Polini For Race 4-piston radial brake caliper.

The Polini brake caliper is precision-machined from a single block of hard-anodised aerodynamic aluminium. Upgrading from 2 to 4 pistons increases friction surface by 30%, reducing temperature peaks for enhanced reliability and longer lifespan compared to standard calipers.

• Piston diameter: 24 mm (4 pistons) for increased braking force.

• Design: Optimised for stiffness and reduced volume.

• Installation: Can be mounted on both right and left sides, front or rear, by inverting the bleeding connection. Radial connection with 8 mm screw, 84 mm hole centre distance.

• Pads: Supplied with sintered pads; carbon-ceramic pads available separately.

• Compatibility: Can be installed with a dedicated Polini caliper adaptor.

• Hydraulic connection: Works with Polini pumps and reservoirs machined from hard-anodised aerodynamic aluminium; 8 mm union, adjustable lever position.

• Accessories: M8x1 connection screws available; optional adaptor for 10 mm pipes.

Features:

• Increased braking force and surface area.

• Reduced thermal stress and improved reliability.

• Versatile mounting options for front/rear and left/right sides.

• High-quality aluminium construction, lightweight and aerodynamic.
