Brake Fluid Types in Aluminum Bores
I have some buddies that have used the side mount system you are looking at with no issues as long as you can remove your dash to access the MC. one issue we did come across was corrosion and aluminum wear in the bore. He was using a DOT 3 standard brake fluid and we changed to a DOT 5 Synthetic fluid (silicon). This resolved the moisture issue (corrosion) and hopefully the aluminum wear issue to a degree. You will need to flush an existing system out to convert to the DOT 5 fluid.
