To Wor.{Arthur Wormald - General Works Manager} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}

Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}9/KW.17.12.34.

Juddering Brakes.

B-122-CR.{Mr Cra???ster / Mr Chichester} Mrs. Geoffrey Duveen.
B-129-AE. Mr. Geoffrey Duveen.
B-136-AH. Mr. W.L.P. Miesagaes.

The results of the work done at Kingsbury on these three customers' cars showed that the judders they were experiencing could not be cured by attention to the brake bedding. We consider that these cars were representative of the particular complaint.

Before saying that we can do nothing further we want to try Ferodo Bonded Asbestos front brake liners and an improved water excluder scheme. We are not quite ready with the water exclusion scheme, but recommend that the Ferodo Bonded Asbestos liners should be fitted to Rippon's car when it comes here on Tuesday.
