Not trying to hijack the thread, but I wonder if that is what I'm having for a problem, only in reverse... when I step on the brake, there is a delay before they really grab... I'll be driving, step on the brakes, feel a bit of drag, then finally the brakes kick in... I just finished replacing the front calipers, rotors, and pads, and the left rear wheel cylinder, (going to do the right one soon too, just so they are all new).. all this time I was thinking it would be my master cylinder, which is a very pricey fix... one which I don't want to do...

Default delay

Delay when stopping could be a similar problem or air in lines, maybe even pads not seating properly or rear shoes out of adjustment.
Best thing to do is take each wheel step by step.

The way it feels is that the back brakes start grabbing, then the fronts kick in.. the wheel doesn't pull either way, and I can do fast stops... Thats why I think it might be corroded rubber brake lines, similar to cactusdoug'* problem...

You really don't want to risk eating another set of pads / rotors. Its not worth it.
If its stuck get a replacement.
New calipers, pads and rotors

I'm in agreement on the lines. Recently changed both sides on my sisters car. Same issue. Lines were about $12 each side.

12 bucks each... OUCH!
I paid $19.95 for the right and $21.95 for the left at Pep Boys.

I'm going over to my neighbors later this afternoon to install them, I'll let you know how it turns out.

OK guys...

Got the new brake lines installed and everything is working great.

I couldn't be happier.

Thanx for all your help.

I hope this teaches all you "Younglings" a lesson. If you have never changed your brake lines, or if you don't know if the brake lines on your vehicles were ever changed, I would get the car on Jack Stands this weekend and thoroughly inspect the front brake lines for ANY cracks or signs of wear. It'* really cheap insurance to replace these lines. You will sleep great at night and your brakes will feel better in the morning.

Great you were able to fix it with new brake hoses. I recently installed new rear hoses, because the old ones were just unsafe. The brakes even felt a bit better!

But like i said, there is that bracket that attaches to the strut, which does corrode, and while corroding, clamping the brake lines, so the front brakes overheat or stick. Its a very common problem on all old cars. Usually what I do, is spread that bracket apart, to losen the clamping of the hose, and it works good. Lines should be replaced though, if any cracking is apparent.
