Ok got a 82 rx7...... I pressed the brakes and it started to make a loud grining noise. on the left side.. I changed the pads and it stop for like 20 miles now it started it again. it feels like the brakes ao on when on a hill cause it does not roll back. I see some metal dust on the rim. what could this be HELP

 

any one? please need this fixed asap

 

Sounds like you might need to rebuild your calipers. Was there any damage to the boot around the piston?

Is anything physically jammed between the rotor and the pad?

 

Changed my brake pads and mixed up two bolts when i put the right side brake back on, the brakes would drag and randomly lock up on until i switched them back around,they look very similar and it is an easy mistake to make after alot of work, may be something like this

 

nothing was jammed when I took them out, I replaced them and it was fine but after 20 minutes or so it started again. you guys thinkg is the calipers? how much r they?

 

any one else got any info on this?

might as well replace it all while your there, calipers, rotors, pads, and hub bearings.

The Calipers are sticking. Two causes. The slides are binding/stuck or the piston is stuck and holding out. You can grease the sliders and fix it if it is the first one. If the pistons are sticking then you need to do a rebuild. Advance auto has the rebuild kits for appox $9 each. generaly takes a day for them to order them. I have had to rebuild the calipers on 3 cars I have owned and it seams to be a very normal problem. FLush the brake fluid while you are rebuilding them. I can walk you through how to do the rebuild if you need.
