How to Adjust Mechanical Disc Brakes on a Mountain Bike: A Step-by-Step Guide
To adjust mechanical disc brakes on a mountain bike, start by squeezing the brake lever and examining how far the brake pads move in towards the rotor. If they don’t come close enough, use the adjustment knob near the brake lever to adjust the cable tension until the desired gap is achieved. Next, adjust the caliper alignment by using a wrench to loosen the bolts that secure the brake caliper to the frame or fork, and then gently wiggle the caliper until it aligns with the rotor. Tighten the bolts back up and test the brakes again to ensure proper adjustment.
