im running a nova on a 1/2 mile track. i changed out the front clip this year and now i have no brakes. i have bleed them and changed master cylinders and still no luck. they build up pressure after rapidly pumping them 12 or 15 times. im also not using a brake booster either. any help would be greatly appreciated. thanks in advance.

I think you have a bad master cyl. If you have pressure then lose it, the fluid must be dripping down your fire wall. First open all the bleeders until they drip fluid, now close them one by one as they start to drip. Now pump the pedal a couple easy pumps and crack each bleeder once or twice. This should take 99% of the air out. Now pump til hard (3 pumps average) and again crack each bleeder. If you still have no pedal, master cly must be bad.

i have tried about 4 different master cylinders ands i know this one is good and it isnt showing any leaks. also when i pump them up 10 or so times and gain pressure it will hold teh pressure as long as i hold the pedal down. i have purged teh system of all the old fluid. it will be this weekend b4 i can mess with my car any, i will try what pickel said and post teh results and i greatly appreciate all your help guys.

Make sure the proportioning valve isn't closing off the front brakes,have someone hold the valve under the car while you bleed them and see if that doesn't help.

Check your front calipers. I had some brackets bend that had the caliper on an angle to the rotor and when you push the brake down, nothing. The caliper would start to straighten out if you pumped the a lot, but once you release them it would spring back and force the caliper open to wide to work on a single pump.
