now, i have a previos post about my power brake that might be related, so i thout it was worth mentionig.however i personaly doubt it.

ihave a rattel in the rear end when i hit farly big bumps. now i know that the exhaust is solid. maby shocks but not shure because all this started after a recent brake job" fronts and backs with roters". the rear calipers have the pins bolted to the calaper insted of bolted to the caliper bracket like im used to seeing. so maby i did someting wrong

also thare is a squealing when i hit the brakes and come to a stop but i think that has to do with the brake in prosses or thay might be slietly glazed

 

yea I would say the squeal would be from the new parts. As far as the rattle, take the tire off and shake the caliper, if it's loose then tighten.
The rattling could also be shock/strut bottoming out. Other than that, just get under there and look carefully.
