I just bought my 2012 JKU and after a few weeks I started hearing a squeaking noise on the left rear. The old rotor had lining grooves and needed replacing, so for the money the choice of an OEM or these power stops wasn't difficult. some beer and some time to test all 4 brakes, installation went smoothly. I took the Wrangler and did a brake run as suggested, figured I'd wait to check before heading to Silverthorne, Colorado. What could be nicer than a brake test through the mountains! Just got back, brakes/pads worked great! Will definitely buy again if needed! First noticed that the brakes disappear a bit but once the pads and rotors are in place they hold up great! Thanks very much! Update December 2nd: Just wanted to add an update - the brakes and pads are still smooth and stopping my jeep like a champ. No surface rust or any problems! The best brake pack I have ever bought/used!
