How to Easily Change Your Mountain Bike’s Disc Brake Pads
To change mountain bike disc brake pads, start by removing the wheel and unplugging the brake caliper. Then, remove the retaining pin or bolt and slide out the old brake pads. Install the new brake pads into the caliper and reattach the retaining pin or bolt. Finally, reset the brake caliper by squeezing the brake lever a few times and check the alignment of the brake rotor and pads.
