If you ask a master to adjust it, it may be twenty or thirty yuan, maybe some masters won't take money, after all, it's just a little thing.

How much does it cost to buy a shift bicycle disc brake friction online, and you won't find a maintenance master? I don't know about this, because the charges in each place are different, maybe a few dollars, or a dozen or so yuan.

If you just adjust it and don't replace the parts, it won't cost much, and if it's better, you may not need to charge money.

BicyclesDisc brakesThe piece has a friction sound reason:

1. The disc brake is deformed.

This situation usually occurs in the summer, especially when the downhill is in a state of braking for a long time, which will lead to deformation.

2. The wheel set is not installed properly.

In this case, you can hold the handlebars upright and observe if the wheels align with the frame. If the front direction of the wheel is to the right and the rear to the left, this is the reason.

3. The piece is seriously worn.

After a long period of riding, the wear and tear of the liner will become more and more serious, which will lead to abnormal noise.

Mountain bikesHow disc brakes work:

It is a steel disc fixed on the hub through a clamp, so as to achieve the purpose of braking. While working, the clamp clamps the steel platter, increasing the resistance by increasing friction.

The environment of mountain bikes is usually more complicated, so the damage to the bike is also relatively large, so the bike owner often checks and repairs.

Resulting in discsHowlingThe reasons are generally as follows:

1. The disc or the piece is sticky with dirt such as water or mud, and the surface of the disc will produce uneven impurities.

2. There is also an irregular use method and the lack of manuscripts will leave different shades on the disc, the length is very irregular scratches, plus a little dust or something will exacerbate the roaring pure scream, generally vigorously brake, the fierce brake is easy to scratch irregular traces on the disc, so the use of brakes to slow brake, do not point brake, brake, brake as slowly as possible, not to say that the whistling is not good, the disc is not good, this is a normal phenomenon.

3. If you really can't stand it, you can brake the disc.

Remove it, clean the disc and liner with brake cleaner, and take care to protect your hands so that they don't get scratched by the disc. Then sand the disc with sandpaper, clockwise.

Grinding, according to the texture of the disc (according to the degree of grinding marks, generally 10 circles are about the same, according to the surface flatness of the disc).

By the way, slightly polish the piece and smooth it, you don't need to grind too much! Just wipe it dry and install it back at the end.

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.

Mechanical, hydraulic:

Mechanical disc brakes, relying on the pull of the brake line to make the brake pads in the caliper rub and clamp the disc, resulting in a braking effect. Hydraulic type, with oil as the medium, pulling the brake lever is to make the piston inside to compress the oil, and the pressure is straight from the oil pipe to the caliper, so as to push the piston in the caliper and drive the brake pad to clamp the disc.

Mechanical disc brakes have the convenience of compatibility, and the general V-shaped brake lever can be universal. The brake lever, oil pipe and caliper of hydraulic disc brakes are a complete set of products, and naturally there is no common intersection with traditional cable-actuated brakes.

Hello, I'm also a car fan, I currently have a car, the front and rear are disc brakes, to explain to you the main problem of disc brakes can't brake:

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.

These two are the main problems, if it is not these problems, it may also be that the brake line is loose and the goods are deelastic, it is not these problems, then you can only change the full set of disc brakes, I hope you will please the difficulties as soon as possible, I wish you a happy ride.

1. First loosen the disc brake screws of the rear wheel with a screwdriver.

2. Then lift the disc brake arm up.

3. Then pull the wire downward, and it will be loose after adjusting because the wire is loose.

4. Then tighten the screws.

5. At this time, even if it is completed, you can push the rear wheel down and try the effect of tensioning.
