Portable bike stands are sold at most sporting goods stores. They typically cost between $35–50 USD.
The caliper looks like a small box about 3 inches (7. 6 cm) long that sandwiches the rotor. The caliper is the mechanical device that puts pressure on the rotor and slows down your bicycle.
On some older styles of bike, you may need to tighten the wheel in the drop house manually with an Allen wrench.
If you do get a cut, stop and wash it with soap. Bandage the small wound before you finish adjusting the brakes.
It’s possible that the disc brakes are too tight on only 1 wheel. In this case, you will not need to tighten the brake on your other wheel.
The right-hand brake lever controls the rear brake and the left-hand brake lever controls the front brake.
If you need to work on both the front and rear brakes at the same time, have a friend hold the brake levers while you work on the calipers.
If the disc brakes no longer rub, you’ve adjusted them successfully!
Again test the brakes by spinning the wheel and listening for the sound of rubbing brakes.
Not all bikes with mechanical disc brakes have a set screw on the caliper. If yours doesn’t, you can skip this step.
In some cases, bikes with mechanical disc brakes may not have an adjustment dial on the side of the caliper. In this case, there will be a hex bolt on the caliper that fills the same function.
Most rotors aren’t perfectly flat, so don’t worry if you see a small amount of wobble as the rotor spins.
The right-hand brake lever works the rear brake, and the left-hand brake lever works the front brake.
Once you’ve tightened the bolts, the bike should be ready to ride!
