BGM four piston hydraulic brake caliper as used on the BGM hydraulic anti-dive disc brake and other aftermarket systems for both Lambretta and Vespa. Includes, two-part CNC machined housing made of high-strength anodized aluminum, brake pads, bleeder valve and crush washers.
With a 4x25mm piston, the saddle has a piston area of ​​over 40% more than a conventional two-piston saddle with a 30mm piston. The hydraulic transmission ratio is greatly improved and the braking force (at the same lever force) is increased. A further advantage of the 4 piston technology is the symmetrical load on the linings, as a result of which they always lie fully. A pad change is done quickly and easily by means of a stud screw. A great advantage in racing. Central connection of the brake line.
Fits the BGM brake caliper mount for Lambretta, PX, PK, T5 and Cosa.
