A full replacement for the hydraulic end of a Dominion lever – master cylinder and lever blade in one assembly, for a lever that's been crashed or is leaking at the reservoir.

Highlights

  • Tool-free reach adjustment
  • Flip-flop lever orientation (runs on left or right side of the bar)
  • Sealed cartridge bearing lever pivot
  • Fits Dominion A2 and A4

Compatibility & fit

Fits the Hayes Dominion A2 and A4 platform. Contains the master cylinder, so it's covered by Hayes' lifetime leakproof warranty on top of the standard two years. Bleeding is needed after fitting – a job for the Tune workshop.

Hayes Bicycle Group's two-year warranty covers defects in materials and workmanship, and Hayes' limited lifetime leakproof warranty covers fluid leaks from the master cylinder and caliper after the first two years. Normal wear and tear, crash damage and labour aren't included. For warranty support, return the product to Tune Cycles and we'll manage the claim with Hayes' Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
