4 Cylinder Cars (Water-Cooled)

FIGURE 1:

Color coding and semicircular cutouts (Fig. 1) in the area of the retaining pin holes identify asbestos-free brake pads.
Arrows show location of semicircular cutouts.

FIGURE 2:

WARNING:

Mixed installation of brake pads (with and without asbestos) on a vehicle is not permissible. When installing asbestos-free brake pads on cars prior to the 1989 model year, both front and rear pads must be replaced.
944 Turbo and Turbo S

944 Turbo S model year 1988 and 944 Turbo model year 1989 have vibration dampers installed on the front calipers between the pistons and the brake pads. Brake pad thickness is reduced to 17.5 mm (was 18.2 mm). When replacing brake pads, the vibration dampers must also be replaced.

FIGURE 3:

NOTE:

Early 1988 Turbo S vehicles have asbestosfree brake pads with sintered metal plugs (Part Number 928 351 939 03) installed on the front axle up to VIN 95JN151487 (Fig. 3). Existing stock of pads may be used up. Vibration dampers cannot be installed with these pads. Pads with and without plugs must not be mixed on a vehicle.

FIGURE 4:

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. 4).
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 these brake linings expand more with heat than brake linings with asbestos. Refer to Workshop Manual 944, Volume III, page 46-6 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 the other direction until the wheel can be turned freely. Turn star nut an additional two notches.
