Power Brake Unit: Installation

Check booster-to-master cylinder push rod length at measurement "L". See Fig 1 . Length should be .394" (10.00 mm). Use care when handling booster assembly. Excessive lateral force to operating rod will damage power piston cylinder.
Ensure booster resin material around brake pedal rod is not damaged. Replace power booster assembly if it is dropped. To install, reverse removal procedure. Bleed hydraulic system. See BLEEDING BRAKE SYSTEM .
