## Description

The Girodisc A1-075 front brake discs, measuring 398 × 36 mm, enhance braking endurance during sustained use on Ferrari 599 GTBs equipped with carbon-ceramic rotors (2008–2012). Their cast-iron rotors and aluminum hubs form a floating assembly designed to manage thermal stresses and facilitate rotor replacement due to wear. Sold in pairs, with one left-hand rotor and one right-hand rotor.
These rotors are intended for the front axle of compatible vehicles in the configuration specified below. They retain the calipers from the compatible mounting; any required spacers and pad specifications must be observed.
The cast iron track and floating connection allow the disc to accommodate thermal expansion differences between its two parts and center itself between the brake pads. This construction also makes it easier to replace the tracks when they are worn.
The hub is made of 6061-T6 aluminum. 
New brake pads must be installed with new rotors or new track sections. Their shape and compound must match the mounting configuration, the cast iron, and the intended use; follow the specific requirements for this part number and perform the prescribed break-in procedure.
On compatible vehicles originally equipped with carbon-ceramic rotors, this pair provides a conversion solution to high-quality cast-iron rotors. It allows you to remove and store the expensive original carbon-ceramic rotors to preserve them during heavy-duty use, while reusing compatible calipers. Use new brake pads suitable for cast iron and adhere to the pad shapes and any spacers specified by the part number. Replaceable brake pads reduce the cost of replacing braking surfaces in heavy-duty applications and offer a choice of trims to tailor bite and pedal reaction to the intended use.

Brake Pads and Brake Systems for Compatible Vehicles
Select brake pads whose shape is compatible with the calipers, the track, and/or the A1-075 rotor, and whose compound is suitable for sport driving or track use. The Endless, pagid Racing, or Ferodo Racing ranges may be considered after verifying the appropriate part number.
For intensive use, we recommend compatible aviation-grade flexible hoses and high-performance brake fluid that meets the vehicle’s specifications, along with proper bleeding and fluid replacement. This recommendation complements a mounting compatible with the original hydraulic system.
Maintenance of the Girodisc mounting on compatible vehicles
Replacing the pads alone helps keep the controlled rotors in good condition. Reusing a rotor for up to three pad replacements is subject to inspection of its condition, its mounting components, and the mounting instructions; this number does not constitute a guaranteed service life. Use a new mounting component each time you replace the pads.
FAQ — Girodisc A1-075 for compatible vehicles
What are the sizes of the A1-075 discs for my vehicle? The part number shown measures 398 × 36 mm and is mounted on the front axle. The diameter alone is not sufficient: also check the brake system type and mounting requirements.
Is the product sold in pairs? Yes. It includes a left and a right disc for the same axle. Both discs come with their disc bells.
Do I need to replace the brake pads on my vehicle?Yes. Always install new brake pads with new rotors or new braking surfaces. Use a compound suitable for cast iron and your intended use. Brake pads with a maximum radial height of 66 mm are required for this braking surface. Shapes 1382/1405.
How do I identify the left and right sides? Girodisc rotors come with a label attached to each rotor: LEFT for the left side and RIGHT for the right side, as viewed from the direction of travel. On a left-hand-drive vehicle, “LEFT” corresponds to the driver’s side and “RIGHT” to the passenger side. Follow these labels and the instructions. On models with curved internal fins, the rolling direction depends on this internal ventilation; the surface grooves alone are not sufficient to determine the side.
How do I break in this mounting on my vehicle? Follow the Girodisc procedure and the brake pad manufacturer’s instructions to build up an even transfer ply. The PDF documents below detail installation and break-in.
PDF Documents for Mounting and Break-in
We have included two PDF documents below: an instruction manual for installing and breaking in the discs, and an instruction manual for installing new tracks on existing bowls. Consult the document that applies to your specific task before you begin.
