I just finished a new engine install with a cam similar to the cc503. I also installed stainless brake lines and powdercoated calipers. oiled up all the pins and pads good and bleed the lines of air twice.

Now.. when driving the car when I hit the brakes it does nothing.. all the way to the floor.. Nothing. I pump it a second time and starts to slowly slow the car down, the 3rd full pump slows and stops the car normally. So it take me 3 full pumps to get regular stopping power. I don't see any leaks on any lines or calipers and I know the system is air free.

I have a ABS delete - line lock system and a regulator for the rear breaks. I think it might be in locked position so it's not letting any pressure for the front brakes? but who knows I just installed it? Anything else it could be?

 

Well.. think I found the problem. I went to look at the master cylinder and I see this:

 

Yep, that'll do it every time

Time for a new master cylinder.

 

now where do to find a good deal on a new booster and master cylinder?

 

You could get some remanufactured parts from your local auto parts store (usually inferior quality), go to the dealer (expensive), or order them from GM parts direct.

Also try eBay Motors, some venders sell genuine GM parts for discount prices.

 

Actually I've ordered up GM parts from Sam Strano. Good pricing with the stupid high shipping cost of GM parts direct

 

Good call. Didn't realize he carried genuine GM replacement parts.

 

Without the stupid high shipping cost?

What he said

 

bleed the system, that might help

 

Did you see the pic lol??

Bleeding is a waste of time when the master is leaking.

 

I ordered a new acdelco gm oem booster and master cylinder, not reman. They were $350 shipped, hope I did ok.

 

Sounds pretty good to me for brand new AC Delco parts!!
