The front and rear disc brakes require no adjustments. Hydraulic pressure maintains the proper pad to disc contact at all times. However, the parking brake shoe on the rear disc brake systems must be adjusted manually.
The rear drum brakes, on your car, are self adjusting. The only adjustment necessary should be the initial one after new brake shoes have been installed or some type of service work has been done on the rear brake system.
After any brake service, obtain a firm brake pedal before moving the car. Adjusted brakes should not drag. The wheel must turn freely. Be sure the parking brake cables are not to tightly adjusted.
Since no adjustment is necessary, except when service work is done on the rear brakes, we will assume that the car is jacked up and properly supported. If not, then refer to the appropriate sections of this section for the procedures necessary. Adjust the rear brakes as follows:
- With the vehicle raised and properly supported, remove the inspection plug from the top rear of the brake backing plate.
- Insert a suitable brake adjusting tool into the inspection hole and turn the star adjuster until the wheel cannot be turn any more.
- Insert a long narrow rod through the inspection hole and hold the automatic adjusting lever away from the adjusting bolt.
- Using a suitable brake adjusting tool, insert the tool through the inspection hole and reduce the brake shoe adjustment by turning the star adjuster counterclockwise.
- Reduce the brake shoe adjustment enough to allow the wheel to spin freely at least one full revolution.
- Do the same to the other wheel and then lower the vehicle.
PEDAL HEIGHT AND FREE-PLAY
The correct pedal height from the floor boards to the brake pedal should be 166-176mm (6.54-6.93 in.) for 1983-88 or 157-167mm (6.18-6.57 in.) for 1989-90 on the Cressida, and 148-158mm (5.83-6.22 in.) on the Van models.
- On the Cressida models, remove the instrument lower finish panel and air duct.
- Loosen the locknut and turn the stop light switch and the brake cancel switch for the cruise control (if so equipped).
- Adjust the pedal height by turning the pedal pushrod until the correct brake pedal height is obtained.
- Return the stop light switch and brake cancel switch until it they lightly contact the pedal stopper.
- After adjusting the brake pedal height, check the brake pedal free-play.
- With the engine OFF, push in the brake pedal several times until there is no more vacuum left in the brake booster. Push the pedal in until the beginning of resistance is felt. Measure the distance from the stand still point till the free-play point. The brake pedal free-play should be as follows:
- The brake pedal free-play should be 3-6mm (0.12-0.24 in.) on the Cressida models.
- The brake pedal free-play should be 1-4mm (0.04-0.138 in.) on the Van models.
- If it is necessary to adjust the brake pedal free-play, use the following procedure:
- Adjust the brake pedal free-play by turning the pedal pushrod.
- Start the engine and confirm that the pedal free-play exist.
- After adjusting the brake pedal free-play, recheck the brake pedal height.
- Reinstall the air duct and lower instrument finish panel one the Cressida models.
