IMPORTANT:

Do not mechanically clean the guide surfaces for brake pads to prevent damage to the surface coating. Clean the guide surfaces using brake cleaner, part number 83 19 2 154 780. Carefully clean severely soiled guide surfaces with a suitable tool (e.g. brass wire brush, nylon brush). Then thinly coat with brake pad paste, part number 83 19 2 158 851 (3 gr.) or 83 19 2 158 852 (100 gr.).
Spread brake pad paste onto the marked surfaces using a brush!
Retaining pins and expanding spring: For vehicles older than 48 months it is recommended to replace the retaining spring.
Brake pad wear sensor: After removal it must be replaced (brake pad wear sensor loses its retention capability in the break pad).
It is imperative to reset the CBS after each brake pad exchange!
- With a sanded brake pad wear sensor (display in the CBS menu): CBS reset in the car is possible.
- With a brake pad wear sensor that is not sanded: A CBS reset is only possible with the diagnosis system.

IMPORTANT:

Brake pad wear sensor: After removal it must be replaced (brake pad wear sensor loses its retention capability in the break pad).
Retaining pins and expanding spring: For vehicles older than 48 months, it is recommended to replace the retaining spring.

So as not to damage the surface coating, if possible do not mechanically clean the guide surfaces for the brake pads on the brake caliper mounting bracket. Clean with brake cleaner, part number 83 19 2 154 780 and thinly coat with brake pad paste, part number 83 19 2 158 851 (3 gr.) or 83 19 2 158 852 (100 gr.).

Remove the brake pads (1) in direction of arrow.

IMPORTANT:

The brake pads are bonded with claw plates!

If the claw plates remain in the brake piston, they must be removed from the brake pistons!

Preparation for installation:

Check minimum brake disc thickness:

Position special tool 34 1 280 at three measuring points in area (1) and measure.
Compare measuring result and lowest value with SETPOINT VALUE .

IMPORTANT:

If new brake pads are mounted on a brake disc, the following must be observed:

Bevel edges in the area (1) slightly (dimension A must not exceed maximum 1 mm).

These procedures applies for all the following described brake systems.

Press brake piston fully back with special tool 34 1 050.

IMPORTANT:

When pressing piston back, note brake fluid level in expansion tank.

Overflowing brake fluid will damage the paintwork.

NOTE: After completing repair work:

Fully depress brake pedal several times so that brake pads contact brake discs.
When installing new brake pads at front and rear axles, the brake fluid level must be brought up to the "maximum" mark.
Read and comply with notes on BREAKING IN NEW BRAKE DISCS/BRAKE PADS .

In order to ensure a complete bonding of the claw plates with the brake pads, the following instruction must be strictly adhered to:

Strongly press the brake pedal and hold it for at least 1 min!
