Can someone point me to the modern replacement for the rear brake relay valve for 4106. It has single circuit brakes.
I was adjusting slack and my helper did a heavy apply and both rear stayed applied. Fronts were retracted but not rears. Cracking a chamber line its still got pressure. Eventually it drains off and chambers retract.
This valve has three mounting holes.
Call Luke at US Coach and it will be on the way with your credit card.
Good catch, finding that lazy relay valve!!!
Happy coaching!

DD-3's not releasing? Try a couple more applications.

Didn't think that the 4106 had DD3 brakes. Have these been changed?

Richard -DD3 brakes were an option on late production 4106s.

FWIW & HTH. . . ;)

I guess first, how many hoses connected to each brake chamber? Two or three? Can't see from here.
How did this stray onto DD3?
OP has identified a lazy releasing relay valve, and said it has 3 mounting holes...
Winter fever is setting in...
Happy coaching!

yes they do and both type chambers use same relay valves, possibly different model. mine uses r6
