Will the Brembo M4 fit my bike?

It fits forks with radial mounts at 100mm or 108mm spacing. Measure your fork mounts and check your master cylinder size before ordering.

Does it come with brake pads?

No. It takes the same pads as the Ducati 1098/1198, so you choose and buy pads separately.

What master cylinder does it need?

Brembo specifies a 19x18 or 19x20 radial master cylinder. A mismatched master cylinder can make the lever feel soft or overly firm.

Is it better than the stock caliper?

The monobloc body flexes less than most stock two-piece calipers, giving firmer lever feel. The gain depends on your pads, master cylinder and lines.

What brake fluid and discs does it use?

Use DOT4 fluid and discs 4.5–5.5mm thick. The friction area is 21cm².

How much does the caliper weigh?

About 1.015kg per caliper. That is heavier than Brembo's forged and billet monoblocs.

Our take on the Brembo M4 100mm or 108mm Cast Monobloc Aluminum Calipers

The Brembo M4 is a cast aluminum monobloc radial caliper sold as a bolt-on upgrade for many European sportbikes. It uses the same pads as the Ducati 1098/1198, so pad choice is wide and cheap. The monobloc body is stiffer than a two-piece caliper, which sharpens lever feel and reduces flex under hard braking. It suits track riders and fast street riders on 100mm or 108mm radial mounts; riders on axial mounts or narrow master cylinders need to check fitment first.
