Disc Brake PaD aDvancement anD rotor BeD-in ProceDure PRoDuct InstAllAtIon uPDAte Avid disc brakes achieve the best ‘out of box’ performance when both the Pad Advancement and Disc Brake Pad and Rotor Bed-in procedures are completed during the initial brake installation and setup. By performing these two procedures the rider will experience the best braking performance possible and prevent concerns related to improper set up later. Pad Advancement Procedure Avid disc brakes may ship with a pad spacer/bleed block installed in the caliper to prevent improper advancement of the pistons and pads during shipping. After removing a pad spacer, bleed block, or rotor and wheel, it may be necessary to perform the pad advancement procedure. Squeezing the brake lever once is not sufficient to properly advance the pads. Improper pad advancement can cause the brake lever to pull to the handlebar during installation which can be misdiagnosed as a poor brake bleed or other problem. Be sure to complete the entire disc brake pad advancement procedure. 1. If your brake is equipped with the contact adjustment feature on the lever body, turn the contact adjust barrel or screw in the opposite direction of the arrow until it stops. 2. Remove the pad spacer/bleed block or rotor/wheel. 3. Slowly squeeze the brake lever several times until the pads are approximately 1 mm apart - about the thickness of a zip tie, and then release the brake lever. Repeat as necessary. 4. Insert the pad spacer/bleed block into the caliper. A moderate amount of force will be required to spread the pads outward to the correct position. 5. Install the wheel/rotor. Squeeze the brake lever several times; the brake should feel firm. 6. Align the caliper as needed. Adjust the reach and pad contact point to the rider’s preference. If the brake pads are not advancing evenly, push the pistons back into the caliper bor
