Disclaimer: The VTT HD kits are designed for street use and drag racing. Always drive within your limits. Proper bedding of the pads is crucial to achieve full braking performance. Failure to bed the pads correctly may result in only 30-50% of the braking capability. If pads glaze, rotors must be sanded down and rebedded for optimal performance.
