Disc Pads: Installation

  1. Using a cylinder brush, clean guide surface and support surface in caliper. Siphon sufficient fluid from master cylinder reservoir to prevent overflowing. Press pistons to bottom of bores.
  2. On rear calipers, ensure machined position of piston face makes a 20° angle with caliper wall. See Fig 1 . Rotate piston with Piston Rotator (341050), if necessary.
  3. On front calipers, replace mounting bolts and install disc pads. Be careful not to damage dust cover on brake piston when assembling. Check position of springs. After installation, depress brake pedal several times to seat pads.
