Can adjusting the handbrake cause the rear calipers to seize? The reason i'm asking is that I had the handbrake adjusted on my MR2 and I was told the brakes were okay, then a week later after not driving it I noticed a lot of heat coming from the rear passenger side caliper. I took it back and they told me the caliper had seized and I would have to pay to have it replaced. I purchased the car from with a three month warranty, now expired. I have now purchased a warranty from warranty direct, after this happened, so not covered. I am in process of having my fiance company who financed the car for me. Are the garage at fault? I had no caliper problems before they adjusted the handbrake
