O-RING - BRAKE (Hyundai HN0634-306-017)

HN0634-306-017: A worn brake O-ring can lead to fluid leakage and reduced braking force. This aftermarket replacement part references Hyundai as the OE maker and carries the cross-reference number HN0634-306-017. The O-ring functions as a static seal within a brake assembly, preventing fluid bypass between mating surfaces. A common failure consequence is gradual loss of brake pressure, resulting in a spongy pedal feel. During a brake service, the O-ring should be inspected for cracks or flattening that compromise the seal. This item ships at approximately 0.004 pounds. Verify the serial number or application, then call (562) 693-7748.
