My 2010 RG has been having an on again off again front brake problem. The front brakes were hanging up pretty bad but I took the calipers apart, cleaned them real good with ether, cleaned and polished the pucks, put it all back together and it has worked good for a couple of months..... until today..... now it (the front) is hanging up and driving me nuts!!!!! I can hear it, smell it and it drives me nuts!! It has brand new Lyndall Pads in it and I actually have the seals to rebuild the calipers on my shelf in the garage. Is it necessary? Thanks for the help!!!!
