Well this weekend I got the job of fixing Chad's rear brakes.  What had happened was his right rear caliper locked up and as a result, turned his rotor red hot.

Looking at the rotor and the caliper, you could tell it got really hot.  The caliper has failed to release the pressure of the pads and just cooked the day light of of them. The following items where replaced:

1. Right Rear Caliper.
2. Rotor.
3. Set of new pads from NAPA.
4. Copper seal/washer for the brake line.
5. All 6 lock washers for the rotor.
6. 3 feet of 1/4 inch vent hose.
7. quart of DOT 5 brake fluid.
 

	This is a shot taken just after I removed the caliper. AS you can see, the pads and rotor are orange from the heat that was generated when the caliper locked up.
	The rotor was all orange, but I the Hummer a few miles to get it to my place to work on it. And it rubbed the rotor a little made it look just a little more like a rotor.  Before it was solid orange like it had been left out to rust for some time.
	While removing the old caliper I noticed that the brake fliud was not looking very nice, in fact as it was filling the glass jar I could see what looked like a mixure of fluids.  Apon a closer look I found multi grades of brake fluid in the system.  In fact I found most of the brake fluid in the system to have been DOT 3 fluid, and just a little DOT 5. As you look into the master Clyinder you can see on top on fluid, and what almost looks like to bottom, is another fluid and some water in it.
	n the photo here, to the left was from the master clyinder, the lower liquid is DOT 5 fluid, the upper lquid is DOT 3 fluid. Th nice purple liquid is fresh DOT 5 brake fluid from NAPA.
	Here is the master cylinder after it was drained out and cleaned up.
