• Q: How to replace the brake master cylinder on 2004 Chevrolet Malibu?

  A: You must first remove the vacuum check valve from the vacuum Brake Booster grommet to remove its vacuum content during Brake Master Cylinder replacement. Unplug the electrical sensor and take away all brake pipes from the master cylinder. Seal exposed pipe ends with rubber plugs to retain brake fluid. Check for damage on the master cylinder seal against the vacuum Brake Booster and get a new seal when needed before removing master cylinder nuts and pulling out the device. When the reservoir will be used again take it out of the master cylinder. After assembling the reservoir with the master cylinder if necessary you should bench bleed the system and verify that the seal rests flat on the master cylinder bore before reinstallation. Install and tighten the Brake Master Cylinder nuts to 25 nm torque. Then install the brake pipes to the master cylinder slots and secure them to 20 nm torque. First connect the electrical parts to the Brake Fluid Level Sensor while reinstalling the vacuum Brake Booster check valve into the grommet space. Then complete the brake system by draining all air from the system.
