2002 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to replace the hydraulic brake booster on 2002 Cadillac DeVille?

  A: Replace the hydraulic Brake Booster by starting with battery negative cable disconnection followed by parking brake activation and blocking both front wheels on a flat surface. The power steering inlet hose and power steering pressure hose and power steering gear to booster hose need separation while removing the master cylinder, wiring harness bracket along with the spacer from the booster assembly. The next step involves taking away the left closeout insulator panel together with the left knee bolster and left knee bolster bracket. Break loose the vacuum Brake Booster retaining clip and foam spacer from the clevis pin at the Brake Pedal before removing the push rod at the clevis pin and extracting the vacuum Brake Booster assembly by unthreading its mounting nuts. You should exchange the vacuum Brake Booster mounting gasket before installing it. Reinstall the vacuum Brake Booster assembly after putting back the vacuum Brake Booster mounting gasket if it needed replacement. Append the booster stud mounting nuts with 36 nm (27 ft. Lbs.) torque while applying gm p/n 12346293 equivalent lubrication to the Brake Pedal clevis pin. After that connect the vacuum Brake Booster pushrod with the Brake Pedal assembly clevis pin in place. Fit the foam spacer combined with the retaining clip to the clevis pin before putting on the left knee bolster bracket and left knee bolster and left closeout insulator panel. The booster spacer together with wiring harness bracket should be reinstalled before attaching the master cylinder onto the booster assembly. The procedure ends with power steering pressure hose installation together with power steering gear to booster hose connection and power steering inlet hose connection. Next comes negative Battery Cable reattachment followed by hydraulic booster system bleeding and front wheel block removal and parking brake disengagement.
