A Brembo GT big brake system built for the Ferrari F40 (Excluding LM), 1987 to 1991, rear axle. The discs are 355x32mm 2-piece.
GT|A calipers are the two piece design derived from Brembo’s original equipment applications. They are the most straightforward of the GT calipers to install and suit road cars that see occasional track use.
Four piston caliper, used on front and rear axles depending on the application.
Disc face: available cross-drilled or Type 3 slotted. Type 3 slots are the pattern Brembo uses in professional motorsport. They give a strong initial bite and keep the pad face clean as it beds in.
Fitment notes from Brembo: The crossection and A, B, C dimensions reflect the dimensions of the 4-piston caliper and not the hand-brake caliper. The maximum radial dimension occurs at the relocated hand-brake caliper, so this must be factored in when choosing a wheel to fit the complete system.
What is in the kit: 4 piston aluminium calipers, 355mm 2-piece discs with bells, Brembo pads, caliper mounting brackets, braided brake lines and the fitting hardware. Contents vary slightly by application, so check the part number against the list below.
Part numbers
| Disc face | Base part | Full part number by finish |
|---|---|---|
| Cross-drilled | 2B18002A | – |
| Slotted Type 3 | 2B38002A | – |
The last character sets the caliper finish or the line. 1 is black, 2 red, 3 silver, 4 gold, 5 yellow, 6 white, 7 fluorescent yellow. S is a GT-S caliper and R is a GT-R caliper.
Wheel clearance is the thing to check first. A 355mm disc with this caliper needs a specific wheel offset and spoke shape, and the requirement for a GT-R caliper is different from the GT version. Send us your wheel size, offset and make and we will read the clearance drawing against it before anything is ordered.

Brake work is safety critical. Brembo asks that these systems are installed by a qualified technician, and the kit must be checked, bled and road tested to the instructions supplied with it before the car is driven.
