Our take on the Brock's Performance Brembo M4 Front Caliper Set (108mm Radial) Black

A pair of Brembo M4 monoblock radial front calipers with a 108mm bolt spacing, four 34mm aluminum pistons each, and HH-rated sintered pads in the box. The monoblock body is cast and machined as one piece, which Brembo says gives high stiffness and precise operation at low weight. They suit sport and track riders upgrading from axial or two-piece calipers, or replacing a stock radial setup. Against cheaper cast two-piece calipers they offer more rigidity; against premium billet calipers they give up some stiffness and finish but cost less and use common HH pads.

About the Brock's Performance Brembo M4 Front Caliper Set (108mm Radial) Black

This is a pair of Brembo M4 front brake calipers with a 108mm radial bolt-center. Each caliper is a monoblock, machined from a single piece of cast aluminum. This gives a solid, lightweight body with high stiffness. The design uses technology from MotoGP.

Each caliper body houses four 34mm aluminum pistons. A triple bridge shape adds stiffness. The Brembo logo is embossed and hand painted in Brembo Red.

The kit includes HH-rated sintered brake pads. It also contains an instruction manual, a set of Brembo stickers, and heat adhesives used in racing to monitor caliper operating temperature.

Questions and answers

Will these fit my fork?
They need 108mm radial bolt spacing, 22.5mm offset and 32–34mm disc height. Check your fork mounts and rotor before buying.
Are pads included?
Yes. Each caliper comes with HH-rated sintered pads. Replacements are widely available.
Are these a pair or one caliper?
It is a two-caliper kit, so both front calipers are included.
What fluid do they use?
DOT 4 brake fluid.
How do they compare with two-piece calipers?
The one-piece monoblock body is stiffer than a bolted two-piece caliper, which usually means firmer lever feel and less flex under hard braking.
Do I need a new master cylinder?
Not necessarily, but four 34mm pistons move more fluid than many stock setups. Match the master cylinder to the caliper for the best lever feel.
