FILTON HOUSE, BRISTOL, ENG. Your Ref. Our Ref. ENGINES F/FTM/38. April 8th, 1935. W.A.Robotham, Esq., Messrs. Rolls-Royce, Ltd., D E R B Y. My dear Robotham, Many thanks for your letter of March 21st, to which I must apologise for not answering before, but I have been away a good deal from the Works. I have been using the car a good deal lately, and I can only tell you the results that I have obtained, which are as follows:- (1). Running the car with the cycle type mud-guards off definitely does not cure brake squealing. As Mr. Sidgreaves put forward this point again, I had this experiment repeated. I find that with the mud-guards off, or insulated with rubber packing, the volume of the screech is lessened, but it is still there and quite objectionable. (2). I have taken the drums off and carefully cleaned out the stuff which collects in the countersunk holes of the rivet of the brake-lining, and, quite definitely, this squealing is absolutely cured. After about 50 or 60 miles, however, the countersunk holes get filled up again, and then the trouble re-commences. It would rather look as if these countersunk holes collect foreign matter which forms into a hard core and produces results rather like a rivet head. You say in your letter that you could deal with the chassis in three weeks' time, which would be this coming week, but I am very badly in want of a car when I do let mine go; I would also like to have the chassis and the body work done at the same time, and with Easter so near I would suggest that I should leave it over until after the holidays. As I take it that the chassis work plus the body work would take a total of 3 weeks, may I send the car to you on April 29th for a week's work at Derby, to be followed up by the modifications to the body and mud-guards, which would take until about May 23rd.? Would it be possible to lend me a car of any sort during the intervening period while my car is away with you at Derby, and at Park Wards? Yours sincerely, | ||
