Aloha All,
I started surveying and repairing or replacing the brake system on a recently acquired TR3A. When removing the master cylinders for the brakes and clutch, I broke one of the fluid pipes between the reservoir and the brake master. I replaced both masters for clutch and brake and fabricated new pipes for each from the reservoir to them. I had a small leak at the connection to each of the masters which only became noticable over time. I thought the problem was the double flares I made on the pipes, so I decided to replace the pipes with factory made flares. I still have the leaks. The problem seems to be the machined mating surface in the masters have small "nicks" that make a tight seal impossible. Is there a tool to smooth these surfaces? Could I use lapping compound and pipe with a good flare to clean them up? As a last resort, I am considering using an O-Ring, since this is not a high pressure line. Any help would be greatly appreciated. This problem is keeping the car off the road where it belongs.
Safety Fast,
Dave
