Front right brakes locks. Changed the brake lines as well as the master cylinder,and the calipers.,bled the lines. car drove great fro 15 miles and then the right brake froze up again. was told by Jeep Dealer that it was the hydraulic repositioning valve.. does that soung right?
It also sounds like a more likely problem is a seized caliper on the left side. If a caliper seizes, the braking system transfers the pedal pressure to the other caliper thus, the working caliper locks up. Pull both front wheels and look carefully at the wear on the pads. Both wheels should have the same amount of wear. If one side is worn more than the other, the side with the least wear is seized and needs to be changed.
Never heard of a hydraulic repostioning valve, but maybe with ABS there is one. I do know of a proportioning valve which apportions brake pressure front to back and also blocks braking to front or back in the event of brake line failure. Maybe see which he is talking about, should be able to explain the difference. Hope this helps.

Hope this helps to solve it; remember to rate this answer.

thanks . it is the proportioning valve. would this make a difference? Dealer wanted to charge $600.00.got one from auto salvage for $20.00 put in on late last night but have not driven yet.
the passenger side smoked like crazy and the caliper locked.
seems like the caliper is closing but not opening up. we did put a new one on the passenger side.
should we change the caliper on the drivers side.?
thanks so much,
