Howto determine proper TowV Aire air pressure

[jdr37]

I have just installed a TowV Aire toad brake system on my '02 Saturn L200.
It works perfectly as descrobed in the literature but, following the manufacturer's recommended air pressure setting the weight of my toad (25 psi for 3000 lb toad) I don't feel as tghough I'm getting the braking force I would like to "feel". This is a non-vacumm system.
Although a little different in design layout it appears to function similar to most other non-vacumm air pressure on brake pedal systems.

My question is: what pressure do others with a similar system find to afford the best toad braking without over working the toad brake?

I used a Tow-V-Aire for 6 years and it performed quite well. As I recall, I ran mine at about 38-40 psi on a 3300 lb toad.

If you feel the toad braking, i.e. it is pulling back on the coach, the pressure is too high. You do not want to use the toad brakes to help stop the coach - it should just be stopping itself. Once you feel the toad brake drag, back off the pressure until it stops and then back off some more just to make sure. If the toad brakes start helping stop the coach too, your toad's service brakes will wear out real soon.

Thanks Gary,
Make sense -- I'll give it a try.
