    Q:
    How to Remove and Install a Brake Master Cylinder and Overhaul It on Buick 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:
    How to overhaul a brake master cylinder on Pontiac Phoenix? Posted by Customer
    A:
    Before dismantling, it is advisable to purchase a Brake Master Cylinder overhaul kit that includes all the necessary replacement parts, particularly the rubber seals, to ensure proper fluid control within the Brake Master Cylinder. During the rebuild procedure, be cautious not to allow grease or mineral-based solvents to contact the rubber parts. To protect painted surfaces from brake fluid spills, cover the front fender and cowling area of the car. Start by disconnecting the electrical lead from the brake failure warning switch and then disconnect the brake line connections, using rags or newspapers to soak up the fluid that will drain out. For manual brake setups, disconnect the Brake Master Cylinder pushrod from the brake pedal inside the car. Remove the two Brake Master Cylinder mounting nuts, take out the Brake Master Cylinder from the car, and drain any remaining fluid. Remove the brake failure warning switch and the two proportioner valves, noting their respective positions as they are different. For further disassembly, it is helpful to place the Brake 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. Next, 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, and clean all parts in denatured alcohol, avoiding gasoline or mineral-based solvents that could damage the rubber seals. Inspect the cylinder bore for any imperfections and use crocus cloth if needed, rinsing the bore with clean brake fluid afterward. Replace the old seals with new ones, lubricate the bore with brake fluid, and reassemble the primary piston assembly. Similarly, disassemble and install new 0-rings and retainers for the switch piston assembly before putting it back into the cylinder. Install new 0-rings on the proportioner valves and the failure warning switch, and insert the quick take-up valve into the cylinder body with its retaining ring. Press new reservoir grommets into the cylinder body, place the reservoir top down on a flat surface, and press the cylinder body onto it with a rocking motion. Install the cylinder on its mounting studs and reconnect the Brake Master Cylinder pushrod (for manual brake setups) and the brake line connections, torquing them to specs. Reconnect the electrical lead to the failure warning switch. Fill the Brake Master Cylinder reservoir with brake fluid and bleed the brake system. Finally, install the reservoir diaphragm and cover, and test drive the car while checking for proper braking performance and leaks.
