How to replace the brake master cylinder on Buick Century?

First step to replace the Brake Master Cylinder is disconnecting the Brake Fluid Level Sensor and the brake pipes from the master cylinder while installing rubber caps or plugs to seal the open brake pipe fittings to prevent brake fluid loss and contamination. Install brake pipe caps then loosten the master cylinder unit bolts to extract the master cylinder with complete drain of brake fluid. Before installation into the vacuum Brake Booster you should bench bleed the master cylinder then install and secure its mounting nuts to 25 nm (18 ft. Lbs.). Join the brake pipes to the master cylinder and fix the pipe connections at the master cylinder with 15 nm (11 ft. Lb) torque settings. Attach the electrical connection to the brake fluid sensor then perform brake system bleeding.

How to overhaul the brake master cylinder on Buick Century?

After detaching the master cylinder you need to place its mounting flange in a bench vise and make sure you can reach the back of the primary Piston. Check the reservoir area outside the cap for damage before taking off the cap and checking both components for harm to replace them when needed. After separating the cylinder reservoir attach a round tool to press the main Piston down and take off its retention ring and single Piston unit. Insert plugs into the cylinder ports while running filtered non-lubricated low-pressure air into the outlet port to push out the secondary Piston assembly combined with the primary and secondary seals and return spring. Throw away both the primary Piston parts plus the Piston retainer and seals from the secondary Piston. Thoroughly clean the inside and outside areas of the master cylinder, secondary Piston, and return spring using denatured alcohol or an equivalent solution and inspect them for damages such as cracks, scoring, pitting, and corrosion before replacing the entire master cylinder if any findings are detected. Blast all parts with air filtering that excludes oil and apply delco supreme ii brake fluid gm p/n 12377967 (Canadian P/N 992667) or dot-3 equivalent to the cylinder bore, secondary Piston, return spring, and all service components. Add the lubricated new primary seal and retainer plus secondary seal to the secondary Piston and put in the lubricated return spring along with the secondary Piston assembly into the cylinder block. Install the lubricated primary Piston assembly last. Push the primary Piston with a smooth tool then put on the new Piston retainer and reinstall the master cylinder parts.

Brake Master Cylinder is useful part of the cars and especially Buick Century automobiles because it translates the pressure of the foot of the driver into hydraulic pressure in order to manage the brakes of the car. Its action is achieved by pumping hydraulic fluid through the system to make use of calipers or drum to provide the amount of friction essential to halt the automobile. Normally, the Buick Century comes with a dual circuit master cylinder to make certain that if a certain circuit is incompetent, the other can still deliver energy to the braking system. Depending on the model of Buick Century, the Brake Master Cylinder might employ cast iron or aluminum housing for the cylinder, and may feature integrally or extraneously mounted fluid reservoirs. The integral reservoirs have only one cap while the external reservoirs have one or two threaded cap types. There are often such problems as leakages or internal malfunction which may necessitate closer examination to provide maximum stopping power.
