Rm{William Robotham - Chief Engineer}/GWH{George W. Hancock - Head Chateauroux}/DPB/10.8.37. n v 67 PHANTOM III. Front Brakes. -------------------- Cricklewood have had two cars in this week end with failure of the front brake operating lever G.83302. (Dumb Bell). The fracture has occurred at the neck of the spherical ball in the lever outside the brake drum. The fracture is caused by the quarrelling of the outside lever with the lever inside the brake drum when on full right hand lock of the steering. (Offside lever broken). The flimsy brake stop inside the brake drum is the chief cause, as when this springs out of position, the G.83302 lever is trapped worse between the two levers. The first car to have this failure was 3.AZ.60. (Mr.Raphael) while in France. He had a link turned and fitted locally. This being made of M.S. broke again, but it is interesting in so much that it shews the stresses which is ringing off the spherical end. The second car 3.AZ.84 (Mr.Brandon) broke in England (Mileage 7,000). The failure caused the car to spin round, but no damage was caused. I am sending you the broken links and one damaged. 4 taken out of Cricklewood Stores, which I consider under the circumstances, is a tributary cause for failure.
