Camry Wagon L4-2.0L (3S-FE) (1990)
NOTE: Special "bench bleeding" plastic fittings are available which allow for recirculating the brake fluid back into the reservoir.
-
Using a dull object, slowly stroke the master-cylinder piston, air and brake fluid will be expelled from the brake line fittings. Prior to
releasing the piston plug or cap the outlet ports.
-
Repeat this procedure 8-10 times or until no air is emitted from the outlet ports.
-
When finished, cap the outlet ports and install the master-cylinder.
Syringe
-
Fill the syringe (one especially designed for brake bleeding) with clean brake fluid.
-
Insert the end of the syringe into one of the outlet ports on the master-cylinder.
-
Slowly compress the syringe and back flush the brake fluid through the master-cylinder.
-
A combination of air and brake fluid will be emitted from the inlet port in the fluid reservoir.
-
Repeat this procedure until only brake fluid is emitted into the reservoir.
-
Cap the outlet ports and install the master-cylinder.
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.
