I have 2006 F350 FX4 with single rear wheels. I had an issue in Fall 2010 where the driver side rear caliper would not release causing the rotor to get very hot..in excess of 500 degrees F as measured with my laser temp probe. As a corrective maintenance, I replaced both driver and passenger rear calipers with Re-man semi-loaded calipers from NAPA.
Move ahead one year:
Starting September 2011, The passenger rear caliper is now intermittently not fully releasing, causing the rotor to get very hot....so hot that it was smoking. Mind you I am not towing anything.
I read that perhaps the brake lines are bad and not releasing pressure. I replaced all of the rear brake lines 3 weeks ago. Still have troubles with passenger rear caliper.
I was told there is a TSB (which I found) that suggests this could be contamination in the power steering fluid. I am going to follow the TSB this weekend and see if it cures the issue. I was also going to clean and replace the caliper hardware...clips, pin bolts, guides, etc.
What else could be the issue?
Please help if you can.
Thanks in advance.
