One more thing Hopes, pull the rear wheels off and see how clean the seal area is on the backing plates , if it just has 6 grand on them it all will look like new.. jmo
Planed on doing that and change the fluid. I have to get the undercoat off the bottom actually flaking off and clean meatal under it so far and no "dirt" buildup on it either. The cover also has a blue paint mark on it.
If the rear brakes have never been off, there should be that flat washer (pal nut I think they are called) that holds the rear drums on the axles... The factory used them to hold the rear drums on, when you remove the drums on a virgin car, you have to break off those pal nuts with a side cutter....
If it is truely a 6 k mile car, they shouldn't have done any rear brakes yet....
