Light brake caliper for hydraulic brake systems

Thanks to the brand new design, the DURA-ACE BR-R9270 hydraulic brake caliper is more compact than ever. The monobody construction ensures low weight and high rigidity and thus proves that high performance is possible even with compact dimensions.

With the brand new monobody construction, the peak of high braking performance has now been reached. The lighter BR-R9270 brake caliper offers a larger pad spacing and reduces the noise level. Finally, a new venting process also makes maintenance easier than ever before.

Highlights

  • One-piece construction for maximum rigidity and low weight
  • A 10% greater gap between the brake pads reduces the likelihood of brake discs grinding
  • Maintenance-friendly venting process
  • Compatible with various brake pads (K04Ti metal, L04C metal, K03Ti synthetic resin)
  • 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.

MONO BODY
MONO BODY brake caliper is machined from a single, cold-forged block to maximize rigidity. This one-piece MONO BODY brake caliper with its perfect balance of stiffness and weight is a component of our Linear Response hydraulic brake system. The linear response ensures high performance and excellent controllability of the performance.

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.
