| Wor{Arthur Wormald - General Works Manager}/lly9/L17814. Sheet 3. Raybestos until we have evolved a brake which will work with Ferodo as the effects with all these heat insulating fabrics will be the same, the only point to be decided being their ability to withstand wear. A noticeable thing about these stationary brake tests is that the near side brake has evidently done more work than the off side in every case. This may be due to the reaction of the engine driving. | ||
