Post subject:  Tin Brake/Clutch Master Cylinders.

Having not delved into tin master cylinders in many years, what is the difference in the internal makeup of a clutch master cylinder to a brake unit? I seem to remember one had a small one way valve in it to leave some residual pressure in the brake lines? Am I right or is my mind starting to go to mush.

probably starting to go to mush, but it's still right - there is a valve in the brake one, but it's not necessary (according to Doc :D), just makes it easier to bleed them. I went through my big pile of MC's one day, and only 1 of them had the valve in it

Thats cause the rest were Clutch MCs :roll:

Cool, I remember seeing that valve, but couldn't find them in mine either. So it just retards the return a tiny amount?

And bleeding is a very good reason too.

Is there a difference between MCs for disc braked cars vs. drums, aside from the reservoir size?

I seem to remember reading somewhere about the one-way valve in the drum MC needing to be removed when converting to discs, otherwise the caliper pistons don't retract.

I've seen that on other drum conversions where there is a valve to keep a residual pressure in the lines for non-self generating drums.

But as for minis, I dunno..
