2006 Buick Lucerne Parts Questions & Experts Answers

• Q: How to replace the brake master cylinder on 2006 Buick Lucerne?

  A: Start by disconnecting both the Brake Fluid Level Sensor and brake pipes from their connection to the master cylinder as well as the electrical connector. Seal brake pipe ends with rubber caps to keep brake fluid inside and protect it from damaging foreign particles. Take out the Brake Master Cylinder by removing its two bolts from the mounting points. Keep the reservoir when planning to reuse the setup. Detach it from the master cylinder for this purpose. After unit removal place back the Brake Master Cylinder reservoir onto the master cylinder and complete a master cylinder bench bleed process. Fit the master cylinder to the vacuum Brake Booster using its two mounting nuts at 18 foot-pounds torque. Use a socket wrench to join brake pipes and master cylinder with 33 nm torque. After reconnecting the electrical connector to the Brake Fluid Level Sensor perform hydraulic brake system bleeding.
