Bleeding hydraulic disc brakes requires precision because the oil level directly affects brake feel and performance. The Campagnolo UT-DB011 Oil Level Tool removes the guesswork when you're servicing Campagnolo's 11-speed, 12-speed, or 13-speed road hydraulic disc brake systems. The tool fits into the brake caliper in place of the pads during installation or bleeding, ensuring you add the correct amount of mineral oil without overfilling or underfilling the system.

The aluminum tool is machined with a 1.85mm rotor slot that mimics the spacing between brake pads during normal operation. Once installed in the caliper, the tool creates a fixed reference point with no moving parts, which means you can't accidentally compress pistons or get mineral oil on your brake pads. The locking pin holes match Campagnolo caliper geometry, holding the tool securely during the bleeding process. You finish the bleed, remove the tool, install fresh pads, and you're done with the proper oil volume already established.

Campagnolo designed this tool to replace the earlier DB-010 version with refined measurements specific to their current hydraulic system specifications. The blue anodizing makes the tool easy to spot in your toolbox, and the machined aluminum construction stands up to repeated use without warping or wearing. The tool works with all Campagnolo road hydraulic disc brake calipers that use LB-300 mineral oil, covering the full range of Super Record, Record, and Chorus groupsets across three generations of speed counts....
