Default brake problem

I have to keep bleeding my brakes on my 81. I replaced the master a while back. I also can smell brake fluid under the hood after a long ride.I can't see aany leaks and now the car pulls to the left when I step on the Brakes. Any suggestions before I replace the front calipers.Thanks..MIKE

If you can smell brake fluid under the hood, maybe your master cyl is leaking into the booster? How much fluid does it go through?

Default Warped Rotor ?

You should check your rotors for run out. If a rotor is warped it will cause the piston to suck air in past the lip seal.

You say you're not leaking fluid, but if you can smell it, it's coming out somewhere. Start following all the lines on down to each caliper and find out where it's leaking. It could be very slightly leaking at a caliper piston but not enough to show anything on the floor. Pull those front wheels and start checking until you find the source of your fluid smell. Good luck!

The right caliper isn't braking as effectively as the left. Most likely it isn't working but it could also be dragging and the brake could be fading from the heat.

I have a pull to the right upon braking and have checked numerious things - including alignment, sticking and/or leaking calipers, bled the system numerious times, contaminated pads . I assume a "bad" rear caliper could cause a pull too. I'm interested to see where your problem is.

Did you check the pads? Are they dry?

if you smell the brake fluid under the hood and not out at the wheels - check the proportioning valve (on the frame, under the brake m/c) for leaks.

Many times a pull to one side or the other is due to the rubber hoses swelling shut on the inside. They will look good on the outside but can be collapsed. If it pulls left then the right hose may be the culprit.

Patience, my friend. Corvettes require, no, demand it. They can be your best friend or worst enemy. You have a leak somewhere and it should not be too difficult to find. You have received good advice here.

If you are sure the master cylinder is good (the seal around the cap and the MC itself), then start from there and follow the lines out through the proportioning valve to each front wheel. Check the hard lines at the proportioning valve and out to the flexible hoses. Check the hoses at each wheel. Check the brake pads. If they are wet or simply damp looking your caliper is leaking around the piston seals. Remove and replace with new or rebuilt parts and fresh pads. There isn't much left to look at.

Just for grins and giggles, pull the big vacuum hose loose at the brake booster and see if it is oily inside. Even a fresh MC could have a leaky or damaged seal.

Good luck!
