General Information
The brake system is one of the most important safety systems on any motor vehicle. It is therefore essential to act with
utmost care when working on the brake system and to follow the instructions below.
General:
-
Ensure cleanliness and only use rags which do not lose lint.
-
Wash away or vacuum up brake dust, do not clear it away using compressed air. This dust is a health hazard.
-
Ensure that no oils or grease enter the brake system: these substances would cause complete failure of the entire
brake system.
-
When cleaning brake components with brake cleaner (refer to BMW Parts Service), do not allow brake cleaner to
get into the brake system.
-
Even the most minute traces of brake cleaner must be avoided.
Brake fluid:
-
Replace brake fluid at least every two years.
-
Never re-use drained brake fluid.
-
Always use BMW-approved brake fluid, refer to BMW Service Operating Fluids.
-
Always dispose of brake fluid in approved receptacles, refer to BMW Service Workshop Planning documentation.
-
Do not allow brake fluid to drain into drain pipes, into the outside environment or into unsuitable facilities. This
would create the risk of groundwater contamination since brake fluid is classed as a fluid that is hazardous to
water.
-
Do not allow brake fluid to come into contact with paintwork as this will destroy the paint.
-
Brake fluid must not be allowed to remain on bare skin too long in order to avoid skin problems. Wash skin coated
with brake fluid with water and soap.
-
If brake fluid makes contact with eyes, immediately flush with large quantity of clean water and visit eye doctor.
Wheel brakes:
-
Brake linings:
Brake linings must be replaced when the warning threshold of the brake lining wear indicator is reached.
Refer to Technical Data.
Brake linings must always be replaced on both sides of any axle.
The friction surfaces of the brake linings must not come into contact with oils or greases. The brake linings must
be replaced if they are fouled by such substances.
In the case of rotation-dependent brake linings, make sure the arrow marking points in the direction of rotation of
the brake disk for when the vehicle is moving forward. Brake linings with left/right markings must be fitted on the
relevant side of the vehicle.
One-sided angled areas on the brake linings must be located on the disk contact side of the brake caliper for when
the vehicle is moving forward.
-
Brake discs:
Brake disks must not be scored or cracked. Furthermore, minimum brake disk thickness, disk runout, parallelism
and surface roughness of the friction surfaces must not exceed or drop below the permitted values.
