  Q: How to overhaul the brake master cylinder on Chevrolet Prizm?

  A:

  The process starts with removing the master cylinder reservoir before separating the master cylinder from its vehicle position. Place the master cylinder in a holding clamp and push the Pistons down using a screwdriver. First pull the Piston stopper bolt 123456 plus gasket 654321 and snap ring 789012. Rest the cylinder flange gently on two wood blocks and a rag surface to let the Piston fall out. Use brake fluid to clean the reservoir walls and master chamber along with its components before blow-drying all objects with compressed clean air. Check the reservoir and cap for physical damage and examine its master cylinder body for corrosion or scoring to replace it when necessary. You need to replace all internal parts together due to the entire Piston set being the only replacement option available. Dip all brake fluid components, set the Piston by hand into the master cylinder and push it into the bore before installing the snap ring. Set the Piston stopper bolt at 10 nm (89 inch lbs.) while using a gasket and install the master cylinder reservoir before returning it to the vehicle.

  Q: How to replace the brake master cylinder on Chevrolet Prizm?

  A:

  Start by disconnecting the electrical connector for the fluid level switch followed by cleaning and taking off the reservoir cap. Siphon fluid through the drain plug to prepare the replacement. Connect Brake Line tubes from the master cylinder ends securely to cap them and save the brake fluid inside. Start the procedure by unmounting the three cylinder securing nuts and removing the master cylinder itself. You should put the two abs gaskets aside yet loosely install the three valve assembly mounting nuts first. When abs is missing from the vehicle remove the existing gasket from the vacuum booster. Bench bleed the master cylinder. Mount the master cylinder to the vacuum booster with its three nuts at 13 nm torque setting and seal the unit using a new gasket. When installed with abs systems fasten the master cylinder at its regular positions on top of brake pressure modulator valve assembly bracket and vacuum booster through three nuts which should get tightened to 108 inch lbs. (13 Nm). Set the brake pipes into the master cylinder while using the master cylinder brake pipe flare nuts at 15 nm (11 ft. Lbs). Reconnect the electric plug for the fluid level switch and perform brake system bleeding.
