This adjustment must be carried out if the brake booster is replaced or after removing the shackle. Before adjusting the length, check the clearance in the push rod and adjust if necessary (see above).
1. Measure the distance between the center of the pivot pin hole in the clevis and the mounting surface of the brake booster housing.
2. If the distance is not correct, loosen the jam nut and make adjustments.
After installing the brake booster, be sure to check the brake pedal height and adjust if necessary (see above).
