Many Toyota Alphard / Vellfire owners have asked us the same question:

“Why does my brake make a kok kok sound at low speed?”

The truth is simple —
The original factory caliper design does not include any damping ring.
Over time, the caliper pin develops extra clearance, especially after long use.

When this happens, you may hear:

• Light metallic knocking at low speed

• Small “kok kok” sound when braking

• Noise over uneven roads

This is very common, and it doesn’t mean the brake system has failed —
it’s just clearance movement inside the factory caliper structure.

✅ Our Upgraded Solution: Caliper Pin + Damping Ring

At MD AUTO TOYOTA | LEXUS Specialist, we use an upgraded caliper pin set with an additional damping ring that helps to:

✔ Reduce clearance
✔ Stabilize caliper movement
✔ Make braking smoother & quieter
✔ Improve long-term durability

The best part?
You only pay once for the upgraded pin set.
In the future, only the damping ring needs replacement — saving long-term maintenance cost.

🚗 If your Alphard / Vellfire also has this “kok kok” noise…

Send us a message with the word “Brake Noise” and we can help you check whether it’s caused by the caliper pin clearance.
