| Hs.{Lord Ernest Hives - Chair} X8360 ? X7360 Mxl/T25.1.29 re Phantom Rear Brakes. With reference to your Hs{Lord Ernest Hives - Chair}2/IG19.1.29. We do not have any trouble with the rear brakes due to mud getting in, on all examined the internal mechanism has been quite satisfactory in this respect. We do occasionally after an exceptionally muddy chassis has been washed down find the drums rubbing on the shield, due to mud between, but this soon wears off.
