I have a 2006 Grand Cherokee and since I bought the car used the rear right brake has squealed despite having the breaks replaced and serviced twice. I have had the car for less than a year. Recently I have noticed a bit of a shake/thud while I’m driving at speeds lower than 45mph. It almost feels like I have a flat tire, despite all of my tires being properly inflated. I do not have to be pressing the brake to feel the shake, however I do feel the vibrations in the brake pedal. Any idea what could be the problem and could it be dangerous? ---

Sounds like you have a binding rear brake caliper…I AM taking a leap of faith here and totally assuming that you DO have a rear caliper…and not rear drums. But methinks the Grand Cherokee did have 4 wheel disc brakes… If so, its that right rear caliper… DO THIS…go for a longish drive…get the noise to occur and that feeling in the brake pedal… Then stop get out and FEEL your rims/wheels…is the right rear Hot? Or is it at least higher in temp than your left rear? If so this is further proof of a binding caliper Blackbird ---

Thanks, you are correct the Grd Cherokee does have 4 wheel disk brakes. I will try your suggestion this afternoon. Supposing I do find that you are correct and I have a binding caliper, is that something I need to get fixed right away? Thanks again and don’t forget don’t drive like my brother! ---

If it binds, get that fixed as soon as possible. It is like someone steps on the brake, but only for that one wheel. That’s not a good condition to have. He’ll likely replace the caliper, maybe turn the rotor but possibly replace it and do a brake job on both rear wheels, if that is the case. It could be wheel related as well, though. I’ve had a bad tire that had a manufacture defect do that to me. Could also be that one or more rotor is warped.
