*Please note: LH4 Service Kits are designed for brakes with the following serial numbers: X, a, a1, or a1(1)
You can find the serial number laser etched on the lever bracket, where the clamp is mounted to the handlebar.
If your brakes do not have a serial number, then you will need the Previous Generation service kit.
