Service Recommendations


Application: Saab 900 Models, M79-87 Saab 99 Models, M75-80


The primary brake pad recommendation for 1975-1987 99 and 900 front brakes has been changed to a four pad set that are chamfered, Delco DM 121 composition. These pads provide the best available combination of pad/disc wear and performance characteristics.

Note the following important points regarding these pads:


^ Because they are chamfered for use on both sides of the caliper, these pads are NOT equivalent to the two-pad set of DM121 brake pads (91 02 690). The two-pad, unchamfered DM121 set is designed ONLY for the outside of the disc, together with the Textar T474 pads on the inboard side.

^ They must not be used for cars with brake drag complaints. If the car has short handbrake travel when it comes in for service, or has a prior history of brake drag, use the Delco/Textar combination set.


Rear brake pad recommendations remain unchanged. All Saab brake pads are asbestos free.

Installation Notes:

1. If there is a brake drag complaint, see S.I. 10/86-895 (S.I. Supplement 6A) before installing brake pads.

2. Refer to S.I. 07/86-863 (Supplement 6A) for complete instructions on installing front brake pads on 900 models 1979-87.

3. Clean and grease the sliding surfaces of the brake housing for the yoke and pads. Use Gleitmo 540 (P/N 30 08 612).


4. Check the hand brake cable clearance at the caliper lever 0.5 +/- 0.1 mm (0.019 +/- 0.003 in.), and adjust if necessary.


5. Turn in the pistons with the aid of the special tool (P/N 89 96 043). Do not turn in the pistons past the point where they are in line with the plane of the hole for the pad retaining pin.
6. The brake pedal must be pumped while the handbrake is set at seven notches before moving the vehicle.


7. When the DM121 four-pad set (P/N 40 04 123) is used on pre-1983 models, the dust boots must be updated to the later material quality and DOT 4 brake fluid only must be used.


Warranty Information:
For owners of 1975-87 900/99's who have Saab brake pads wear out in less than 16,000 miles (where the new car warranty or parts warranty applies), subsequent warranty coverage for wear on the replacement Saab brake pads will only apply if P/N 40 04 123 pad set was installed (parts warranty coverage change effective 6/1/89).
