Its a fecking joke if you ask me,
I remember Maurice had to get new brake shoes 5 years on the trot because of the Handbrake failing by something stupid like 1%
Think Jack had some issue also which was silly ,
That's a perennial problem. The handbrake on a Ducato is not a handbrake, it's a parking brake only to be applied after the vehicle has stopped to prevent it rolling away.
Applying it while the wheels are in motion will cause it to snatch, it therefore jumps out of the test rollers before a valid reading is registered.
The only way to get anything close to a valid reading is for the tester to very slowly apply the brake to prevent it snatching.
