Residual Valve?

[kittypancake]

Okay...I'm thinking the equal reservoir maybe the right one...if there is no residual valve in the rear port

How do I check for a residual valve without destroying the tube seat?

You don't.

You don't.

bad news...but good to know

You don't.

I thought there may be a way to test pressure, but I didn't know for sure

I can't seem to find it, but I remember 7-12PSI being the amt. the valve would hold in the line to keep the wheel cyl. cups tight against the bore, preventing air/moisture
from entering on cool-down. I guess a Teed-in gauge reading much of anything over -0- would say yes. The '74 FSM stated that tandem M/Cyls. did not use residual check
valves because they switched to the spring-loaded cup supports in the wheel cyls. The only M/cyl w/one was 1ton tks/vans, anyone with more intimate knowledge can jump
in and correct me if this is not correct. I'm sure the aluminum late model RWD units are sans residual check valves.
