| 8769. Expl. Dept. Hs{Lord Ernest Hives - Chair}/GMH.7/KT. 20th April 1931. Messrs Ferodo Ltd. Sovereign Mills, Chapel-en-Frith. For the attention of Mr. Longley. Dear Sir, We have completed our tests with the new brake lining you sent us to try. The results are disappointing, the squeak came on after Approx. 500 miles and is now consistent with the brakes cold and hot. The squeak is a higher note than with previous linings. The efficiency of the linings compared with our present standard is approx. the same. Yours faithfully, For Rolls-Royce Ltd. | ||
