ok. im tryin to figure out what brakes these are. i really dont think they came off the base model 87 so im guessin the guy before me upgraded them but i wanna know what pads and rotors im going to need to replace them. first clue was the t2 rims and 5 lug then i took off the tires and found the....4 piston or 2 piston calipers....please excuse me...i dont know but i know its not the stock ones....maybe from a t2....whatever those are. so maybe someone can conferm with me....could they be t2 brakes and rotors?

Stock would be a single piston caliper with two bleeder screws on the rear, and only one bleeder screw up front.

yea....i know. but what do these come from? ill take a picture later today if it will help. i would think there are only 2 types of brake calipers but maybe there are more. all i do know is that they are not what should be there. but they sure look nice....just too bad the rotors are rust *****.

BIG 5 lug 4 piston/vented rear brakes came on 86-87 sport (unmarked model,
btw), 88 GTU, 89-90 GTU-s, all 87-91 turbo 2, all 88-91 convertible, and all
86-90 GXL. The 91 NA/coupe (there were no trim levels other than NA or
turbo) is sort of an oddball and could potentially have these, but generally
they have the small version. There is no difference between
year/series/model, all the big brake setups are the same. The only
difference would be that a few of them had abs and most didn't. The abs
sensor is mounted on the spindle/housing, while the rotor is mounted on the
front wheel hub or the rear axle.

SMALL 5 lug single piston/nonvented rear brakes came on 89-90 GTU (base) and
most 91 coupe cars.

SMALL 4 lug single piston/nonvented rear brakes came on all 86-87 base
(unmarked model) and 88 SE.

maybe this will help. the rear brakes are just the normal single piston brakes that i always saw. but are these calipers in the picture the ones that were on the car? i have a 87, non power windows, power steering, cruse control, storage buckets, non turbo, umm....i dont know what else would make a differance in the model but carfax calls it a turbo 2. but mazda said it was some can model. so im kinda lost on what it should have and what to ask for when i go for parts.
