Well-adjusted bike brakes not only instill a certain amount of confidence in the cyclist, but also serve as a guarantee of his safety. Therefore, most often the adjustment, and even more so, the installation of the brakes is done by professionals. For those who like to do everything with their own hands, instructions to help.
Instructions
Step 1
It is worth replacing the pads if their surface is erased to the level of the groove for the outflow of dirt. This means that the outer surface of the pad becomes extremely flat. If you observe this sight only from one side of the block, then this is the result of its incorrect installation. In this case, they also need to be replaced. To do this, you need to open the brake pads and remove from the groove the arcuate tip of the metal jacket, the tip from which the cable comes out. If you are installing new pads, it is necessary, using the instructions, to consistently fasten all washers and gaskets. It is best if you write down the sequence of their original position before removing the old pads. The main thing is not to mix them up.
Step 2
Cartridge pads are the easiest to change. These pads are made of metal, so you only need to replace the rubber pad. Handle the cotter pin with care as it is not always supplied with pads. Replace the linings and fix them with the cotter pin. The main thing is not to confuse them in places, otherwise the fastening will fail.
Step 3
After this procedure, the brakes need to be adjusted. The principle of operation on rim brakes is easy to understand - these are two brake pads that are located opposite each other and between which the wheel rim is located. When you press the brake lever, the rim is compressed by the pads, and the wheel brakes. The mechanism works with the help of a cable pull.
Step 4
In order to ensure the smooth operation of the brakes, it is necessary to monitor the condition of the cable. If there are breaks or the braid has unraveled at some interval, the cable must be urgently replaced. You also need to monitor the free movement of the cable in the shirt.
Step 5
The basic principle for proper operation of a bicycle's brakes is that the pads are properly pressed against the rim. Adjustment of this correct pad position should be done with the fastening nuts on the pad axle using a set of aluminum spacers. This set allows you to fix the pads at the desired angle. In order to do this, it is necessary to loosen the fastening of the nut and compress the brake with great effort. Position the pads so that their surfaces touch the rim completely, without touching the tires. In this position, tighten the nuts without moving the pads. For standard type pads, it is advisable to press the rear to the rim first.
