Push Rod Adjustment Notes

PURPOSE
The push rod is a straight linkage which transfers the force developed by brake booster to the master-cylinder. The length of the push rod determines the maximum amount of travel of the master-cylinder piston.

ADJUSTMENT
Push rod length can be adjusted by unlocking and rotating the adjustment nuts. Correct adjustment is very important for proper braking.

Too Long - A push rod which is too long may cause the master-cylinder piston to over-travel. This may damage the pistons seals and lead to a master-cylinder failure.

A push rod which is too long may also cause the piston seals to block off the compensating port, which may cause brake drag or lockup.

WARNING: If vehicle has had repeated master-cylinder failures, verify the pushrod is not over-extended.

Too Short - A push rod which is too short may limit the amount of brake pressure developed and reduce the overall braking ability of the vehicle.
