I've searched and I've found it could be anything from a bad top mount to needing a brake rebuild. Anyways, when I have the brakes applied for longer than a couple of seconds, when I release them, it seems like the passenger side rear end pops back up. It feels almost like the spring was compressed a few inches and then let go. Like I said, this only happens when I'm stopped for more than few seconds, not when I first get in the car. Other than this the ride is smooth, so could someone give me some ideas as to what the problem is and what to check? Thanks in advance.
