How To Center Road Brake Calipers | by SRAM
This short explainer video by SRAM will help you get your brakes aligned and sorted, in a jiffy.
If your brake rotor is rubbing, it may require centering. Start by using a T25 Torx wrench to loosen the caliper bolts. Lightly squeeze the brake lever three times to advance the brake pads toward the rotor, then keep the lever pulled to hold the caliper in a centered position. While maintaining pressure on the lever, tighten the caliper bolts to 5 Nm. Release the lever and check that the brake pads sit evenly on both sides of the rotor. If they’re not perfectly centered, repeat the process and make minor hand adjustments to the caliper as needed, as demonstrated in this video by SRAM.
