Anyway, I finally got everything back together and topped up the brake fluid...

Now, the pads won't really set. I have to press the brake pedal 3 times, and on the third they feel fine. The first two are just nothing but air. So, the third works, and then I'll give the car some gas and move, say, 10 feet, and then have to press the brakes 3 times to stop again.

Could I just have a stupidly large amount of air in the brake system and have to bleed them? Could I possibly have damaged the pistons? (I don't think I could have buggered BOTH of them, but I guess it's possible) Aside from the air, I can't really think of what it could be, but I'm pretty much an amateur.

Can anyone give me some ideas to try out?

Thanks a lot.

Maybe i am thinking of a different car, but dont you have to use the E brake to adjust those pistons back out?
