This OEM rear brake pad kit with part number 8W0 698 451 AH is a mainstream brake maintenance spare part matching FAW Audi A5 and S5 Cabriolet B9/F5 chassis models, enjoying steady sales volume and recurring bulk orders in the global VAG aftermarket. It is widely stocked by professional Audi repair workshops and cross-border auto parts wholesalers, supporting one-stop combined procurement with rear brake rotors, brake wear sensors, caliper slide pin grease and complete rear brake overhaul kits. Cost-effective brake spare part for centralized bulk purchasing This 4-piece rear brake pad set fits inside rear single-piston floating brake calipers, delivering auxiliary clamping friction against rear brake discs to realize vehicle deceleration and assist electronic parking brake operation. It withstands medium-temperature friction from daily city, highway and convertible open-top driving, moderate load impact of luxury soft-top vehicle body weight and continuous chassis vibration on bumpy roads. Common aging failures of worn pads include thinned friction layers, low-speed brake squealing, uneven surface abrasion and harsh metal grinding once friction material reaches wear limit. Defective rear brake pads will trigger multiple driving anomalies: noticeably extended braking distance, sharp metal grinding noise during light braking, slight rear-end sway under medium-speed braking, irreversible scratch damage to expensive rear brake rotors and weak parking brake holding force on slopes. Most buyers combine this pad set with matched brake accessories to place consolidated bulk orders, cutting procurement and cross-border logistics costs while maintaining stable profit margins and low year-round inventory turnover pressure for distributors all year round. 100% OEM outline, friction coefficient and structural parameter matching, direct bolt-on installation without grinding or modification Produced strictly following Volkswagen Group original ETKA technical standards. The overall pad contour, mounting lug spacing, arc curvature, standard friction material thickness and caliper fitting dimensions fully match genuine 8W0698451AH. Interchange cross-reference OE codes cover 8W0698451G, 8W0698451BE, 8W0698451BJ, 8W0698451AN for compatible replacement, exclusively designed for factory standard solid rear brake discs, not compatible with carbon ceramic brake systems. No wiring adjustment or mechanical trimming is required after replacement. It perfectly fits the factory reserved caliper mounting position of FAW Audi A5/S5 Cabriolet B9 chassis and aligns with original brake disc dimensions, drastically shortening disassembly and maintenance hours for the rear brake system.
