Right rear caliper. This past weekend i found the pads had worn to the rivets and a huge groove in the rotor. (I guess headers and flowmasters can mask a lot of noises!). I put a brand new rotor on and some all but brand new pads. This is from no more than 15 miles of driving, probably more like 10. Oh, also, the left rear pads and rotor had plenty of life left. My buddy says my RR caliper is seizing up. What do ya'll think? Could these darker spots just be the pads and rotor breaking in? Fwiw, i found this because i took the wheel off to put brand new pads on both rear wheels. All but brand new pads. The one with the discolored arc is the outside pad. Brand new rotor, less than 15 miles of driving
After driving was wheel / rotor HOT , if so something is hanging up . Could be caliper but also it could be a collapsed internally rubber brake hose . The hose could be allowing brake fluid to the caliper , due to system pressure but not allowing fluid back through the hose when off the brakes . How old are the hoses ?
Hose is at least 17 years old because ive never replaced them since ive had the car. I do have a laser thermometer, so i can compare one side to the other after driving.
Remove right rear tire. Have a wrench ready that fits the bleeder screw. Push hard on the brake pedal then quickly open either bleeder.
If fluid squirts out instead of a dibble, its likely the hose has turned into a one-way check valve.

I ahould have clarified, the front hoses and pads have been done along with replacing one leaky front caliper. Back brakes have not been touched in the 17 years ive had the car, about 35000 miles of driving. Im going to do new back hoses, a new RR caliper and new pads on the back. While im there i think i'll take a stab at the RR parking brake (seperate issue, that led to me discovering the problems with the old RR rotor and pads). Theres no parking brake parts at all beyond the cable on the RR wheel. Would love to go back in time and find out why someone would do some jack leg work like that!

don't buy hose at local napa or chain.. they are chinesium if it matters to you..and one i got was DOT already 9 years old.
on e brake etc.. here is my thread that i got a lot of help on and advice.. my guess is it's easier to just let the parts fall out than fix and not drive.. i would check run out on the rotor as well. consider keeping caliper if not leaking and working.. new ones crap shoot..especially if you like the delco original ones. consider rebuilding if SS lined with o rings, otherwise if they do not leak and are functional.. i would not mess with.
Consider stainless steel braided brake lines, if possible
Bleed the brakes. I don’t think Corvette owners bleed brakes too often. This becomes important if the car sits all winter. Brake fluid absorbs moisture. Moisture makes the inside of your calipers rust. Then they leak and could bind. If you replace you calipers, consider ones with stainless steel inserts.
RR axle will wind up with all new components from the rubber brake lines back, to include new rubber usa made brake hoses, stainless steel from there to a new caliper, new rotor and new pads. Also putting in all new parking brake axle parts (from the cable back) because some bubba in the past removed everything beyond the cable. Drivers side is getting new pads, new rubber hose and new SS caliper hard line to replace where someone rounded off the fitting to the hose. Caliper, rotor, and parking brake components good to go on the drivers side. In fact, the drivers side parking brake even held the car if there was only a slight incline.
