    Well, the RR caliper is drying in the oven but I did take photos of some of the front brake parts.

    The OE calipers were Australian, from a company called PBR Brakes USA. The new replacement Calipers and Rotors are Akebono. The new OE hoses are Flexitech.

    The front and rear pistons are the same. Checking with Rene to see if the seals and gaskets are as well. When the RR caliper comes out of the oven I'll look for makers marks.

    No complaints, they lasted 150K miles and stopped 13K pounds like it was nothing.

    Still sitting in the driveway on stands waiting for a part. Should arrive today and then I'll rebuild the last rear caliper and put everything back together over the weekend and get the brakes bled, hopefully they work!

    GM does not list any parts to rebuild the rear aluminum calipers. But the parts to rebuild the fronts are exactly the same. So I have rebuilt one and waiting on a new bleeder screw (fine thread) to rebuild the other and get this thing back on the road.

    Quite busy with home, kids, other car repairs and work so my time spent on here will be limited for a while. Haven't forgotten about you Okeechobee boys, I'll ring you all up soon when my truck has its wheels on again!

    Tell me about it Tony! Saturday wiped me out and the girls did most of the work! They changed the oil in the other two cars, a hub in the Montana and helped me finish up the truck's brakes.

    Finished burnishing the brakes just after midnight last night. Took the family to dinner tonight and all seems well with the brakes. During the draining out of the old fluid and refilling with new, the ABS and manual bleed processes, we went through 5 quarts of brake fluid! Truck stops as before, pedal feels the same, pressure is still in the mid 800s but only takes in the 60s to slow the truck.

    I'll come back in a few days or weeks with part numbers and torque specs like was done for the fronts for those who come along after us. Wife is now chomping at the bit for a Yukon Denali! One daughter should have enough money saved to buy a 6.2 NHT Sierra by December or January. These are hard to come by, especially in SLE trim, so it may take a few months to fine the right one. It's gotta have the trailer brake controller too! Same with the Denali!

    Oh, that's the current supplier for GM OE rotors. Don't recall maker's marks on the ones from last year but will check again before using them as weights.

    For anyone coming along later on and needs some part numbers:

    Brake Caliper, Rear, Left = 84191288
    Brake Caliper, Rear, Right = 84191287

    I did not buy these new calipers but am providing the numbers for reference.

    The pistons come 1 to a box, the seal and boot kit will service two pistons. The bleeders for the rear aluminum calipers use a fine thread whose part number is provided below.

    Brake Caliper, Piston = 15125962
    Brake Caliper, Seal and Boot Kit = 23276875 or 179-2262
    Brake Caliper, Rear, Bleeder Screw = 88967108

    These are GM Original Equipment numbers. Many thanks to Rene for confirming these numbers and providing the GM pricing for comparison. @915_Tahoe

    The brake caliper bolts are 13mm and the slide pins take a 20mm wrench. The brake caliper bracket bolts have 18mm heads. The caliper bracket is supposed to have some loc-tite on it and torqued to 122 FT LBS, while the caliper bolts get torqued to 28 FT LBS. When torquing these down, you have to hold the slide pin with the 20mm wrench, but DO NOT let the wrench touch the caliper while tightening or torquing as vibration may ensue while breaking. I do not understand why, that's just what the manual says. The Brake Hose to Caliper Bolts get torqued to 30 FT LBS and has an 11mm head.
