Re: my brake pedal doesn't return to normal (Zinc)
Check your connection at your vacume Booster, this is what your master cylinder connects to. With the car running look at the vacume line that run to the booster, check it for a leak , if it is leaking you will hear It. Does the car stop or is the pedal just going to the floor and you don't have any brakes. Does your car have ABS? Which light is on the red brake light or the amber ABS light or both. Both lights should come on when you start the car letting you know the ABS ( if equiped ) is working. Check the Brake fluid, add if needed ( but only DOT 4 ). Look at the fluid with a flash light and see if you have any oil bubbles from contamination. Do you have any Brake fluid on your driveway? We need to know more details to help you with your problem, from what you put in your post it sounds like the vacume booster, but there are too many unknowns to give you a correct answer.
