Brake caliper dust boots, Major screw-up Options

[computers4kids]

I decided to freshen the brakes up on a 75 that I had picked-up. The brake pads were shot but the brakes worked well and the calipers didn't leak. OK...this should be an easy one...right.

Leaving the calipers brake lines connected, I unbolted all four calipers and removed the brake pads. Installed the first rear caliper with new pads and was making the clearance adjustments...this is where the "oh shit" part comes in. Not thinking I decided to pump the brakes a few times to see how the adjustment went on that first rear wheel.

Yup...got out of the car an saw pools of fluid below the other three calipers....I had fully extended the pistons and two of the calipers ripped the dust boots, but all three shot fluid out once the piston came to the end of its travel.

So what are my choices at this point?
I pushed the pistons back in on all three calipers, but a front and rear caliper tore it's dust boot (I think that's what it's called)?

What's involved in replacing those dust boot seals? I presume those seals are to protect the pistons from dust and are not the seals that actually seal the fluid in the brake cylinder? If they don't seal fluid, how critical are non torn dust boots?

This is the dumbest thing Ive ever done (IMG:style_emoticons/default/headbang.gif)
