Proper pad bedding is essential to proper brake operation.
Initially drive the car with low braking force to check brake operation; then follow all steps listed in the
bedding process outlined at the end of this instruction manual.
During bedding do not thermally shock the rotors with aggressive braking before the rotors have come
up to temperature. Cracks on new rotors can form due to thermal shock. Gradually increase brake
pressures as instructed in the bedding procedure.
After bedding brakes re-torque wheel nuts to proper torque specifications.
If vibration occurs during normal usage, check for abnormal pad wear deposits on the rotor. Double
check all fasteners and repeat the bedding process 2-3 cycles until the pad deposits on the rotor
becomes uniform.
If the vehicle is driven in adverse weather conditions, STaSIS Engineering recommends annual
cleaning and inspection of the rotor crescents. A common source of vibration can be attributed to dirt
completely filling in the crescents on the inboard side of the rotors which in turn will not allow the pad to
function properly.
Brake rotor wall thickness wear limit is 1.0 mm per side of rotor. Rotor face runout limit +/- 0.010 in,
when taking measurement make sure rotor is tightened down to the hub at all 5 bolt locations.
