Hi Arthur...

If I am not mistaken, you cannot introduce pressurized air into the
M35's brake system at any point to apply the hydraulic service brakes.

As we all know, the brakes on the M35 are not "air brakes", but rather
they are air-assisted hydraulic brakes. Just like a passenger car
which is vaccuum-assisted brakes...you could not introduce a vacuum to
actually apply the brakes.

So I think you would have to put pressure on the hydraulic system...so
the best you could do on the dash to hold the brakes on is use a
"Mico" system.

But I could be wrong. ;)
