I have a Born Free 2004 RV that is having brake problems.?

I have a Born Free 2004 RV that is having brake problems. Pulled into our house and parked it months ago then took it out to drive to fill up tank and the right back and right front wheel started smoking with a burnt smell. Brake pads are good, rotaries are good, no ABS light or Brake light on the console. Parked it, then drove again a few days later, no smoking, everything fine. Parked, then drove, and smoked again. Help!

Brake trouble light not on, no brake fluid leaks. If master cylinder wouldn't all brakes be affected? I pulled the right front wheel & put pressure on brake & it brakes & releases just fine. I can't believe all calipers are bad at the same time. Would the flex hose be collapsing when it gets hot? Can't tell that and they look & feel fine & no signs of leaks. Put new caliper on left rear & it is working. Also put new flex hose on. New pads. Could it be an electrical issue?

Sounds like you have a brake caliper locking up intermittenly. The moving parts of your caliper may need lubed or you may need a new caliper all together.
