I did it, Put DOT 5 silicone fluid in my new brakes Options

[worn]

The car is pretty much a lot of new. Rebuilt engine and transmission, a lot of reddish steel replaced by grey galvaneal. New rotors, calipers, shocks, master cylinder, new windscreen. New silver paint. So, this was the perfect opportunity. As background, my TR6 has run silicone hydraulics, brake and clutch for almost twenty years. That is simply the accepted way of doing things in the LBC world. The TR6 was a sales and sometimes race competitor with the 914, so why not? I have enough toy cars that annual brake bleeding is a PITA, yet since I am the person rebuilding cylinders the idea that rust doesn’t sleep comes to mind.

So I put in DOT 5 silicone in the completely new system. Pedal went straight to the floor. Belly pan off to find that a grommet had come loose and all the fluid leaked out.

My normal 914 practice is to bleed the breaks and drive a bit and then bleed them again. That produced a very firm pedal and spraying gravel. Yeah, I still haven’t taken the car out on the freeway in traffic, but now I am not afraid to try. So far, so good. That will leave only four toys for annual testing moisture content and bleeding through new fluid. Time after time.

I will keep you posted.
