Brake System Bleed
Gravity and vacuum bleeding procedures are not recommended for use with the anti-lock brake system. The manual bleed procedure is the preferred method, although pressure bleeding is also possible. Do not pump the brake pedal during the bleeding process, as fluid aeration may occur.
Manual Bleed
- Raise and support vehicle, then connect a clear plastic tube to brake bleed screw at righthand rear wheel.
- Place free end of tube in a glass jar partially filled with clean brake fluid. Ensure end of tube remains submerged in fluid and master cylinder reservoir is kept full.

Power Brake Units -> Delco Brake Booster -> General Service
Vehicle: 2001 GMC Yukon XL 1500 5.3 V8 GAS

More seals and valves are used with power brake systems than with ordinary brakes, so an inferior brake fluid will do much more damage. For the same reason, ensure all dirt is kept out of the system. Additionally, on models with hydraulic assist brakes, care must be taken not to mix the fluids of the booster hydraulic system and brake hydraulic system as the fluids are not compatible.
If the power unit fails, the brak...
