| He/am2/AD6.11.29 contd. -5- should be used as previously outlined. Future Cars. That the rear foot brake area should be twice that of the hand brake as on the 20 HP. That all liners should be made .375 thick and that provision should be made for adjustment so that they can be worn down to .180 thick before re-lining is required. With the present material we believe that even then the drums will out-last the lining. He/Ru. | ||
