[Tigers] FW: Brake Issue

[Joe Brown]

Well, I'm ashamed to admit that I cheaped out and bought my master cylinder
from a cheap source a couple of years ago and I'm just now trying to use
it. The brake pedal comes back up and everything feels good.  But somebody
mentioned it might have a check valve.

I'll rip it apart tomorrow and see if I can figure it out. I'll probably be
ordering a new one from Sunbeam Specialties to make sure I get a good one.

Thanks for all of the responses.

Joe
