hehe, just did that a few weeks ago freejeep! I posted a thread called, "im loosing faith."
Its not bad at all. I had alittle trouble getting the caliper off since it was seized up, but a good sized screw driver brought it off.. Make sure you remember that it hinges at the top and swings out from the bottom. I was giving it all I had trying to get the top out..
Bleeding the brakes it nothing special. Make sure that you do not let the brake fluid reservoir go empty before you get the new caliper on. I had to take min off and leave it over night so that was a problem.. It may not be for you. If you did, you would need to bleed all four calipers..
After you get the new caliper on, go ahead and fill the fluid up to the rim and MAKE sure it doesnt go empty. Get someone to pump the brakes up(3-4times or until hard), then HOLD. Loosen the bleeder screw up while they push the pedal to the floor and HOLD it to the floor. Tighten the bleeder screw back up and tell them to pump them again. Do that until teh pedal feels firm or until you do not see air coming out of the bleeder screw again. A good piece of hose makes this job ALOT easier.
I ended up doing that around 5-6 times and my brake still seem alittle soft. Whenever I get a chance, Im going to go ahead and bleed the other 3 calipers..
Hope this helps freejeep..
Ohh, I got mine for $62 at Napa with a core.. I believe it was $9X before the core..
