Hi I'm Wayne

I will help you with this

what you are describing may be a brake chamber

leaking back internally

To check this out, block off each parking brake hose 1 at a time

to see if it stops , if yes replace that chamber

I hope this helped you

just remember the tractor is not locking up it keeps rolling but at the same time it leaks air at the foot brake valve

Thank you for that

I still suggest to check brake chambers

it can bleed back with out locking the brakes

if all OK, issue is the the tractor protection valve
