I pulled the ebrake and now it wont disengage!  I didn't reef on it or anything.  What the heck do i do now lol :P   Its parked on a slight incline so im scared to jack the car up, is it safe enough to drive it 10ft into my garage or is that going to mess up the brakes.

10ft won't kill anything.
Only thing that will get killed is YOU if you lift it up on an incline.  ;)

When safe, pull the wheels off, then grab the ebrake arm on each caliper with a pair of vise grips - move them back towards the rear of the car - that should release them.

Now, you get to figure out if the cable(s) seized, or the caliper(s).

ya ive already moved it into the garage and got it jacked up, but i ran into another snag. It has those locking nuts, but no key. So im headed down to pick up a 20mm socket to hammer on there and brake them off...  Ive pretty much narrowed the problem down to the calipers, the cables in the rear are slack, as is the one that goes to the handle. So, first thing is to take the rims off, then im just going to replace the rear calipers and cables.  I got a replacement car for the week so thankfully im not under a time crunch, but i need a walkthrough on how to bleed the brakes. Im asking on fiero.nl aswell but id like your guys feedback too. Thanks

Ya I am too, LOL. :)

Check out my rebuild thread to see my status. :)

As for your calipers, congrats on getting the wheels off.

Best bet for bleeding is get a buddy to help you.   You open the bleeder valve, have them push the pedal down slowly, then you close the bleeder valve and they lift up the brake pedal. Do this about 5 times per wheel and you should be good to go.

thanks, that helps.  Now, how do i go about getting the calipers off?  The problem doesn't seem to be the cable, its not seized and the spring is not contracted so im thinking its just the calipers that seized. Any good way of getting them off of there?  A step by step walkthrough would help (ie// clamp blah off, then remove blah  etc..). It'd help if you didn't say blah though, that is pretty vague. :)

edit: ya it was a nice day to be working on the car, not as much fun laying on a cement floor when its cold out lol :P  Sad part of all this is that before it siezed, i spent 3-4 hours cleaning and waxing her in preperation for a nice cruise. Put the ebrake on, went inside to get cleaned up, go out and find this mess lol :P  On the bright side, she'll still be all pretty when i get the brakes fixed. I get sad when i go into the garage and see her up on the jackstands with the paint looking so nice :(

Pick up some line clamps if you dont have any - they're cheap (Can Tire, etc - the Lisle ones are good).  You slip one over each rubber brake line, then twist them down.  Saves you loosing all your brake fluid when you pull the line off.  You'll still loose some - but far less of a mess.

Yank Wheel.
Reef arm of ebrake over, and unhook the cable.
CAREFULLY remove the spring.
CLEAN the area around the banjo fitting.
Crack off the hydraulic line (the banjo).
Stuff it in a baggie, and zip tie or whatever it on.
Use a (T45? T50?) Torx bit, and undo the two bolts holding it onto the bracket.
Now...  if your rotors aren't rusty around the edge, you SHOULD just be able to  slide them off the rotor.  If not, you might need to get various weapons in there to pry them off.  Your pads might get sacrificed.

Install is pretty much the reverse.  If your pads aren't perfect, get new ones.  If your rotors are crappy...  you guessed it...  time to grab a new set.  This isn't a place to cheap out on!!!!!

Prefill the calipers through the hole after they're installed.  Pop the top off your master cylinder. Crack off the line clamp, and let the fluid dribble until you get like 5-10 tablespoons or so.  Quickly stuff the bolt into the banjo (use NEW copper washers! one on each side of the banjo!) and bolt the line down.  Don't strip the hole in the nice new caliper. Let it weep a bit more, then tighten the bolt down (don't go nuts), while wiggling the line/banjo.

Do that to both sides.  IF you're lucky (hey, it happens!) you won't even have to bleed them.

Apply the Ebrake about 20 times (full stroke on/off) to settle the pads.

Now gently apply the brake pedal on/off a few times.
The first few bleed off the vacuum reservoir.
The pedal SHOULD now be hard to press.  About 1.5" or so max movement.  Much more, or if it feels mushy....  oh well...  bleed 'em.

Awesome thanks!  My rotors are rusty around the edges, but my brake pads are due to be changed anyhow so oh well.   Can anyone suggest a good place to get the parts ill need?  Lordco is ok, i get a good discount with my dads government discount thing, but ive found things that i bought there were actually cheaper at canadian tire. Where do you guys shop mostly?   Oh, and will i be needing a torque wrench?  What all will i need?  Calipers (obviously), clamps, brake fluid...

Lordco is 99$ each caliper with a 40 core charge each.  (there will be no core if you bring in your old calipers when you buy the new ones.

ok im stuck here. I got the spring and cable off just fine, undid the fluid line after clamping it off, and undid the screw holding it onto the bracket.  Now, Is there more bolts holding the actual caliper in place or is it just really stuck lol :P  Would opening the bleeder valve while i reef it off help relieve the pressure?  any tips for how i can pry it apart?

If you've got both of the long torx bolts out - that's it.

You can stuff a strong screwdriver (etc) inbetween the rotor and the caliper, and pry up.  Alternate ends - sometimes helps.

I think you're stabbing in the wrong area...

These will be 2 (both the same) large round headed Torx bolts.  They'll use a T45 or 50 to get them out, and they're rather long.

Hmm, ill take a picture because i see 2 similar things that arn't bolts, there rubber things. I thought they would be covering the bolts in question but they wont budge. Ill put some penetrating oil on them and try to pull em off.
