Ok, this is my first attempt at any brake work, and it will probably show... Anyhoo, I've got a 1990 Fleetwood (4.5 FWD blah blah blah), it does not have the heavy duty brake package that was an option...and it does have abs and anti-lock, if that comes into play. Anyway, thanks to the indicator busting, I had no idea until recently that my left front wheel had eaten almost one entire side of a rotor, and the pad as well...so I got rotors and pads... No problem getting stuff off...I un-mounted the caliper and put the new pads on, and to my dismay, I discovered that with the caliper piston in its current position, there was nowhere near enough room between them to put it back over the destroyed rotor, let alone the new one. I'm just a little uneasy about forcing things, and am unsure how I should get that piston back where it belongs...so if someone could point me in the right direction, I'd be most grateful .

Re: Little disc brake help...
For front brake calipers, you have to press the piston back in. What you do, is put an old brake pad in the caliper against the piston. Using either a C-clamp, or a brake piston clamp (which I use), you reset the piston back into the caliper. You will have to remove the master cylinder cap, and any excess fluid, so the fluid that is being pushed back through the lines, doesn't cause an overflow situation. Also, just in case you don't know this, DO NOT GET DOT3 BRAKE FLUID ON ANY PAINTED SURFACES. The brake fluid will liquify, and destroy the paint.
