NOTE: TECHNICAL INFORMATION
During work on the rear brake, it must be ensured that the button for the electromechanical parking brake cannot be pressed.

NOTE: TECHNICAL INFORMATION
General information on changing the brake pads:
For vehicles older than 48 months it is recommended to replace the retaining spring or expanding spring.
The brake pad wear sensor must be replaced once it has been removed because the brake pad wear sensor loses its retention capability in the brake pad.
A CBS reset must be done after every brake pad exchange:
A CBS reset in the vehicle is possible in the event of a partially ground down brake pad wear sensor. The CBS display in the Central Information Display (CID) is active.
In the event of a brake pad wear sensor that is not partially ground down, a CBS reset is only possible with the diagnostic system. No CBS display in the Central Information Display (CID).
If adhesive bonded brake pads are installed, the brake pads must be replaced after releasing the adhesive bond!

NOTE: TECHNICAL INFORMATION
To prevent damage to the surface coating: With floating calipers on the brake caliper mounting bracket or with fixed calipers in the brake caliper housing, do not clean the contact surfaces for the brake pads to the extent that it is possible.
Clean the contact surfaces with brake cleaner (BMW part number 83 19 2 154 780). Next, apply a thin coat of brake pad paste (BMW part number 83 19 2 158 851 for 3g, or 83 192 158 852 for 100 g).
Spread brake pad paste on the marked surfaces with a brush.
For additional information see: GUIDELINE FOR APPLYING BRAKE PAD PASTE ON BRAKE PADS AND BRAKE ANCHOR PLATE .
