X7480 X5360 V7360 20 HP. for 10,000 Mile Test. REAR BRAKE SHOE LININGSt We wish to increase the thickness of the Ferodo lining on the rear brake shoes from .312 to .375. We suggest this should be done by reducing the depth of the aluminium tube .062, thickening the top flange slightly more than .030.
