2005 GMC Yukon, rear caliper. Upper bolt just seems to spin, can't find where to hold it with a second wrench. Never tried lower bolt, as I bailed.
How do the caliper bolts come out? It appears that somehow there must be a way to hold the "other" end as you loosen the bolt???2005 GMC Yukon, rear caliper. Upper bolt just seems to spin, can't find where to hold it with a second wrench. Never tried lower bolt, as I bailed.

Pick up a chiltons or hanes rapair manual for your vehicle at your local partys store. most likely, you have to remove one bolt and swivel the caliper assembly upwards.

please explain ,the tightness of the wheel cylinder or thew calipers to the axle ,or the estimated brake resistance reading for a inspection certificate .
remove the front wheel then remove the caliper and brakes then remove the caliper bracket 2 bolts behind fastens to the spindle. The slide the caliper off.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
Front wheel
Clip, 2 caliper pins, the anti-rattle spring then remove the 2 brake pads and the 4 anti-squeal shims
To Install:
CAUTION Only replace brake pads on 1 side of the vehicle at a time. Failure to use this procedure could cause the caliper pistons on the opposite side of the vehicle to pop out requiring the reconditioning or replacement of the brake caliper.
Remove a small amount of brake fluid from the master cylinder.
Install a used brake pad into the caliper and compress the caliper pistons.
Apply disc brake grease to both sides of the inner anti-squeal shims.
Install or connect the following:
Anti-squeal shims to the new brake pads NOTE: When replacing worn pads, the anti-squeal shims must be replaced together with the pads.
2 brake pads
Anti-rattle spring and the 2 caliper pins
Clip
Front wheel
Depress the brake pedal several times to seat the brake pads.
Check the brake fluid level and top off as needed.
Remove the brake master cylinder filler cap and remove fluid until the reservoir is half full.
Raise and safely support the vehicle.
Remove the rear wheel and tire assembly.
CAUTION Never allow the brake caliper to hang from the brake hose.
Remove the two disc brake caliper pin bolts.
Lift the disc brake caliper from the anchor plate and position the caliper out of the way. Do not disconnect the fluid line.
Inspect the disc brake caliper for leaks and replace the caliper if necessary.
Remove the pads and retraction clips.
To Install: CAUTION Do not allow grease, oil, brake fluid or other contaminants to contact the pad lining material.
Install retraction clips.
Install the brake pads.
Slowly compress the caliper pistons with a large C-clamp.
CAUTION Use care not to damage the bleeder screw or front disc brake rotor shield.
Install the disc brake caliper.
Install the disc brake caliper pin bolts. Tighten the pin bolts to 26 ft. lbs. (35 Nm) (F-250, F-350 SRW). Tighten the pin bolts to 56 ft. lbs. (76 Nm) (F-350 DRW). Tighten the pin bolts to 46 ft. lbs. (62 Nm) (F-450 F-550).
Install the wheel and tire assembly.
Lower the vehicle.
Fill the brake master cylinder reservoir with DOT 3 motor vehicle brake fluid.
Remove the wheel , brake caliper / mounting bracket . remove the brake hat there should be an access hole drilled through the hub allowing you to remove the four bolts holding the hub to the spindle . once the bolts have been removed the hub should pull out towards you .. you may need to use a hammer to help get it moving . installation is the reverse of the above
Remove the copper washers and plug the brake hose.
CAUTION: Do not remove the guide pins or guide pin boots unless a problem is suspected. The guide pins are meant to be sealed for life and are not repairable. Use Silicone Brake Caliper Grease and Dielectric Compound D7AZ-19A331-A (Motorcraft WA-10) or an equivalent silicone compound meeting Ford specification ESE-M1C171-A for re-lubing the caliper slide pins. Other greases can swell the guide pin boots, resulting in contamination and accelerated corrosion or wear of the caliper slide pin mechanism. Remove the rear disc brake caliper (2552).
Remove the brake caliper bolts (2W303).
Lift the rear disc brake caliper off the rear disc brake caliper anchor plate (2C220).
Inspect the rear disc brake caliper for leaks.
If leaks are found, disassembly is required. Refer to Caliper in this section.

Removal and Installation
NOTE: When removing the rear brake disc (2C026) in this procedure it is not necessary to disconnect the hydraulic lines. Remove the rear disc brake caliper (2552). For additional information, refer to Caliper in this section.
NOTE: If the rear brake disc binds on the rear parking brake shoe and linings, remove the adjustment hole access plug and retract the parking brake shoe and lining. Remove the rear brake disc.
CAUTION: Use a hub-mount brake lathe if necessary to machine the rear brake disc. For additional information on machining brake discs, refer to Section 206-00 . Measure the rear brake disc, and resurface as necessary. Install a new rear brake disc if beyond specification.
CAUTION: To prevent interference with rear disc brake caliper operation, install only the correct caliper bolt. NOTE: Make sure the stainless steel shoe slippers are correctly positioned. Install new slippers if worn or damaged. NOTE: When installed, the locator notch on the brake pads will be located at the upper end of the rear disc brake caliper. Install the rear disc brake caliper.

I just finished doing the rears on my 2005 T&C. The caliper pins need to be removed with a 7mm allen wrench. I used an allen socket for a 3/8" ratchet, which was much easier than using my wrenches. These pins are threaded and cannot be "tapped" out as said by someone else.
When you replace them, make sure you have some high temp grease to put on them and check the pin rubber boots to make sure that they are not cracked or damaged. Good luck!.
