FRONT DRUM BRAKES
The front drum brakes are self adjusting and very rarely, if ever, require a manual adjustment. For this reason, prior to adjustment, be sure that the self adjusters are working and that the brake linings are not excessively worn.
The front drum brakes on the ff-1 and 1300G are mounted inboard, however, they are adjusted in the same manner as the outboard drums used on the DL sedans and wagons.
If manual adjustment becomes necessary, proceed as follows:
- Block the rear wheels and fully release the parking brake.
- Raise the front of the car and support it with jackstands.
- Remove the rubber inspection plug from the backing plate.
- Adjustment to tighten:
- Insert a brake adjusting spoon into the hole.
- Turn the star-shaped adjusting screw inside the drum with the spoon, until the wheel has a slight drag. Do this to both wheels until there is equal drag on each wheel. DO NOT make the adjustment over-tight!
- Adjustment to loosen and remove the drum:
- Insert a brake adjusting spoon and small prybar to hold the adjusting lever away from the sprocket.
- Back off each adjusting screw until the drum turns freely. If the brake shoes drag with the adjusters backed off all the way, the parking brake cables could be excessively tight.
The front disc brakes require no adjustment, as disc brakes are inherently self-adjusting.
REAR DRUM BRAKES
Perform the rear brake adjustment every 6 months/6000 miles (9600 km) whichever occurs first. Adjust the rear brakes by turning the wedge, which is located on the bottom of the backing plate.
- Chock the front wheels and set the parking brake.
- Raise the rear of the car and support it with jackstands.
- Loosen the locknut on the wedge.
- While rotating the wheel, turn the wedge clockwise until the brakes lock.
- Turn the wedge back 180° ( 1 / 2 turn) from the locked position.
- Tighten the locknut and perform the adjustment on the other rear drum.
