crank spring at the same time, Finally, tighten the nut on the long tie rod joint.

When braking, the contact area between the brake pad and the rim on one side is large, and the contact area between the brake pad and the rim on the other side is small. The reasons for this failure are: (1) The front wheel or rear wheel is not aligned, the front wheel or rear wheel should be aligned, so that the distance between the front rim and the left and right fork legs is equal, so that the rear rim.

The distance between the left and right flat fork legs is equal; (2) If there is axial flutter in the rim, the axial flutter of the rim should be eliminated; (3) When the ram is misaligned, the screws on the splint should be loosened, the ram should be straightened, and the screws should be tightened; (4) If the fork is deformed, you can use a wire cutter to clamp the brake and turn to correct the deformed fork. If the brake skin is facing outward, the brake fork can be pulled inward; On the contrary, pull outward, and then adjust the position of the ram to make the left and right brake skin symmetrical. 4 43 When braking, the brake pad touches the rim one after the other and causes this failure and the way to overcome it is:

1) If the fork is not corrected, when the front fork is installed, the screws of the brake screws and the screws of the ram should be tightened, and the ram and the front fork should be straightened, and then the screws should be tightened. When the rear brake fork is straightened, the splint screw should be loosened, the brake fork should be straightened, if it is still not possible, the nut on the rear crank plate should be loosened, the rear crank plate should be rotated, and the rear crank should be straightened; (2) If the brake fork is deformed, the brake fork should be corrected, if the brake skin on the right side of the brake fork first touches the rim, the straight part of the brake skin can be pulled down to make the brake skin leave the rim, or the left straight part is pulled upwards to make the brake skin close to the rim; Conversely, the pull is in the opposite direction.

The brakes of the bicycle are broken, if you have a strong do-it-yourself ability, buy one on Pinduoduo and install it yourself.

What to do if your bike's brakes are broken? Of course, it is to go to a professional bicycle shop to repair or replace, and it is unsafe without brakes.

What should I do if the brakes of the bicycle are broken, go to a professional repair department to change the brakes.

It's very simple, just change the brakes, and it's not much money to go to this place to repair the bike.

If the brake of the bicycle is broken, it should be sent to the bicycle repair shop to replace one, otherwise it will be very dangerous to ride, and without the brake, the safety is not guaranteed.

Check whether the brake pads and brake discs are normal, check the brake fluid, check the brake vacuum booster and vacuum tube, it is also possible that the braking time is too long, resulting in a decrease in the friction coefficient, which will make the brakes insensitive. If you're not too professional, it's best to go to a repair shop. Hope to adopt!

Taiwan Yanhao's entry-level oil disc, the quality is OK, about 300 before, and now about 280 sets.

There are several reasons why the oil disc brakes do not work:

Clause. First, if the order piece is seriously worn and needs to be replaced, you can use a flashlight to shine it to see if the thickness of the order piece is sufficient;

Clause. Second, it is a bicycle riding on a rainy day, the disc is stained with oil, to judge whether there is oil stain, whether you make a loud sound when braking can be judged, if so, there is a very loud sound, then you can take the use of carbon drink rinse, or a long distance downhill pinch the brake to heat the method to evaporate the oil, and another is to remove the piece and boil the disc in water for 20 minutes.

Clause. Third, the oil disc leakage, this directly judge whether the feel has strength can be judged, observe whether there is oil stains, but generally this situation is rare.

The mountain bike brakes failed and needed to be repaired.

1. Is there a problem with the V brake, changing the brake pad, and overhauling other parts;

2. Disc brake, in exchange for the order piece, whether there is any problem with overhauling other parts;

If you don't know how to do it yourself, go to the car shop to repair it, and a professional master will repair it.

The brake pads of the handbrake are too badly worn, and it is good to replace the brake pads appropriately.

The professional name of the handbrake is the auxiliary brake, which is different from the principle of the brake, which is connected to the rear brake shoe by a steel wire cable to brake the car. Long-term use of the handbrake will cause plastic deformation of the wire, and since this deformation is irreversible, long-term use will reduce the utility, and the travel of the handbrake will also increase.

The handbrake is complemented by a recovery spring. When the handbrake is pulled up, the spring is elongated; The handbrake is released, and the spring returns to its original length. When the handbrake is used for a long time, the spring will also deform accordingly.

It is the brake that is loose, and you can get it yourself by finding the right position.

