This lock ring is a critical component of the braking system, designed to secure brake pads and ensure proper caliper function. It is manufactured to stringent Volvo standards, providing superior durability and resistance to wear compared to a compromised or broken ring. Operators may notice a rattling noise from the wheel area or a spongy brake pedal when this component begins to fail.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
An initial sign of a failing lock ring is an audible rattle or clunking noise originating from the wheel assembly, especially when applying or releasing the brakes. If left unaddressed, the noise may become more pronounced, and brake performance could degrade. Continued operation with a compromised lock ring risks uneven brake pad wear and potential caliper damage.
Ensure the caliper mounting surfaces are clean and free of debris before attempting installation. Avoid forcing the lock ring into place, as this can deform the ring or damage the caliper housing.
Inspect brake pads, caliper pins, and brake disc for wear or damage when replacing the lock ring.
