Massey air brakes

[Baz65]

Does anyone know if this as a service seal kit available, local Massey dealers says no and doesn't have an exploded parts diagram.
ours doesn't release trailer brakes when handbrake is released, and is leaking air when the handbrake is off.
it's on a Massey 7618 Dyna VT

I dont know if a service kit is available but cant imagine theres much in there that cant be matched up in a half decent stockists

That's called a fluid reaction valve if it help you look.

Has yours got a cable connected to the handbrake? On a older NH they used a cable to put the handbrake on however on anything from 2007 onwards there's a separate electric solenoid to release the handbrake. Theres also a diaphragm that goes in one of the relay valves, we've had a couple go this year.

The majority of the air brake parts are Wabco, if you go to your local truck parts place you can generally pick up the bits for 1/3 of the price.

There's a linkage that connects to the handbrake, from what I can make out is that on the righthand side is connected to the footbrake hydraulic line, and the left-hand side is the air with a piston in between.
Trailer brakes work via peddle but handbrake doesn't apply trailer brakes.
I'll have a look via truck parts site.

Cheers Baz

Ours used too, could do with a exploded diagram to see what’s inside, there’s no makers plate on it so no idea who makes them.

This black part connects to the handbrake mechanism, it leaks air, the threaded screw it rotates on has a slot for a screw driver.

That's the same valve they used to fit onto TM's.

Update took the valve apart today all that is in it is 3 ball bearings and o-ring. The grease that lubricates the ball bearings and O-ring had dried so sprayed it with silicone grease, put it back together. Started tractor up built air pressure up. No air leek and when you release handbrake it dumps the air as it should. Job done . Glad I didn't get dealer to look at it as I think they would have fitted new valve @ approximately £1200.
