1996 Oldsmobile Eighty-Eight LSS FWD V6-3.8L VIN KSECTION Adjustments
The switch assembly and valve assembly cannot be adjusted until brake booster pushrod is assembled to brake pedal assembly. Adjustment is as follows:
1. Depress brake pedal and install switch assembly and valve assembly into their proper retaining clips until fully seated.
2. On vehicles equipped with ABS, release brake pedal and allow to come to rest.
3. On vehicles less ABS, slowly pull pedal back to its fully retracted position. The switch assembly and valve assembly will move within their retainers to their adjusted position.
4. The following brake pedal travel distances may be used to check for a properly adjusted cruise control and stop lamp switch assembly and vacuum release valve assembly.
a. Cruise control switch contacts must open at 0.88-1.2 inch pedal travel, measured at centerline of brake pedal pad. Nominal actuation of stop lamp contacts is 0.4 inch after cruise control contacts open.
b. Vacuum release valve assembly must open at 11/16- 1 5/16 inches pedal travel, measured at centerline of brake pedal pad.
