2003 GMC Savana 3500 Brake Booster Parts Questions & Experts Answers

• Q: How to replace the hydraulic brake booster on 2003 GMC Savana 3500?

  A: The replacement process of hydraulic Brake Booster starts by using the park brake along with wheel blocking. Keep the master cylinder connected to its pipes but remove it from the booster before disinapping the inlet hose and steering gear along with the return hoses from the booster assembly. The engine compartment receives the master cylinder before workers remove the stop lamp switch which leads to removing the 4 booster to bulkhead nuts. Separate the booster assembly and you will find the gasket. You should place the new gasket first before installing the booster assembly. Install the 4 booster to bulkhead nuts while torquing them to a specified 36 nm (26 ft. Lbs.). First reinstall the stop lamp switch and master cylinder before connecting the return hose with the steering gear assembly followed by the inlet hoses. Following hydraulic system bleeding users must perform brake release before unblocking the wheels. Exercise extreme caution when working with brake fluid because it can both harm electrical parts and human skin tissue alike as well as damage components; utilize the right fluids as hydraulically operated brake systems use power steering fluid in the booster and brake fluid in the master cylinder and brake pipes.
