Removing

Note:

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

• ‒ Raise vehicle.
• ‒ Remove wheels.

• ‒ → Secure brake disc with a wheel bolt.
• ‒ Unscrew both Torx bolts for the outer brake pads.

Note:

Before pressing back the piston, extract brake fluid from the brake fluid reservoir with a bleeder bottle. Otherwise brake fluid which was used to top up the brake fluid reservoir, may escape and cause damage.

• ‒ → Press piston back into brake caliper housing.
• ‒ For this purpose, insert sliding caliper with screwdriver as shown and press firmly outwards.
• ‒ First remove outer brake pad; for this purpose, use screwdriver to press brake pads off brake caliper.

• ‒ → Firmly press floating caliper in direction of arrow as far as it will go.
• ‒ Use screwdriver to carefully press brake pads out of piston and remove from brake caliper housing.

Note:

Thoroughly clean brake caliper housing before installing new brake pads.

In particular, watch for residual adhesive sheet from the outer brake pads.

Installing

• ‒ → Insert lower and upper brake pads into piston.

Note:

Take care not to damage protective caps when inserting brake pads.

• ‒ → Press floating caliper outwards as far as it will go.
• ‒ Pull protective sheet off backplates of outer brake pads.

Notes:

• ◆ The repair kit includes four self locking Torx bolts which must be installed in all cases.
• ◆ Each time after replacing the brake pads, depress the brake pedal firmly several times with vehicle stationary so that the brake pads are properly seated in their normal operating position.

• ‒ → Screw the Torx bolts from the repair set into the floating caliper and fix the brake pads in position.

• ◆ Tightening torque: 25 Nm.

• ‒ Unscrew wheel bolt from wheel hub.

Note:

When fitting on the wheels, make sure that the rim flange is not mounted onto the brake caliper.

This could otherwise press the brake pads out of their guides.

• ‒ Fit wheels and tighten to 120 Nm.
• ‒ Check brake fluid level and top up if necessary.
