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
Technician: Wayne, Journeyman replied 1 year ago

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
