Power Brake Booster: Installation
- Prior to installing power brake unit ensure that booster rubber reaction disc is properly installed. See Fig 1 . If the master cylinder push rod is removed or accidentally pulled out, a dislodged disc may cause excessive pedal travel.
- The reaction disc is Black, compared to the Silver valve plunger that will be exposed if push rod and seat are removed. To install power brake unit, reverse removal procedure. Start engine and check for proper brake operation.
NOTE:
Booster must be replaced if reaction disc cannot be properly installed and aligned, or if it cannot be located within the unit itself.
