Question about 2002 GMC Yukon XL

1 Answer

Hi, I have a 2002 Yucon Xl and the parking brake pad needs to be replaced. Is the two callaper pins the only thing holding the brake assembly on the disc brake. If so do they come completely out of the pin holes ? Thanks Dave

Yes thats all that holds the caliper on and you can pull them all the way out, but if the bracket that holds the caliper wraps around the front then you will have to remove it also. two bolts.

    You said PARKING BRAKE PAD.... The parking brake shoes are located inside of the rear brake rotors. The rotors have a traditional brake drum machined on the back side and a set of shoes are the parking brake assembly. The Rotor and disc pads that are described above are your normal operating brakes.........

I just had my 2002 Yukon XL rear barkes replaced. New calipers and pads,the parking brake doesn't work. Shouldn't they have found that when they were doing this work?


Of course they should have checked the parking brakes too. On the Yukon XL, the parking brakes are brake shoes that operate inside of a drum that is molded to the interior side of the rear disc brake rotors. I would take it back to the shop and voice my frustration if I were you and tell them that you feel they should do the parking brakes at no charge for your time and aggravation. They were right there to replace them if they re-surfaced your rotors anyway!

How do i replace rear brake pads? And check condition or rotors?


The piston brake pad assembly is usually held in place by two bolts that face the car. Remove these and tap the assembly off .Hang the assembly from a wire.remove the two larger bolts that hold the rest of the assembly in place and remove the rotor.I would simply replace the rotors with after market rather than bother with the old ones.Replace rotor and larger cage.taking carefull note remove the brake pads and compress the brake piston with a C clamp. They should push back with minimal resistance.Check all brake components at this time including the large pins the brake assembly move back and forth on. Install your new pads and replace all the bits.Good luck.P.S. A digital camera might be helpfull if you haven't done this kind of thing before

2003 yucon xl Parkin brake light wont go off when I drive it the warning chimes are on all the time took it to a brake shop siad it was elec problem need to know where the fuse is to turn warning chimes...


Usually it is a switch on the park brake assembly, if you look at the assembly, the switch is either out of adjustment, out of place, disconnected, or has failed.
Should be an easy fix.

Fuse would not just turn off chimes, other items would also be affected.

How to remove rear calipers


  1. Raise and safely support the vehicle.
  2. Matchmark the relationship of the wheel to the axle flange. Remove the wheel and tire assembly.
  3. Reinstall two lug nuts to retain the rotor.
  4. If the caliper is being removed from the vehicle for replacement or overhaul, perform the following:
    • Disconnect the brake hose from the caliper. Plug the opening in the caliper and the brake hose to prevent fluid loss and system contamination.
    • Detach the parking brake cable by lifting up on one end of the cable spring clip to free the end of the cable from the lever.
  5. Remove the bolt and washer attaching the cable support brake to the caliper body assembly.
  6. Remove the sleeve bolt, then remove the caliper body assembly. Pivot the caliper body up to clear the rotor and then slide it inboard off the pin sleeve.
  7. If the caliper is being removed for shoe and lining replacement or to provide access to the support bracket, rotor of wheel brake components, hang the caliper from suspension using a suitable wire hook so as not to stretch or damage the brake hose or brake cable.
  8. Inspect the pin boot, bolt boot and sleeve for cuts, tears or deterioration. If damaged, replace the boots.
To Install:
  1. Install the caliper assembly, as follows:
    • If not replaced, remove the pin boot from the caliper body assembly and install the small end over the pint sleeve (installed on the caliper support) until the boot seats in the pin groove. This is to prevent cutting the pin boot when the sliding body assembly onto the pin sleeve.
    • Hold the caliper body assembly in position it was removed and start over the end of the pin sleeve. As the caliper body assembly approaches the pin boot, work the large end of the pin boot in the caliper body groove. Then push the caliper body fully onto the pin.
    • Pivot the caliper body assembly down, using care not to damage the piston boot on the inboard shoe. Compress the sleeve boot by hand as the caliper body move into position to prevent boot damage.
    • After the caliper body assembly is in position, recheck the installation of the pad clips. If necessary, use a small prytool to re-seat or center the pad clips on the support abutments.
  2. Install the sleeve bolt and tighten to 20 ft. lbs. (27 Nm).
  3. Fasten the cable support bracket (with the cable attached) with the retaining bolts and washer. Tighten to 32 ft. lbs. (43 Nm).
  4. If disconnected, attach the end of the parking brake cable to the parking brake lever by lifting up on the end of the cable spring clip and work the end of the parking brake cable into the notch in the lever.
  5. Unplug and attach the brake hose, if it was disconnected.
  6. Remove the two lug nuts retaining the rotor.
  7. Install the wheel and tire assembly, aligning the marks made during removal.
  8. Carefully lower the vehicle, then bleed the brake system if the brake hose was disconnected.
  9. Firmly depress the brake pedal 3 times to seat the pads against the rotors.
