8 Cylinder Cars

FIGURE 6:

Color coding and semicircular cutouts, (Fig. 6) in the area of the retaining pin holes identify asbestos-free brake pads.
Note: Asbestos-free pads for fist-calipers installed on the front axle model year 1980 from VIN 92A080750 through model year 1985 do not have semicircular cutouts. Refer to color marking for identification.

FIGURE 7:

Mixed Installation of brake pads (with and without asbestos) on a vehicle is not permissible. When installing asbestos-free brake pads on cars before 1989 model year both front and rear pads must be replaced.

Vibration dampers (Fig. 7), must be installed on cars from model year 1986 (four piston calipers) on the front calipers between the pistons and the brake pads. Brake pad thickness has been reduced from 18.2 to 17.5 mm. When replacing brake pads, the vibration dampers must be replaced also.
Note: Some early 1989 production cars received one-piece vibration dampers. In case of noisy brakes, two-piece vibration dampers should be installed.

FIGURE 8:

Very Important

Clean seating and guide surface of brake caliper with mineral spirits before installing vibration dampers and pads. Lubricants or grease must not be used in conjunction with vibration dampers. A light coat of sliding lubricant (Optimoly HT Part Number 000 043 004 00) may be applied on the guide surface of the pad carrier plate (Fig. 8).
Adjusting Parking Brake with Asbestos-Free Brake Linings. (standard equipment from model year 1987)

Make sure asbestos-free brake linings do not contact the brake disc when turning the wheel since asbestos-free brake linings expand more with heat than brake linings with asbestos. Refer to Workshop Manual, Volume IV, page 46-21 for hand brake adjustment and update step 4 as follows:

Insert screwdriver through hole in brake disc and adjust star nut until it is no longer possible to turn the wheel. Then turn star nut in other direction until the wheel can be turned easily.

Turn star nut an additional two notches.
