Brembo M4 radial callipers have been a premium Brembo upgrade calliper for a long time and are still an extremely popular option. Designed to work as a direct replacement to your OE callipers, but also a great option if you can find an adapter kit. Very popular as a conversion on Harley Davidson models.

The Brembo M4.34 is a long established high performance road calliper, popular both as a replacement for compatible original equipment and as a braking upgrade for custom applications.

Its monobloc body is cast from a single piece of aluminium, providing high stiffness and precise braking response while keeping weight down. Four 34 mm aluminium pistons provide an immediate, powerful response at the brake lever and distribute braking force evenly across the pad surface.

Part of Brembo’s Prime range, the 220988530 is classified as an OE equivalent product, combining Brembo quality, safety and reliability with high performance road capability. Its 100 mm radial mounting centres make it directly interchangeable with compatible Brembo street radial callipers, while suitable adaptor kits also allow the M4 to be used in a range of custom conversions, including Harley Davidson applications.

The 220988530 features a titanium finish, four 34 mm aluminium pistons and 100 mm radial mounting centres. Brake pads are included.
