## Description

The Girodisc D2-023 rear replacement braking surfaces (350 × 32 mm) allow you to replace the braking surfaces on your GIRODISC cup-style rear discs for your McLaren 540C & 570 GT (2016–2021) and McLaren MP4-12C (2011–2014), while retaining the compatible rotors after inspection. These cast iron pads maintain the floating mounting’s functionality and facilitate maintenance of a braking system subjected to repeated stress. Sold in pairs, without rotors.
The curved internal cooling fins channel air through the disc to dissipate heat during repeated braking. The floating mounting reduces stress caused by thermal expansion differences between the rotor and the caliper housing and helps center the rotor between the brake pads, maintaining consistent contact even when hot.
New brake pads must be installed with new rotors or brake discs. Their shape and compound must match the mounting, cast material, and intended use; follow the specific requirements for this part number and perform the prescribed break-in procedure.

Brake Pads and Brake System for Your McLaren 540C & 570 GT
Choose brake pads whose shape is compatible with the calipers, track, and/or D2-023 rotors, 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 Your McLaren 540C & 570 GT
When worn, replace the pads with the part number compatible with your existing rotors. 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 with each pad replacement.
FAQ — Girodisc D2-023 for McLaren 540C & 570 GT
What are the sizes of the D2-023 tracks for my McLaren 540C & 570 GT? The part number shown measures 350 × 32 mm and is mounted on the rear axle. The track height, mounting bracket, and cups must also be compatible with the mounting.
Is the product sold in pairs? Yes. It includes a left and a right component for the same axle. The brake calipers are not included.
Do I need to replace the brake pads on my McLaren 540C & 570 GT?Yes. Always install new brake pads with new rotors or new braking surfaces. Their shape and compound must be compatible with the D2-023 track and/or rotor and the calipers. Then break in the rotors and pads according to the prescribed procedures.
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 in 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 McLaren 540C & 570 GT? Follow the Girodisc procedure and the brake pad manufacturer’s instructions to build an even transfer ply. The PDF documents below detail installation and break-in.
PDF Documents for Mounting and Break-in
We’ve included two PDF documents below: one guide for installing and breaking in the rotors, and one guide for installing new tracks on existing rotors. Consult the document that applies to your specific task before you begin.
