Disc Brakes -> Delco Dual Piston Sliding Caliper -> Description
Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 FLEX

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...

BRAKE SERVICE PROCEDURES FOR 2003 GMC Yukon XL 1500 AUTOMOBILES

Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2003 GMC Yukon XL 1500 cars and light trucks from 1990+.

Anti-Lock Brakes -> Kelsey-Hayes -> Description
Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 FLEX

When wheel slip is detected during a brake application, the ABS enters anti-lock mode. During anti-lock braking, hydraulic pressure in the individual wheel circuits is controlled to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold, or increase hydraulic pressure to each wheel brake. The ABS cannot, however, increase hydraulic pressure above the amount which is transmitted by the master cylinder during braking.

During anti-lock braking, a series of rapid pulsations is felt in the brake pedal...

Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported 2003 GMC Yukon XL 1500 cars and light trucks from 1990+.

Power Brake Units -> Delco Brake Booster -> General Service
Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 FLEX

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...

Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 FLEX

Height Sensing Proportioning Valve

The height sensing proportioning valve must be adjusted whenever the valve and/or linkage is disassembled or removed for service. In addition, adjustment should be inspected if excessive front wheel lock-up is experienced with a lower than desired brake application rate when vehicle is at or near maximum GVWR.

  • Raise and support vehicle, leave wheels on and allow axle to hang freely.
  • Remove lever retaining nut and disconnect lever from valve shaft,. Fig. .
  • Rotate valve shaft to permit installation of correct adjustment gauge,. Fig. , ensure D shaped hol...

Vehicle: 2003 GMC Yukon XL 1500 5.3 V8 FLEX

Brake Lines & Linings

Remove one of the front wheels and inspect the brake disc, caliper and linings.

Do not allow any oil or grease on the linings. It is recommended that linings be replaced in sets when worn or damaged.

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.

Brake Roughness

The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickness v...
