Question about 1994 Chevrolet Corvette

3 Answers

Brakes when I depress the break petal it makes a hissing sound at the break petal area. The stopping power has been reduced, I do have to depress the petal harder to make it stop. I checked the pads and the rear needed replacing which i did and bleed the brakes. Still having the same problem though so I am thinking it could be the break master cylinder or the break booster? I have a 94 chev corvette so both are expensive. I would hate to replace one and find out its the other. Any advise on which it could be would be greatly appreciated

Most likely your vacumn power brake booster has failed. It is not rebuildable. You will need to buy a new one.

Check The Vacuum Going To Your Booster. Remove The Vacuum Line At The Booster While The Car Is Running And Put Your Finger Over The Vacuum Line. If Good Suction Your Vacuum Is Good If Not Theres Your Problem.

Buy a manual and follow the trouble shooting section.
look for oil leaks around master cylinder.
No oil leaks- take a closer look at your vacum lines to the brake booster.
An old engine can loose the ability to produce a good vacum at low Rpm's confirm that your engine is in good condition.

Why would my brakes hiss when I step on them and cause the engine to rev up when I do this? It also makes the vehicle very hard to stop.


It sounds like your brake booster is leaking. The air hissing is the air going into the leak. This extra air goes into the engine and causes the engine to rev up. The booster is what makes it easy to push the brake, (when it is working correctly) which is why the pedal is hard to push.

right, your booster diaphram has torn. You will have to replace the booster. Often this can be done without breaking the hydraulic system open. If you would like to do it yourself, let me know and I will send instructions.

The brake booster is shot, there is a rubber diaphram inside the booster and it must be ruptured and is leaking vacuum. You may want to go to; car-parts.com, to see if the salvage yards in area have a used one.

Brake light on, power brakes seem gone


Chk. for vacume to booster, or loss of vacume like a break in vacume hose, do you hear a hissing noise when you step on break peddel. If you don't hear anything chanses are its the booster. When peddel gets hard to push you either lost vacume or booster went bad.

Air around break petal


It sounds as though the diaphragm on your vacuum assist has ruptured. This will cause a hissing sound and less brake you may also notice a change in the engine idle speed or a rough idle until the hissing stops.
