34 11 000 Removing and installing/replacing brake pads on both front disc brakes (Countryman 2017-2023, except PHEV)

Special tools required  :

• 34 1 050
• 34 1 280 
• 2 352 960 .

Attention! 

• Do not mechanically clean the guide surfaces for brake pads to prevent damage to the surface coating. Clean the guide surfaces using brake cleaner, BMW part number 83 19 2154 780. Carefully clean highly contaminated guide surfaces with a suitable tool (e.g. brass wire brush, nylon brush). Then thinly coat with brake pad paste BMW 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! 

  Observe REGULATION ON APPLYING BRAKE PAD PASTE TO BRAKE PADS AND BRAKE ANCHOR PLATES !

• 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)  .
• A CBS reset must be done after every brake pad exchange  .
  • With a sanded brake pad wear sensor (display in CBS menu): CBS reset possible in vehicle.
  • With a non  -sanded brake pad wear sensor: CBS reset only possible via diagnostic system.

Preliminary work needed  :

• Remove front WHEELS .

Installation  :

Attention! 

New brake pads may only be installed if the brake disk thickness is greater than the minimum brake disc thickness.

Attention! 

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 the brake pads and pistons back using a special tool 2 352 960 .

Attention! 

When pressing back the pistons:

• Observe the brake fluid level in the expansion tank, overflowing brake fluid will damage the paintwork.
