Can't find a brake fluid leak just below the master cylinder of my 1994 Corvette Coupe. Just finished checking the brake lines, hoses ad master cylinder without success. A few months ago, I was getting brake residue leaking from around the brake reservior cap. The brake fluid reservior appears to be dry now. Can anyone recommend other areas to check or the cause of this mystery brake fluid leak.

It is possible to have a pinhole leak in one of the lines. Check them real closely. use flour and a hobby brush to locate any wet spots....Good luck.

It appears that the brake fluid leak is coming from whats called "high pressure sensor." I purchase a new sensor, cleaned out the fitting hole, installd sensor and it still leaking brake fluid when I apply pressure to the brake pedal. Any ideal whats the problem with the master cylinder. Has anyone experienced the same problem with C-4 Corvette Coupe. I desperate for answers!

I had a myterious leak in my 84... it was the brake light switch sensor... look on side the master cylinder and you'll see wires going to it... unplug them and see if there is fluid coming from there.
