POLINI Radial Brake Caliper Kit Disc D.220 Yamaha Aerox

The POLINI radial brake caliper kit with a D.220 disc is designed to provide superior performance and optimal braking response. This kit includes an oversized brake disc, a dedicated brake bracket, and a Polini 4-piston brake caliper, ensuring exceptional stopping power. The package also includes an adapter screw for a Ø10 mm hose with seals, two screws for securing the caliper, and two spacers for the caliper (excluded in kit 178.0203).

For installation, it is essential to follow a detailed procedure that begins with thoroughly cleaning the vehicle and removing the original wheel and brake caliper. The original brake disc must be replaced with the provided Polini disc, using the original screws and applying thread locker to ensure a secure fastening. For kit 178.2003 Booster, it is recommended to leave the disc slightly loose to facilitate the mounting of the caliper.

Once the disc is installed, the wheel must be mounted with the spacers, and the caliper should be inserted, ensuring that the disc is tightened and the bracket is secured with the original screws. The caliper must be connected to the brake hose using the provided adapter and, if necessary, replaced with a compatible aftermarket hose.

Finally, it is important to fill the system with Dot 4 oil, perform bleeding, and ensure that all parts are degreased before use. After a final test, it is advisable to recheck the tightening of all screws to ensure maximum safety and performance. This kit represents an ideal upgrade for those looking to improve the braking performance of their motorcycle.
