Issue with the brakes!

[HustlerTalon]

Ok so I took my dam talon out for a spin and everything was going ok until I got to a red light and when I went to press the brakes, the damn brakes were so hard to push in (just like the car is turned off, they get really stiff)...however my car is still on and running. It takes all my leg power just to get the car to a complete stop...I had to drive with my hand on the e-brake because I was so scared to run into the car in front of me.

Here is the weird thing, if I drive for say like a minute without touching the brakes, the brakes will work only for the next time I press the brakes. If I let them go, then try to apply the brakes again, the brakes get stiff.

The brake master cylinder was replaced about 2 months ago.

Any ideas???

It sounds like to me the vacuum booster may not be getting vacuum or there is a vacuum leak from it. i would check that vacuum is getting to the booster and pull vacuum on the booster with a vacuum pump.

Is this a recent event long after the master cyl. was replaced? If so the air in the lines is probably out of the running I'd check to make sure the vacuum line didnt come off the booster.

Is that the line that connects to the intake manifold and has a little check valve inside?

Is it getting clogged or leaking?

i say disconect the hose that goes to the brake booster, you should feel vacume, Im thinking you have a bad Booster.

The check valve for the booster is cleverly hidden inside the vacuum line. Whoever did your replacement put the hose on backward. Turn it around.
