Review the Outbraker Brake Splitter & Booster installation process

The above video demonstrates how to install the Brake Power Booster. The installation process for the Brake Splitter & Booster is conceptually the same. Check installations of the Brake Splitter & Booster on an MTB and on a road bike.

  1. Remove the brake hose from the lever using an 8mm wrench.
  2. Install the Outbraker Brake Splitter & Booster onto the desired brake lever using a 12mm wrench.
  3. Tighten the connecting bolt using an 8mm wrench while holding the brake cable into the body of the Outbraker.
  4. Bleed your brake and add oil (follow the instruction manual of the hydraulic brake brand that you are using).
  5. Adjust the desired position using the 0.9mm hex key included in the package.


How the Outbraker Brake Splitter & Booster works

The Outbraker Brake Splitter & Booster comes graduated to the minimum position of the dial (0º, that is, the oil tank open to the maximum). This means that there is the same oil capacity in the circuit as before and therefore braking is not affected.

To give more braking power and therefore more pressure to the hydraulic circuit, we must turn the dial clockwise. The system allows up to 4 turns of 360º. The best way to find the adjustment that suits you is to do it gradually.

We recommend first installing it with the dial turned to the minimum (counter-clockwise). Once installed, you can gradually increase the power. Between the initial setting point of 0º and the maximum of 1440º (360º x 4 turns) there is an infinite scale of positions in which one has to feel comfortable.

Warning: We do not recommend turning the dial to the maximum as it is too much power and could burst the internal circuit of the brake lever.
