M35A3 soft brakes

[BIVONA]

I recently purchased am M35A3 ...I am new to this style of trucks ,but not large trucks in general.I drive trucks that have air brake systems.The system on this truck has a soft feel to it(deep depression before they engage) is this common for this type of truck/system?

Yes I was told once the air pressure builds to 90/100+ pounds ,the air assist will help in stearing ..put I am not familiar with air/hydraulic systems...breaks....since this is my first deuce.Any advice on how to remedy the "soft" feel?Could this be a simple fix such as just replacing the break pads?

Did you check the master cylinder for fluid? There are a bunch of threads. I had bled mine it did wonders. Dot 5 fluid

I break air at about 30 psi cause I'm so old. As for my truck, I have air over hydraulic brakes that occasionally break but that the breaks.

The A3's have a split brake system (duel master cylinders)

The soft feel could be it needs bleeding or the brakes need adjusting or possibly more extensive brake service .
