Q: How to replace the wheel cylinder on Buick Century?
A: Begin with Wheel Cylinder replacement by raising the vehicle then taking off the tire wheel combination Brake Drum and brake shoes. Clean the Wheel Cylinder area of dirt before removing its bleeder valve but remember to plug exposed brake pipe ends when done. Discard the Wheel Cylinder brake pipe fitting then plug all open brake pipe ends before you take out the Wheel Cylinder mounting bolts and Wheel Cylinder itself. Apply threadlocker product 12345382 or its equivalent on the Wheel Cylinder shoulder where it meets the backing plate and fit the Wheel Cylinder in place. Apply handtools to run the Wheel Cylinder mounting bolts to 12 nm (106 inch lbs.). Join the brake pipe fitting to the Wheel Cylinder and torque it to 15 nm (11 ft. Lbs.) after inserting the pipe ends. Place the bleeder valve and torque it to 7 nm (62 inch lbs.), add brake shoes, set drum brakes, and put back the Brake Drum. Complete the brake system bleeding process before adjusting the parking brake and installing the tire and wheel assembly plus lowering the vehicle.
Q: How to overhaul the wheel cylinder on Buick Regal?
A: Start the Wheel Cylinder service process by taking it off from its current position. Unbolt the Wheel Cylinder then peel back the boots before taking out the pistons seals and spring. Take out the bleeder valve from your system after finishing these steps. Check the cylinder bore interior alongside the Piston parts for damage and irregularities. Wipe corrosion marks with a crocus cloth then get a new Wheel Cylinder when the cylinder bore fails to restore. Put washed parts in denatured alcohol then air dry them using non-lubricated compressed air. Petroleum brake fluid helps these new seals function better. Put the bleeder valve in position then tighten it to 7 nm (62 inch lbs.). Add the spring afterward along with the new seal, pistons, and boots. Finally, install the Wheel Cylinder.
