WEAR ON BRAKE MECHANISM. Hancock has pointed out several points which we would like to bring forward in the brake mechanism which have unduly worn. The points are the lug and pin G.52042 connecting brake pedal to operating shaft. Links and pins G.52045 and G.52189 connecting up levers to cams on servo. Lug and pin G.52121 and G.52190 connecting cams to equalising shaft. We think that more bearing surface should be provided for these or that they should be heat treated to withstand the wear that has taken place. We should also like to bring your attention to the bearings of pedals. A considerable amount of wear has taken place in these bearings allowing end play to develop. The end play has a considerable amount to do with the wear of bearings. With this condition, when oiling the bearings, the oil is forced out at the ends, instead of being fed round the bearings, with the result that these are worn out more quickly. A better provision should be made to keep these more oil-tight. Hs.{Lord Ernest Hives - Chair} | ||
