It's been a long time since I bled brakes on a 164 - maybe 20 years.
I used a home made pressure bleeder which amounted to a cap with an air fitting double-nutted
to it and pressurizing the reservoir at about 30 psi.
As I recall the fluid came out pretty fast.
Working on the Mroon 164E, sitting since 2004, first time I tried the brakes the pedal went
to the floor and the exhaust emitted a large white cloud.
Identifying this as a bad MC rear seal, I bench bled the new MC as best I could and installed it
after taking nearly a quart of brake fluid out of the booster body. The pedal still went to the floor.
So I hooked up my pressure bleeder (after buying and installing a new regulator on my compressor)
and tried again. No fast bleeding from any bleeder valve, in fact no fluid from any valve except
the top ones on the front calipers, and they only dripped slowly. The rest seemed dry.
I increased the pressure from 20 psi to 30 psi - same result.
I am sure things are stopped up somewhere but am not sure where to start.
I probably should buy all new hoses based on my knowledge that these swell shut,
but would like to minimize diagnostic time. Should I disconnect hoses and gradually
pressurize the system a bit to see what drips and what doesn't?
Is it likely the calipers themselves are stopped up?
Results of any experience more recent than mine would be most welcome!
