    Q:
    How to Remove and Install a Master Cylinder and Overhaul It for Buick Century and Regal? Posted by Customer
    A:
    The removal and installation process for brake master cylinders is detailed as follows: Tag and disconnect hydraulic lines, cap lines to prevent leakage, and remove the brake master cylinder attaching nuts, then remove the brake master cylinder. For non-power brakes, disconnect the push rod from the brake pedal. To reinstall a non-power brake master cylinder, position it against the firewall with the push rod inserted, tighten attaching nuts, and attach the push rod to the brake pedal. For power brake systems, position the brake master cylinder over the push rod and tighten nuts. Install hydraulic lines and bleed the brake system. During overhaul, remove the brake master cylinder from the car, eliminate mounting gasket, boot, and main cover, drain the fluid, secure the cylinder and remove push rod retainer and secondary piston stop bolt. Compress the retaining ring, extract it with the primary piston assembly, use compressed air to force out the secondary piston, spring, and retainer. Check brass tube fitting inserts, replace if needed. Clean parts with denatured alcohol and compressed air. Replace brass tube inserts by threading brake line tube nut, then position and identify piston assemblies, place secondary seals in grooves, assemble primary and secondary seals and protector, insert assembly into cylinder, seat spring against bore, push in primary piston, snap retaining ring, replace reservoir diaphragm and cover. Overhaul of power brake master cylinders' main cylinder portion follows the same steps as for manual cylinders.

    Q:
    What are the steps involved in the disassembly of the master cylinder for the 1985 Buick Skylark? Posted by Customer
    A:
    Remove the brake failure warning switch and the two proportioner valves, noting their respective positions as they are different. Place the master cylinder in a vice with blocks of wood on either side to avoid overstressing the aluminum body. Use an Allen wrench to remove the switch piston plug and extract the switch piston assembly from the bore. Remove the primary piston retaining ring and then the primary and secondary piston assemblies. Also, remove the plastic reservoir and the quick take-up valve retaining ring.
