Removing and installing brake pads/linings

Special tools and workshop equipment required

  • Piston compressing tool - T20146-
  • Torque wrench - V.A.G 1331-

3.1.1 Removing

Mark brake pads when removing if they are to be reused. Fit in same position when installing, or braking will be uneven.

  • Remove wheels.
  • Push handbrake lever in direction of -arrow- and unhook handbrake cable from handbrake lever.
  • Compress both locking lugs -arrows- together, then pull handbrake cable out of bracket on brake caliper.
  • Remove securing bolts from brake caliper, to do this counterhold on guide pins.
  • Remove brake caliper and secure with wire so that weight of brake caliper does not strain or damage brake hose.
  • Remove brake pads.

Cleaning:

  • Thoroughly clean contact surface for brake pads on backplate and remove corrosion.
  • Clean brake caliper, in particular the bonding surface for the brake pad. It must be free of adhesive and grease residues.

Use only methylated spirits for cleaning the brake caliper housing.

3.1.2 Installing

Before turning piston back, draw off brake fluid from reservoir. Otherwise, particularly if reservoir has been topped up, fluid will overflow and cause damage.

  • Turn piston to right into brake caliper with piston resetting appliance - T20146-; do not damage protective cap.
  • Thoroughly clean contact surfaces -arrows- of brake pads.
  • Pull protective foil off brake pad backplate.
  • Insert brake pads into brake carrier.
  • Screw brake caliper to brake carrier with new securing bolts, counter-holding at guide pin.
  • The repair kit includes 4 self-locking hexagon bolts which must always be installed.
  • Push handbrake cable into bracket on brake caliper until both locking lugs -arrows- engage.
  • Push handbrake lever in direction of -arrow- and attach handbrake cable onto handbrake lever.
  • Fit wheels.

Specified torque of wheel bolts ⇒ Running gear, axles, steering; Rep. gr. 44; Specified torques of wheel bolts.

Specified torque:
