What is included

One Hawk Performance HB905Z.646 front-axle brake pad set. Rotors, brake fluid, wear sensors, replacement hardware, and installation labor are not represented as included.

Required and recommended supporting components

Inspect the front rotors, calipers, hydraulic components, brake fluid, pad wear sensors, and mounting hardware before installation. Replace or service any component that does not meet current Porsche and Hawk requirements. Do not install these pads on PCCB/carbon-ceramic rotors.

Installation notes

Follow current Porsche procedures and Hawk's application-specific instructions. Hawk directs installers to confirm secure pad positioning, inspect fluid and hydraulic components, evaluate rotor condition and contamination, and verify caliper movement. New pads must be bedded according to Hawk's current street-pad procedure and allowed to cool fully before normal use.

Coding and calibration

No ECU tune is required. Any brake-service mode, electronic parking-brake procedure, wear-sensor reset, or diagnostic step must be determined from the exact vehicle and axle service scope.