Organic brake pads are made of mixed fiberglass, etc., without any metal powder. Yes, you can have strong braking forces, but in hot and humid conditions, the force is degraded more drastically than brake pads with metal-based formulations.

The advantage is that this kind of brake pad does not conduct heat, so there is no need to worry about the thermal expansion effect of oil, so it is ideal for use in closed hydraulic systems. and metal brake pads.

The main problem of disc brakes not braking:

1. Disc brake oil, the principle of disc brake is that the brake pad (to the plate) and the disc friction brake, once the oil, there is bound to be no friction, can not brake the car, but after the oil will be very difficult to hear (a big whine, the car will tremble), if this is the case, then you can only change the disc and the ring, if you want to save money, only change the grain, the disc can be washed with soap and water in the water.

2. There are too many stains on the disc. If there is mud on the disc, or the dry muddy water is stained on the disc, it will also affect the brake effect, so the disc should be cleaned in time, this situation is much simpler, just take water to rinse the disc and brake pads, and wipe the sewage with a dry rag.

1.The bicycle brakes are not working, first of all, we should check whether there is a problem with some small equipment and parts in the brake, if it is to make the pads wear.

2.After inspection, if the piece is worn, we can push the bike to the bicycle repair station for repair. Generally speaking, change the one to make the film**.

3.Poor brakes can also be caused by overuse of the brake wires in your bike, which can be caused by overstretching.

What is the Ryo Piece.

Ringing pads are also called brake pads.

In the braking system of bicycles, brake pads are the most critical safety parts, and all brake effects are decisive for brake pads, so good brake pads are the protectors of people and bicycles.

Hello, I am your exclusive elite technician of the Shed Wide Car Master, I wish you a happy life and a prosperous Year of the Tiger. We promise to be attentive, careful and attentive to answer your car problems, and find solutions and solutions to the corresponding problems for you! The brake chain is not bright, and it is also possible that the brake wire in your bike is overused, which is caused by overstretching.

I checked because there was a problem with the bike's brake wires, which we could manually adjust with pliers or other tools. Tighten the connection between the brake lever and the brake cable a little before Qing. You can put some oil on the wire rope at the handlebar junction and let him move it, which is usually caused by stagnation.

If the bicycle brakes are not working, you can adjust it like this:

Tools: Aristocratic Bike x3, Hex Wrench.

1. Hold the brake lever and check the position of the pad, the left and right brake pads must be in contact with the front wheel rim at the same time. It must be centered on the rim width so that the top and bottom clearances of the mat are equal. If the mat is too high or too low, it is in contact with the rubber part or spokes of the tire.

Hold the brake lever and bend down from the mat to check the brake pads.

2. Use a hex wrench to loosen the bolts on the brake pads, turn the hex wrench counterclockwise, and loosen the bolts that fix the brake pads. If it comes loose, the brake pads will come loose from the brake pad holder, so be careful.

3. Move the brake pads up and down to adjust the position After the bolt is loose, it can be easily moved. In the pad bracket, move the pad up and down to adjust its position so that it is in the center of the rim.

4. Fix the brake pads again with a hex wrench, turn the hex wrench clockwise, and then tighten the bolts. Check that the brake pads are centered and readjust if necessary.

5. Adjust the tension of the moving line, pull the left and right brake levers, check the tension of the wire, and when pulling the brake levers, the distance between the rod and the handle is about 4 cm is the appropriate tension. When the skater is open with the handle, the brake line is extended.

6. Release the barrel adjuster and adjust the brake line, if the brake line is slightly stretched, it can be easily adjusted by loosening the barrel adjuster. The barrel adjuster is connected to the connecting part of the brake lever and the wire.

7. Loosen the brake wire bolt of the caliper, the caliper is the main part of the brake structure, and is equipped with brake pads. The brake line is a thin line that extends from the caliper. Find the bolt that holds the brake line in place, turn it counterclockwise a few times with a hex wrench, and loosen it a little.

8. Pull the brake wire outward, and adjust the tension bolt to loosen, so it is easy to pull the wire. Secure the wire with a pin and then with your fingers. At this point, make sure the brake pads are tightened on the front rim.

When I bend the handle, I tighten it and feel a bit of resistance. But be careful not to tighten and bend the steering wheel.

9. Tighten the brake wire bolt of the caliper, turn the hex wrench clockwise two to three times, and then tighten it firmly. Once tightened, make sure the wires are properly secured.

10. Pull the brake lever to check the tension of the brake line. When pulling the rod, the spacing of about 4 cm between the lever and the handle handle is normal tension.
