When i brake there is a thumping that sounds like it is coming from the back my brake pads have all been replaced and the rotors look ok not sure if the calipers need to be replaced. the thumping is loud and getting worse. also the passenger rear tire wears faster and differently then the other four. could this be a problem with the caliper?
Could be bad calipers too.
No
it indicates that the problem noise is coming from a failing suspension mount and rubber or failing wheel bearings
Take it to an accredited suspension shop that can check/replace the bearings and any failed suspension parts then do the wheel alignment on the rear end first then the front end

Have someone push & release pedal while at wheel with problem. See if it takes a while or slow to release. If yes, have wrench ready on bleeder screw, and try again, if it sticks/holds, crack bleeder screw, if it releases, I'd replace hose.

where do you live meaning if you live on mountain or driving down steep incline every day you will ride brakes every day.that will wear on them a lot.use manual low1 gear coming down mountain.also buy a good brand brakes .i learned a long time ago if you pay more .it will last more.longer.

Testimonial: "thanks for the quick response!!"
I would think it is something going on with the master cylinder or booster. Even the ABS could be affecting it.
