High-Performance Ceramic Brake Pads Quiet Wear-Resistant Brake Pads

***The customer placed*** an order, purchasing 3 SKUs of brake pads totaling 12,000 sets. After arrival at the ***overseas warehouse, incoming inspection found 2,280 sets judged as defective, of which 1,860 sets had chipping, cracks, and local delamination at the edges of the friction material, and another 420 sets had thickness tolerances exceeding ±0.5mm, with an overall defect rate of approximately 19%. This batch of goods affected the customer's ***after-sales project delivery. The customer demands a full batch return and replacement, otherwise they will claim compensation for line stoppage losses.

Immediately initiate 8D and CAPA, and provide a temporary containment plan within 24 hours: conduct 100% inspection of *** overseas warehouse and in-transit inventory, freeze the same batch of ***; bear the cost of third-party full inspection; for 2,280 sets of defective products, return or scrap locally as required by the customer, and issue a credit note; provide 2,480 sets free of charge as replacement, of which 600 sets by air and 1,880 sets by sea should be arranged with priority, and bear the round-trip freight. The root cause has been confirmed as unstable resin batches, temperature zone deviation in the curing oven, and insufficient moisture-proof packaging. Corrective actions include changing the resin supplier batch, optimizing the curing curve, adding thickness/shear/delamination inspection, upgrading moisture-proof packaging, strengthening batch traceability, and submitting a complete 8D report, with a commitment that the subsequent PPM for the same model will be ≤500.

***Region*** customer purchased ***batches of brake discs 9,600 pieces, brake pads 18,000 sets, suspension top mounts 7,200 pieces, ball joints 5,400 pieces, tensioners 3,000 pieces, automotive belts 6,000 pieces, packed in *** 40HQ and *** 20HQ containers and shipped to *** overseas warehouse. *** terminal repair shops reported that after installation, problems such as brake judder, brake noise, vehicle pulling to one side, and suspension top mount noise occurred, involving *** vehicles. The customer requested a full batch return and compensation of *** ten thousand USD, and required batch after-sales technical support.

Our company has launched remote technical support services, establishing a special task force jointly with quality, technical, and after-sales departments, and conducted multiple rounds of video conferences with *** customer and *** terminal repair shops. Through remote troubleshooting including batch traceability, installation photos and videos, brake disc runout, thickness, hub flange cleanliness, brake pad chamfer and shim assembly, ball joint taper hole cleanliness, top mount bearing orientation, installation torque, and road test data, it was confirmed that some issues were caused by improper installation processes, uncleaned anti-rust oil, mixed assembly of different batches, and dimensional deviations in individual batches. We remotely provided illustrated and video SOPs, trained on cleaning, measurement, installation, torque, bleeding, and break-in procedures, and guided terminal shops in conducting batch-by-batch re-inspections. For brake discs with confirmed runout (*** pieces) and brake pads with backplate dimensional deviations (*** sets), free replacements were arranged, while technical rectification and installation warranty support were provided for other qualified parts.
