{"product_id":"brake-shoes-pa4707","title":"Brake Shoes PA4707 \/ FMSI 4707 - 16.5\" x 7\" Q-Plus S-Cam Heavy-Duty","description":"\u003cp\u003eA loaded Class 8 tractor coming down a five-percent grade carries roughly eight hundred thousand foot-pounds of kinetic energy. The friction surfaces inside its drum brakes turn most of that energy into heat in under a minute. Q-Plus is the FMSI designation for the friction grade engineered for that duty cycle, the one that holds rated coefficient under sustained 800°F drum temperature without fading and without glazing. The PA4707 is the 16.5 by 7 inch shoe assembly built to that grade, the size you see on virtually every air-brake S-Cam axle currently in service on a North American highway tractor or trailer.\u003c\/p\u003e\n\n\u003ch2\u003eFits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e16.5\" x 7\" S-Cam air brake systems\u003c\/li\u003e\n\u003cli\u003eClass 8 tractor steer and drive axles\u003c\/li\u003e\n\u003cli\u003eHeavy-duty trailers with S-Cam actuation\u003c\/li\u003e\n\u003cli\u003eFMSI designation: 4707 (Q-Plus friction grade)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCross-Reference\u003c\/h2\u003e\n\u003cp\u003eThe PA4707 carries the FMSI 4707 reference number, which is the multi-make industry standard for this shoe geometry.
