I have a question regarding the rear brakes on my 2007 wrangler JK (50000 miles). A friend of mine replaced my rear pads today as I watched (learning) and we did not install the 8 metal clips that came with the pads. Can anyone tell me anything about this please? I also noticed a shake after driving for 20 miles going around a corner and my ABS light flashed. Related? We also didnt replace the rotors as they were on too tight and actually looked fine and smooth. Thanks for any help....not a mechanic as you can see.
