Safety & Fitment Notes

CRITICAL SAFETY WARNING: Brake discs are safety-critical components. Never install "pattern" or unbranded cheap copies. A failure here can be catastrophic. It is strongly recommended to use OEM-spec, high-quality reproductions from established specialists or performance-graded discs. When replacing discs, you should always install a fresh set of quality brake pads at the same time to ensure even bedding and prevent warping.

Maintenance and Inspection Advice:

• Wheel Bearings: While the discs are removed, check the condition of the wheel bearings (GHK1002).
• Caliper Pistons: Inspect the pistons for pitting, which can ruin new brake pads. If there is any evidence of fluid weeping, the calipers require a rebuild or replacement.
• Performance Upgrades: For drivers looking to improve braking performance beyond the factory Girling calipers, consider upgrading to a four-piston setup.
