Note: The majority of the text is a mirrored carbon copy bleeding through from the reverse side of the page and appears to be a report on brake lining tests, unrelated to the drawing. A partial transcription is as follows: ...to gain long life is essential as the breaks are of necessity small. The brakes on one 'Eagle' car were lined with 'Telamite' brake lining and put on severe road test. The brakes on this car were at first adjusted to give maximum braking effect, and when the drums were hot... After 500 miles running the brakes began to drag and this was put down to the drums expanding when hot and... the extra leverage for the work put upon it. The test therefore seems to point to the fact that... The fact that no trouble of this nature has been experienced on the '20 H.P.' car is due to the larger brake drums used. | ||
