How to Fix Brakes on a BMX Bike
Without properly functioning breaks, a day on the BMX track can be disastrous. Watch for general wear and tear and any deterioration on your break pads. Try a few simple techniques with a screwdriver and WD-40 before heading to the bike shop. A bike mechanic is always the best option if you have little to no experience working on your bike.

Squeeze down on the brake handles and watch for movement. Cables can get caught or loose. Use a screwdriver to tighten the clamp or take it apart to untangle your cables. You may need to replace them with new cables from a BMX bike shop.

Try breaking a few times and watch the bike wheel and your brakes. If one side is catching or sticking, try some WD-40 or other lubricant to get it working. The bolts may need to be loosened on the caliper and readjusted.

Look at your wheels. They may not be aligned properly and catching the break. Take apart the nuts and bolts with a wrench and screwdriver and reset the tires appropriately.
Replace the Brake Pads

Look to see if the brake pads are worn down. You need about 1/4-inch of rubber on the pad between the tire and clamp for solid breaking.

Replace thin brake pads immediately by unscrewing nuts and bolts and pulling out the pads. Avoid replacing with universal break pads or substituting for another model. You need pads that are specifically designed for your BMX bike.

Realign your brake pads carefully and screw in the nuts and bolts. Take your bike on a test run to see how the brakes work. If they feel loose or stick, try readjusting the pads and re-tightening the bolts.

Tips & Warnings
Check to see if your bike is still under warranty before fixing it yourself. Take your bike to a BMX shop if you have never worked on your bike before.
Always wear a helmet and test drive your BMX bike around the neighborhood after a repair.
