Sounds like it's coming from the rear right, could the break pad be wearing out? Been a short while since I've taken her in for any maintenance work... :sorry
same here.. retorque them REALLY Well.... one of mine fell out. Luckily I was able to get one by the guys at Blow By Racing having some extras laying around... but FORD said in order to get that bolt, I'd have to buy the entire caliper LOL!!!!!!just make sure you tighten and torque those damned caliper bolts down if you take em off... had mine fall out some how? not a happy time!
