The Shimano CUES BR-U8010 is a flat mount hydraulic disc brake caliper built for road, gravel and city bikes, delivering the confident modulation and consistent control Shimano hydraulics are known for. Its flat mount body and straight hose joint keep the rear of the frame clean and compact.

Highlights

• Two-piston hydraulic caliper for strong, controlled braking
• Flat mount fitting for a tidy, integrated look
• Straight hose joint routing for a streamlined install
• Runs on Shimano mineral oil with ONE WAY BLEEDING for fast, clean bleeds
• Compatible with Shimano ICE Technologies resin pads
• Supplied with a 140/160 mm rotor mount adapter

Reliable hydraulic braking

The two-piston design balances stopping power with fine modulation, so you can scrub speed smoothly on descents, in traffic or on loose gravel. Sealed hydraulics keep performance consistent in wet and dry conditions with minimal maintenance.

Clean flat mount design

Flat mount and a straight hose joint give this caliper a compact, integrated profile suited to modern road, gravel and commuter frames. The included adapter lets you set the caliper up for either a 140 mm or 160 mm rotor.

Easy to maintain

Shimano's ONE WAY BLEEDING routes mineral oil cleanly through the system to help prevent trapped air, making bleeding quicker and tidier. Replaceable ICE Technologies resin pads keep the caliper running quietly with good wear life.

Compatibility & fit

This is the rear, flat mount version of the BR-U8010 caliper. It fits frames with flat mount rear brake tabs and accepts a 140 mm or 160 mm rotor using the supplied adapter. It uses Shimano mineral oil and L-type flat mount brake pads (L03A/L05A), and is designed to pair with Shimano CUES hydraulic disc brake levers.
