Brembo Radial GP4-MS CNC Monoblock Brake Caliper Kit 108mm 220D60030

Machined from solid aluminium billet and finished with a nickel coating that actively manages heat, the Brembo GP4-MS Monoblock Brake Caliper Kit represents the marque's racing heritage translated directly into a package that works equally hard on a demanding road ride or a track day. The 108 mm radial mounting pitch and four-piston monoblock architecture deliver the kind of progressive, fade-resistant feel that serious supersport riders demand from their front end.

Key Features

• CNC-machined monoblock aluminium body — a single billet construction eliminates flex and provides the structural rigidity that radial calipers are chosen for on the track.
• Nickel finish for enhanced heat dissipation — the surface treatment actively draws thermal energy away from the pads and fluid, preserving consistent bite across long, hard sessions.
• Four 30 mm pistons with dual seals — equal-diameter pistons generate even pad contact across the full friction surface, while the dual seals are optimised for sustained road use.
• 108 mm radial mounting pattern — matches the OE spacing on a wide range of supersport platforms without adaptation brackets.
• Compatible with DOT 4 and DOT 5.1 brake fluid — no system modification required.
• Supplied complete with Brembo High Performance Sintered brake pads 07BB3793 Sinter TT — ready to bolt on and ride.

Construction and Material Quality

The GP4-MS sits at the top of Brembo Racing's road-legal lineup because its monoblock body is carved from a single aluminium billet rather than assembled from two halves. That means zero parting-line flex under the extreme hydraulic pressures generated by a high-grip tyre on a hot lap. The nickel finish is not merely cosmetic: it raises the caliper's ability to shed radiant heat, protecting the brake fluid and extending pad life during repeated heavy-braking zones. Each caliper weighs approximately 670 g without pads — genuinely competitive against titanium-hardware alternatives at a fraction of the price.

Road and Track Performance

With a 30 mm offset, the GP4-MS positions the brake disc centrally within the pad window, which is critical for consistent wear and predictable modulation. The caliper accepts discs up to 6 mm thick, with the optimal performance window at 5.5 mm, and the friction ring specification is approximately 35 mm — compatible with many OE and aftermarket discs already fitted to the bikes listed below. Road use type-approval (ABE) is in preparation; the caliper is fully engineered for both environments.
