Hello everybody.
Now I'm getting this kind of the problem.
It takes more and more time and pressure to fill the tanks that are responsible
for retracting the parking brakes.
The control light doesn't even come off.
So what was the solution - servicing that 4 way gizmo ?
Chas did you find the problem ?

I'll do that.Thank you.

The control light goes off but after a while.
I can hear the air filling the cylinders when I release parking brake,
but it's not as rapid as used to be.
I didn't touch $ way valve yet.
Hopefully tomorrow.

Dirty minds...

Question about taking out 4 way valve.
I tried to use a 28mm flat wrench and stripped one of the brass fitting edges.
I stopped there, and decided to use flare nut wrench.
Problem is I can't find that size of flare nut wrench.
What are other non destructive ways of disconnecting those 7 lines that run to that valve ??

EDIT

It's 24mm not 28mm.

Metric Adapters

Me again.

Anybody knows where to find metric adapters like these?

I need 22mm/1.5mm Female to 16mm/1.5mm Male
and 18mm/1.5mm Male to 16mm/1.5mm Male.

Preferably in Canada.
