Been a while since I have been on here, but having an issue with my brakes so coming to the best minds to try and resolve the issue. Here is my set up:
- 280zx Front Disc
280zx rear disc
15/16 Master Cylinder
After this I noticed some fluid on my transmission, turned out to be brake fluid and it was coming from the hard line that runs down the tranny tunnel to the rear. I assume it had a crack so I replaced it with a soft stainless steel braided line. After replacing this line I decided to get a vacuum bleed system. Continued to bleed the brakes as recommended(RR,LF,FR,FL) with the vacuum pump, same problem still persists. I checked the entire system and I do not see any visible leaks. I even did a "bench bleed" of the MC while in the car using the side ports and hose redirecting to the reservoirs and still the same problem is there.
The Problem : No pressure when first applying pressure. Give it 3 pumps and it has what I would consider somewhere between 1/2 and 3/4 pressure of what it has been in the past. This pressure will hold, I tested by putting a 2x4 against the pedal and seat and it stayed in place for over an hour.
