| X264a HOTEL DE FRANCE, CHATEAUROUX, Indre. France. 12th May 1936. GWH{George W. Hancock - Head Chateauroux}/5/JAB. To. Hs.{Lord Ernest Hives - Chair} From. G.W.H. B.56.BN.{W.O. Bentley / Mr Barrington} - BENTLEY. Front brake jaggers were again experienced during the run from Lyons to Châteauroux as reported to you yesterday the 11th. Upon investigating for a reason for the jagger especially the O.S.F. after having made the front axle control solid, we found the following. There was no adjustment left on this brake. The following ball pins and levers were bent:- Bottom lever GB 1255/6 twisted in the neck, and ball pin bent in the neck on load side. Top brake actuating lever on toggle shaft, ball pin bent in the neck on load side. The twisting and bending of these parts takes all adjustment from the brake. The two plain pins that hold the brake toggles GB 1835 bent in the centre, we had difficulty in getting these out, to dismantle the shoes. The toggles did not bend on this occasion. The N.S.F. bottom lever GB 1255/6 was twisted and ball pin bent in the neck. Top lever O.K. toggle pins bent in centre same as O.S. We have fitted two bottom levers G 101164/5 taken off a previous axle we had here. The difference in these levers is, they have a kink not straight as the GB.1255. Why we do not know, as these levers do not foul the axle end during operation. They are stronger levers and do not look as if they would bend so readily as apparently the GB.1255/6 do. The ball pins must be made of too soft a material. ---------- G.W.H. | ||
