Archived Right Rear Brake sticking

[DennyDay]

Had a bad overheat situation on my 2001 and Pulled it apart, alot of crud (winter leftovers) around the rear caliper. Cleaned everything up(both sides, and put on new rotors and pads) and lubed the slide bolts and took it out for a test. It took about 25 miles to get it to heat up, and although it wasn't as hot as it was Friday it did get warm to the touch.



I guess its time for new calipers, I think it is a sticking piston, since only one side is causing a problem. I undertstand this is a problem in this part of the world (Ohio).



Is there anything else I need to look at before I order calipers? They are not real bad $ after market so I will do both sides.



Is there any tricks in bleeding these new brake systems?



Any suggestions would be appreciated.

Bleading is not a problem, the calipers are well designed, just start with bleeding with the point farthest from the master cylinder (right rear, left rear, right front, left front).



You could have a flapper in the brake line. Check the rubber lines, if they have any damage or have any soft spots, that could be the cause of the brakes hanging. A flapper will allow the fluid to go out to the caliper, but when you release the pressure, the soft spot falls in, keeping the fluid pressure on the caliper. Also, excessive rust on the brake hose hanger (where it goes around the hose) can physically squeeze the line shut, causing a flapper.



Finally, how many miles are on that brake fluid? How old is the brake fluid on the truck? If it is over 2yrs old, you should flush and replace it. Having some moisture in the brake system can cause seals to swell and a flapper to occur that way.

Good info

We have 95K on the truck, this winter is the first one in the north lands and it shure has taken a toll.



I've looked at the hoses, and they all looked good w/no soft spots etc.



I'll give the new calipers a try, and decided I might as well do bothe sides and get it over with.



I'll go ahead and flush all the fluid during the caliper change out.



Thanks,

You have most likely checked allready, but just a reminder to make sure the park brake cable moves freely and releases completely, as it can cause the problem.

Good luck, Kuzz
