Silicone/DOT5 seal incompatibility is b.s. plain and simple. Bout six or seven years ago, harley switched from DOT5 to 4. The part number for the master cylinder changed but nothing else did.
Why?
Because the master cylinder LABEL changed. ALL internal parts remain the same. AND now their paint on their master cylinders bubble and peel.
I like how rusty states his unfounded fears without any shred of proof, empirical or otherwise, and rolls out. That's what makes the world go round!
I guess he never used the seal lube that comes in a rebuild kit..... it's silicone!
