Removing

Note:

Mark brake pads to be reused on removal. Reinstall in their original position to prevent uneven braking!

• ‒ Raise vehicle.
• ‒ Remove wheels.

• ‒ → Lever off brake pad retaining spring from brake caliper housing with a screwdriver and remove.

• ‒ → Remove protective caps.

• ‒ → Unscrew both guide pins and remove from brake caliper.
• ‒ Remove brake caliper housing and lay to one side so that the weight of the brake caliper does not stress or damage the brake hose.
• ‒ Remove brake pads from brake caliper housing or from brake carrier.

Installing

• ‒ → Press back piston.

Note:

Before inserting new brake pads, press piston back into the cylinder with resetting tool. Before pressing the piston back, draw off brake fluid from the reservoir with a bleeder bottle. Otherwise brake fluid which was used to top up the brake fluid reservoir, may escape and cause damage.

• ‒ Install brake pad with retaining spring into brake caliper housing (piston).

Note:

The inner pad (with expansion spring) has an arrow. The arrow should point in the direction of rotation of the brake disc when travelling forwards. If installed incorrectly this may cause noise problems.

• ‒ Detach protective sheet on backing plate of outer brake pad.
• ‒ Fit outer brake pad onto brake carrier.
• ‒ Secure brake caliper housing to brake carrier with both guide pins to 25 Nm.
• ‒ Fit both protective caps.
• ‒ Insert retaining spring into brake caliper housing.

Notes:

• ◆ After inserting the retaining spring into the two holes, press it under the brake carrier. If incorrectly installed, it is not possible to adjust the wear of the outer pad, and the pedal travel will be increased as a result.

After replacing the brake pads, depress pedal firmly several times with the vehicle stationary, so that the brake pads are properly seated in their normal operating position.

• ‒ Check brake fluid level and top up if necessary.
