Soft breaks on dp
I have a 2013 holiday rambler ambassador that gives me what I consider "soft breaks". In other words it takes maximum foot pressure when coming off the Interstate or up to a red light to stop the unit...

That's a tough break about your brakes. ;-)
Yes, definitely get your air pressure up. One other thing nobody's mentioned is that when you press on the brake pedal, you aren't really pushing against the 65 PSI or even the 110 PSI once you get it fixed. Air brakes are not the same as hydraulic brakes where you create the pressure in the fluid with your foot.
When you press the foot pedal, it opens up the primary circuit that opens up the valve to the rear brakes and when you press further, it opens up the valve for the secondary circuit (front brakes). The further you press, the more pressure should be applied to the brakes, but it's not your foot creating the brake pressure, it's the air system.
The brake pedal acts mostly like an on/off switch except that every time you push further, you turn it on again. If you hold the brake in position, you reach a balance state where the brakes hold their position. If you push further, it turns on the air flow again (pushing the actuator rod further) until you reach balance again. When you take your foot off the brakes, the quick release valves open to release all air from the brakes and prevent brake drag.
The pressure you feel when you press on the brakes is only because of the spring behind the pedal. It is not an indication of how much force you are applying to the brakes.
