    Driving my 01 today got about 5 miles from my house stopping at a red light, saw/smelled smoke coming from rear pass caliper. Thing is the brake does not drag, car rolls fine, drove home got my inferred thermometer pass rear disc 270 degrees, all other discs 120-125 degrees. Jacked up rear, parking brake off, trans in neutral can spin wheel with no resistance??  So while it was up I removed wheel and caliper, greased the sliders (they were kinda dry) then attempted to compress piston and barely got anything, but the pads are about new so maybe no more to go? I’m thinking may have something to do with the ebrake? But wheel rotates free? Maybe it was just sticky and the grease will fix it?? Will drive tomorrow and see if it worked. Anybody experience anything like this??

    The rear caliper on an NB has a manual adjustment. That is why you’re not able to compress the piston. Located on the back of the caliper, there is a hex nut that covers a recessed Allen head screw that is the manual adjustment.

    Not sure if that will fix your problem, but it’s a start!

    Michael,

    It does sound like a sticky e-brake to me. Easy to check, just have someone set and release it while you keep an eye on the pivot on the caliper. If it is moving freely, you may have fixed the problem by greasing the slider pins. Classic issues after winter storage.

    Good luck, let us know how it turns out.

    Ok so a common issue but I may have messed up with the manual adjustment.. Oh crap had no idea I guess miatas are a little different, have to educate myself  before I treat it like a mustang lol, did not apply too much force on piston. Took it out one time yesterday after greasing sliders and was getting a clicking with rotation of wheel, brakes on or off. I will jump into it again tonight spin wheel and see whats going on..
