About two weeks ago I had a caliper hang up on the cherokee, so I stopped at an auto parts store and swapped in a reman one, then just tonight the other caliper stuck and heated up! Are these calipers problematic? Should I get some aftermarket ones?Who makes decent replacement ones?The cherokee is only a beater car and sees mild wheeling duty, just don't want to have problems that could leave me stranded!
