Mountain bike disc brake to V brake, how to change ordinary mountain bike V brake to disc brake

Yes, but it doesn't feel safe...It should be the rear V-brake and the front disc brake.

It depends on whether there is a reserved hole on your fork, your front wheel group support is not supported, generally if you buy a whole vehicle, you have not considered compatibility, and the fork and front wheel set must be replaced.

Look at your bicycle for a few hundred dollars, no need to change it, and spend energy.

When changing the disc brake, you need to replace the fork and wrist set suitable for the disc brake, the specific steps are as follows:

1. Ordinary mountain bikes are shown in the figure below, this fork is a low-grade model that is only suitable for V-brakes.

2. The old fork is a special-shaped square tube, which is not easy to match with a disc brake conversion seat, and the fork opening space is not enough.

3. Remove the head tube and measure the size, the outer diameter of the upper tube is about millimeters.

4. Find suitable products online and place an order to buy: disc brake seat, disc brake pad (the seller sends screws and brake pipelines), shock-absorbing fork, and a front wheel group.

5. Unpacking after arrival, it is the following parts.

6. Disassemble the wrist group first, try to install it on the new fork, and confirm that it can be installed normally.

7. Officially disassemble the old fork.

8. As shown in the figure below, knock down the lower wrist seat of the wrist group with a hammer and a screwdriver.

9. The lower wrist seat is more difficult to disassemble, so it is recommended to buy a fork and buy the wrist group by the way.

10. Install the new fork head tube and pay attention to the cordon.

11. Adding gaskets can solve the problem of disc brake deviation and disc rubbing.

12. After the disc brake is installed, the rotor and the front hub are not integrated and can be spun out.

13. The old screws of the fender cannot be installed, remember to buy a fork and ask for a new fender screw.

14. The whole picture of the mountain bike with shock absorption + front disc brake, the disc brake installation is completed.

There is a tension screw on the left and right legs of the V brake to adjust the tension of the brake leg, the tension force that is too loose will cause one side to stick to the rim, use a screwdriver to adjust the tension screw to try, clockwise pants leakage, counterclockwise loose, but first of all, adjust the tightness of the pure leakage of the brake line key.

The V-brake adjustment method of mountain bike is as follows:

1. Pull the line: Twist the driving nut on the brake handle to the tightest (turn it clockwise to the end), and then prepare to pull the line. Thread the thread first and pre-tighten it on the fixing screws. Then leave a 5mm gap between the brake pad and the rim and lock the fastening screws.

2. Adjust the stroke of the two brake arms to be consistent

Take off two 1 cents. Pinch the brake lever with your hand and observe the stroke of the two brake arms. The goal of the adjustment is to make the travel of both brake arms the same as possible.

There is a tension screw on each brake arm, and the size of the tension of the brake arm can be adjusted by using a Phillips screwdriver (that is, the size of the angle to the outward), clockwise to increase the tension, increase the angle of tension, and vice versa.

By adjusting the tension screws on both sides repeatedly, the stroke of the brake arms on both sides is basically the same. Some people will encounter such a problem, your tension screw is screwed to the end, but there is a side of the brake arm that the opening angle is not large enough to reduce the opening angle of the other side to balance the two sides, and there is also a local method that works: take out the spring in the brake arm on the side where the angle is not enough, and break it directly with a vise.

3. Adjustment of brake stroke: the adjustment of the stroke can be adjusted by the stroke nut on the brake handle, and the counterclockwise rotation is to reduce the brake stroke, and the opposite is to increase the god button. Adjust to your preferred comfort. Remember to tighten clockwise after adjusting.
