Burnt Brakes

[NCHornet]

Your caliper is hanging up!!!! Heat = expansion, Cold = contraction, remove the caliper, pull both slide pins and inspect them and the boots, clean or replace, then clean the bores out with brake cleaner. Use dielectric grease ( caliper grease) to relube the slide pins and reinstall. I would also replace the pads on both sides. Hawks LTS or Friction Performance from AZ are good pads, you need to change both sides!!! There is no way you rear rotor should be that hot, the only thing that builds that kind of heat is friction!!! Your fronts do 90% of the braking and even they don't get "spit sizzl'in" hot under normal use. This should fix your problem. I would also have both rotors turned while they are out. You can't eye ball warpage.

Right out of the box i thought it was the slide pins.However,the slide pins moved freely and had adequate lube.Could the caliper pistons be sticking?

[NCHornet]

Yes the caliper pistons themselves can stick. I think I paid $50 for rebuilt loaded calipers from Napa, this will come with new pins, boots and the caliper itself. I would change it and you know this should take care of it.

Did you get the hot brake on the right rear fixed? i have the same problem on the left rear.

You say the caliper seems fine. I'm not sure of the dually brake system, but on the SRW, there is a parking brake drum setup BEHIND the rotor. If it is the same, check to see that it isn't hanging up, or a parking brake cable is siezed up.

First time i hear about dielectric grease for them pins, i use antiseeze on mine but i got to do them about every 4-6 months. Does dielectric grease last longer ? what else do you guys use to lube the pins ?

[ns954]

I replaced the right rear caliper and the pads on both sides.I lubed the rear caliper slide pins with the dielectric grease that ford sells.I did not turn the rotors,as there appeared to be no warpage.I have put 15,000 miles on the truck since this incident with no problems.Knock on wood.Hope this helps.

Glad to hear it. Anti seze IS NOT the proper lube for the slide pins. Ford sells a special caliper grease, I think it is called F8 or G8 something like that, but all it is , is dielectric grease. Same as caliper grease that you find at any auto store.

my truck did the same thing
replaced the caliper and have not had a problem since
just be carefully bc after my back right went, next was the front right, then the front left
so keep an eye on them
