| Yep, thanks Cardinal, accepted that green is available for manual braking at this point.
The only bit I'm not 100% about is whether the yellow pressure is trapped and the brake stays on once yellow system is depressurised as I've not seen that written down anywhere as such. Manuals suggest that the park brake will stay applied for 12 hours if the system is within leak tolerances but that presumes I suppose that the accumulator is good.
I guess it would be a rare occurence to have an accumulator failure anyway. |
