I thinl that I have a slightly dragging rear brake caliper.

After driving 12 highway miles to work with using brakes minimally, the right rear rotor is warm to the touch when the other three are cooler. Is a slight brake drag normal?

But I do wonder...if the rear rotor retracts only by turning it clockwise, how is it that it relieves the pressure from the piston?

Thanks.

 

Yes, i had to replace one of my rears

 

If you can touch it after 12 miles, it's definately not dragging at all.

 

Thanks for your reply.

I had recently noticed that the left side rear pads were dragging and wore the pads down to the metal plates. Upon disassembly, I noticed that the brake pad was not properly aligned in the piston groove and that there was a slight residue on the piston that may have also hindered its retraction into the caliper. I used a little liquid penetrant and flushed it out with clean brake fluid.

Its seems to have subsided for now, except that the right rear was the only one warm to the touch. Thats why I was concerned and hope that the pads does not wear down again prematurely.

I put the old pads (half worn) back in to make sure it won't be a problem before I install new pads...again. I was hoping that I didn't have to replace the caliper.

Thanks guys.

 

Replace those rear calipers they do seize and create a headache for you when it comes time to change the rear pads and you cant seem to turn the piston back in.
