Shimano Ultegra BR-R8170 brake caliper front wheel

Extremely maintenance-friendly brake caliper for hydraulic brake systems

To the great delight of drivers and mechanics, the new ULTEGRA BR-R8170 brake caliper offers improved controllability, a quieter braking system and an extremely simple bleeding process.

The ULTEGRA R8170 disc brake caliper offers racing cyclists a completely new feeling of control thanks to its improved controllability and faster initial braking force. Despite the flatter design, the system causes less brake noise than ever before and is easier to maintain.

Highlights

• A 10% greater gap between the brake pads reduces the likelihood of brake discs grinding
• Maintenance-friendly venting process
• Compatible with various brake pads (L03A resin, L04C metal)
• Recommended brake line SM-BH90-JK-SSR optionally available

Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

ICE Technologies
Fading, which can occur in the brake disc and pad when braking continuously on long descents, impairs braking performance. Shimano introduced ICE TECHNOLOGIES brake discs and ICE TECHNOLOGIES brake pads to create a cooling technology for consistently high braking performance. The brake disc with its 3-layer sandwich structure made of stainless steel, aluminum and stainless steel offers better heat dissipation. The brake pads also have cooling fins. The construction of the disc in connection with the cooling fins results in a longer service life of the lining, less braking noise, less fading and lower weight.

ONE WAY BLEEDING
ONE WAY BLEEDING was developed to be able to quickly and easily prevent air from being in the hydraulic system. Shimano has optimized the routing of the brake fluid throughout the system in order to prevent air bubbles from getting stuck in the system. The pipe path of the mineral oil in only one direction, together with the funnel for filling, enables clean, problem-free venting.
