car.. 2006 base 350z non brembo
car has 30 k miles... no rust / leaking or damage on the brakes.

problem.. right rear break dragging lightly.. causing heat..


ok so the car needed new rear brake pads.. and when almost worn.. the right rear started screeching and started rubbing really hard and when brake was applyed bounced like abs...

brought it home.. installed new pads... i needed a c clamp with allot of force to push the piston back in and the other side went in like butter..

reservoir cap removed..

now new pads installed.. the right rear that the piston wont move easy keeps rubbing..

am i needing to replace the piston seal?

i dont know if it has to do with anything .. but if i drive and lightly pull the ebrake it make a huge clunk in the rear....
i am wondering if the ebrake might be draging as well . it only makes the clunk the first time pulled.. after that no clunk..

thanks for any help...

 

Rebuild or replace the caliper.

 

I replaced a caliper on my G35 at about 60,000 miles because I was having the same problems.
