Adjusting Vacuum brake?

[Malcolm Towrie]

Thanks, Lynn.

When you say carriers labour a bit turning on soft ground in second gear, do you mean even doing just a "track-twist" turn, or only when doing a "braked" turn? Seemed to me ours laboured in second even doing the track-twist turn.

Would it be correct to adjust the vacuum brake so it just contacts the disk at idle, which I can see by watching the timing light just start to retard? Because the vacuum at idle is up around 20", so at high loads, when the vacuum drops to near zero, the full spring tension will be braking the disk.
