Power Brake Unit Push Rod
- Install adjusting gauge on master cylinder with master cylinder gasket in place. Lower adjusting gauge pin until pin slightly touches master cylinder piston. See Fig 1 (STEP No. 1). Turn adjusting gauge upside-down and install on power brake unit.
- Measure clearance between power brake unit push rod and adjusting gauge pin head. See Fig 1 (STEP No. 2). Measured clearance should be zero. If clearance is not zero, adjust power brake unit push rod length until push rod lightly touches adjusting gauge pin head.
