BRAKE SERVICE PROCEDURES FOR 2001 GMC Yukon AUTOMOBILES
Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2001 GMC Yukon cars and light trucks from 1990+.
Disc Brakes -> Delco Dual Piston Sliding Caliper -> Description
Vehicle: 2001 GMC Yukon 4.8 V8 GAS
The caliper mounts in a way that allows the caliper to move laterally inboard as the brake pads wear. The caliper housing is a one piece casting with the inboard side containing the piston bore. The piston seal also acts as a return mechanism for the piston.
Applying the brake pedal causes the hydraulic pressure that moves the caliper piston. The piston then forces the inboard brake pad against the inboard braking surface of the rotor. Increasing the force against...

Power Brake Units -> Delco Brake Booster -> General Service
Vehicle: 2001 GMC Yukon 5.3 V8 GAS
Certain general service procedures apply, regardless of whether the brakes are vacuum or hydraulically assisted. Only top quality, clean brake fluid should be used. 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...

Hydraulic Brake Systems -> Description -> Hydraulic Control Valves -> Master Cylinder
Vehicle: 2001 GMC Yukon Denali 6.0 V8 GAS
Master Cylinder
Some vehicles use a conventional tandem master cylinder with two hydraulic pistons operating in-line. The primary piston controls the front brake system and the secondary piston controls the rear brake system.
Other models use a master cylinder that operates the same as the conventional master cylinder, but also incorporates a quick take-up feature in the rear chamber to reduce excessive pedal travel which may result from increased fluid displacement required to move the low drag caliper piston out against the rotor.
The quick take-up uses a spring-loaded ball check val...
