REQUIRED TOOLS
Allen wrench to size
STEP 1
Check the brake pads. The first thing you need to know is that if the brake pads are too worn the brake work inefficiently. There should be at least a quarter of an inch of rubber between the clamp and the wheel when the clamp is engaged to brake the bicycle.
If the shoes are worn, replace them.
In braking conditions, the two brake pads must attach to the circle at the same time, must not be too low (in vacuum) or too high (touch the tire) but perfectly aligned with the wheel rim. If not, your brakes may not give the best power and can be dangerous if the bike does not brake properly.
STEP 2
Check the cables.
On the brake lever on the front of the handlebars of the bike, you can if it is not already, tighten all the power of the lever, turning the cone or washer (plastic or metal), this will prevent your brakes to give trouble the outputs.
STEP 3
Make sure that the clamp is closed when the cable pulls on it or press the brake lever and watch the clamp close and open. If the cable to the brake lever moves, but in the end it does not clamp, the cable may be broken inside the sheath, and the entire cable assembly must be replaced.
STEP 4
If the pads move, tighten with an Allen key to fit the pad to the brake mechanism.
With the help of a wrench, you can refocus, swivel, raise or lower it to make the brake pad that will stick perfectly to the rim when braking.
It must be well aligned and every part of the brake pad should touch the rim without touching the tire will be in a vacuum.
Attention: Test the brakes after each processing, pedaling slowly and trying to curb
