Master Cylinder: Installation
- To install, reverse removal procedure. Bleed master cylinder bleed screw first, if used, and then bleed remainder of system. See HYDRAULIC BRAKE BLEEDING - EXCEPT POWERMASTER or HYDRAULIC BRAKE BLEEDING - POWERMASTER .
- Check master cylinder compensating ports by pumping brake pedal several times, ending with pedal held down. Remove master cylinder cover and slowly release pedal. Fluid should squirt up in each reservoir from the compensating ports.
- If fluid does not squirt in each reservoir, port is plugged or pushrod is too long. Check for plugged port. If port is not plugged, adjust manual brake pushrod at clevis under dash. On power brakes, see MASTER CYLINDER PUSH ROD
under ADJUSTMENT.CAUTION: DO NOT use wire to check ports. Wire may make a burr on port or damage cup.
- Push rod should have slight amount of play when in relaxed position, so that both master cylinder pistons will return to stops when brakes are off.
