2001 Buick Regal Brake Master Cylinder Bleeder Tool

When adding fluid to the brake master cylinder reservoir, use only Delco Supreme 11 (GM P/N 12377967) or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container. The use of any type of fluid other than the recommended type of brake fluid may cause contamination which could result in damage to the internal rubber seals and/or rubber linings of hydraulic brake system components.

The procedure is to remove all four tire and wheel assemblies, inspect the brake system for leaks and visual damage, the battery state of charge, install a scan tool, bleed the base brake system, remove the scan tool, install the tire and wheel assemblies, inspect the brake fluid level, and road test the vehicle while inspecting that the pedal remains high and firm.

You can secure the mounting flange of the brake master cylinder in a bench vise so that the rear of the primary piston is accessible, remove the master cylinder reservoir cap and diaphragm, suitable fittings to the master cylinder ports, transparent hoses to the fittings installed to the master cylinder ports, fill the master cylinder reservoir to at least the half-way point, continue to depress and release the primary piston, remove the transparent hoses from the master cylinder reservoir, install the master cylinder reservoir cap and diaphragm, remove the fittings with the transparent hoses from the master cylinder ports, and the master cylinder from the vise.
