The BR-RS505 brake caliper by Shimano - slim, sporty design
Shimano BR-RS505 is a flat mount brake caliper at the 105 level with 2 ceramic pistons. In addition to aerodynamic advantages, it offers a slim, sporty design that integrates harmoniously with the other Road bike components. Ice-Tech cooling technology, in combination with the appropriate rotors and pads, ensures consistent braking performance in all weather conditions and on steep descents. BR-RS505 also convinces with its simple One Way Bleeding method. A synthetic resin pad with cooling fins and an adapter for mounting a 140 or 160 mm brake rotor on the front wheel (for the front version) are included.

One-Way-Bleeding was developed for quick and easy prevention of air in Shimano's hydraulic system. They have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system.
One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
Brake fading during prolonged uninterrupted operation, e.g. downhill, impairs braking performance. Shimano has introduced brake discs and pads with Ice-Tech technology to create a cooling technology for consistently high braking performance. The brake rotor has a three-layer stainless steel sandwich structure on the outside around an aluminium core. It radiates heat better and reduces a surface temperature from 400° C to 300° C, for example. The brake pads also have optional cooling fins. The design of the rotor in combination with the cooling fins results in a longer service life of the pads, less braking noise, less fading and a lower weight.
