Brakes - mechanism

  • Bolt brake calliper -1- with both guide pins -arrows- to backplate.
  • Fit cover caps.

Brakes - mechanism

  • Connect brake pad wear indicator connector -1-.

Brakes - mechanism

Note The plug connection of the brake pad wear indicator is located on the right side of the vehicle.

  • Fit the wheels.

Note After changing pads, check the brake fluid level.

WARNING

After installing 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.

Make sure that the brakes work properly before the vehicle is driven on the road.

Installation:

Caution

Before pressing piston back into cylinder with piston resetting tool, draw off brake fluid from brake fluid reservoir. Otherwise, if brake fluid has been refilled, this might leak and cause damage.

Brake fluid is toxic and should never be sucked by mouth using a flexible tube.

Before installing the new brake pads, the brake pistons have to be pulled back using the piston resetting tool - T10145- .

  • Lightly grease brake pad guide surface on the brake carrier with lithium grease G 052150 A2 .
  • If provided, peel adhesive foil off back of brake pads.
  • Insert brake pads into brake caliper.
Caution

Observe the correct installation position of the brake pads.

The arrow on the back of the brake pads must point in the direction of forward rotation of the brake disc.

Note The brake pad wear indicator wire is installed in both brake pads of the right brake calliper.

  • Slide one brake pad retaining pin -16- through brake caliper and brake pads from inside to outside.
  • Insert retaining spring -14- underneath retaining pin -16-.
  • Slide second retaining pin through brake caliper and brake pads from inside to outside. While doing so, press down retaining spring -14-.

Brakes - mechanism

WARNING

Both brake pad retaining pins must be pressed through the brake caliper and the brake pads as far as the stop so that the spring is seated at the retaining pin in the brake caliper.

  • Insert pad wear indicator wire -12- in retaining spring -14-.
  • Connect pad wear indicator wire.
  • Insert pad wear indicator wire in bracket.
  • Fit the wheels.

Note After changing pads, check the brake fluid level.
