I think you have other issues than a bad vacuum-pump.

The vacuum pod may very well be bad, but I don't think that is your only issue.

Poor vacuum will usually do the reverse and make the pedal nigh impossible to push to the floor, even push the pedal back upwards at you.


It reads like you have a hydraulic issue going on.

 

It's not I have bled the brakes for 3 hours a couple days ago new master cylinder the brakes will lock the tires the peddle just sinks to the floor slowly but if I keep the rpm's about 1000 n push the brake peddle it won't sink till I let off the throttle n the vacuum comes down a few pounds.

 

That reads more like a bypassing master-cylinder or a leak in the hydraulics somewhere.

Vacuum or no, the pedal should remain firm.


Vacuum is measured in inches-HG, no pounds involved.

 

I replaced my master cylinder a few days ago with a brand new one it works fine I don't have any leaks either I was over the brake system a dozen times.

I fixed my problem temporarily till I know what is going on with workers compensation. I made a vacuum canister n I have firm brakes now.
