My 'Bird's been off the road for about a year, but I now have it almost in running condition. One problem is that when I hit the break pedal, there's what seems to my foot to be normal pressure on the pedal, but I really have to stomp on it to stop. Is that air in the lines, or is something else weird? I know I have vacuum going to the break booster, but could the booster itself be shot? Or is it air in the break lines and i need to bleed them? The front pads have only a couple hundred miles of highway on them, so I know they're fine, and the rears aren't that old. And the breaks worked OK before I put the car in the garage to put the new engine in.

If the pedals are soft or very easy to hit the back plate then you have air in the lines. Brakes should have a firm to hard feel to them... bleed the brakes and check the fluid level.

 

Maybe you didn't read what I said. It's not easy to hit the breaks to the floor. There is pressure on the pedal, as if they're working normally.

 

me bad ... sorry about that.

I don't know what type of braking system you have but this page should help you narrow the problem.
