I think air holds the brake OFF - like in a big truck - and it takes a good
bit of pressure to do that. Not hundreds of pounds, but pretty close to
normal cutoff of many compressors - around 100 psi or more. My compressor
kicks in at slightly more than 85 psi. I have had to manually bleed the
compressor tank a bit to get it to kick in so the BP brake would
function. Seems like the brake will remain disengaged at a lower pressure
than it takes to disengage it from the braking status.
