My 85 carrera just came back from 2 great days at Sebring- thanks PCA!!
Throughout the event I lost about 1/4 of the reservoir of brakefluid. I had a few drips on the ground underneath the front drivers area- right where the overflow tube is, but didn't think that was it. Everything else checks out- calipers dry, no fluid around MC, good brakes throughout. When I was tech-ing my car after the event, it is clear that a good deal of brake fluid came out the overflow tube, and coated the underside of the car.
Now I know I am a "GREAT" driver, and can pull many more G's than my car was designed for- yeah right. We were pushing it pretty good, this old car holds its own (especially for an everyday driver) in the instructor group, but nothing more than every other car out there. Is it normal to drain this much brakefluid out the overflow- maybe that is what it is for, but I don't see others with the problem. I fill the reservoir basically up to the top- to the top seam--am I overfilling it?? Is there sometype of valve or anything in the overflow system? Should I just clamp it off when I am at the track? Can I reroute the overflow tube someway, maybe looping it above the reservoir ?
Thanks for any help here- want to go fast, but more want to stay safe.
