I have a 87 420 SEL with 150k on it. Lately I have begun to hear a muffled popping sound coming from the RR after I have braked at a stop sign. I also hear it after I have pulled the car into the garage, turned the key off and am walking out the garage door.
I haven’t looked under the car yet, but my suspicions are its brake related. Anyone else have any ideas where to focus on or had this problem before? Thanks
