Replacing Brake Levers / Brake Line to Assembly Set

Video Tutorial: Not available

Steps to Replace Brake Levers:

1. Remove the existing brake lever

   

   Remove the plastic cover over the brake line screw (pliers may help).

   • Unscrew the brake line screw and disconnect the brake lever. The lever is now free from the handlebar.

2. Prepare the new brake lever

   • Remove the brake lever plug screw to make room for the brake line screw.

   • Ensure you have the brake line plastic casing, brake olive, and brake line-to-lever screw (can reuse from old lever or purchase separately).

3. Install the new lever

   • Attach the brake line to the new lever and secure it on the handlebars.

   • Reconnect the pin connection to the main connectors.

   • Test the brake lever to ensure proper response.

   • Check that the brake sensor "!" displays correctly.

   • If brake fluid has spilled or been lost, refill/bleed as necessary (see below).

Replacing Brake Calipers / Brake Line

Video is based on Mantis Pro SE and Wolf Warrior 11, but applies to other models. Note: Calipers may differ by model.

Replacing Rotors

Video Tutorial: Rotor Replacement

• Process is the same for front/rear and for 140mm/160mm rotors.

• Requires removal of the motor/wheel:

  1. Remove motor caps to access motor nuts.

  2. Remove motor nuts and hook spacers.

  3. Free the motor axle from the swingarm/fork.

  4. Remove rotor screws (6 total) and replace rotor.

  5. Reinstall rotor and motor/wheel.

Important: Do not use WD-40 on rotors.

Refilling Brake Fluid

General Brake Troubleshooting

Common Issues & Solutions:

1. Brake levers not responding / pads not contacting rotor

   • Check brake fluid. Refill/bleed if needed.

   • Inspect brake pads for wear; replace if necessary.

2. Squeaky brakes / pads not catching rotor / rubbing noises

   • Adjust caliper screws to loosen/tighten caliper.

   • Use a brake lever or Velcro strap to engage lever while adjusting.

   • If needed, add caliper spacers (1–3 per side).

Video Tutorial for Adjustment: Brake Adjustment Guide

1. Brake lever causes lights to flicker (Wolf King / Warrior GT)

   • Usually caused by a faulty step-down converter. Replace the step-down; replacing the headlight does not fix this.

2. Brake lever disengaging

   • Scenario 1: Brake lever fault → cracking noise when pulled indicates lever replacement.

   • Scenario 2: Caliper fault → replace calipers or send scooter in for repair.

3. Skidding / burning rubber / jerky brakes at high speed

   • Check if ABS is turned off. Turn ABS on in advanced settings to smooth braking.

   • If problem persists, escalate to technical support.

4. Brakes locking up

   • Adjust PD ABS setting: switch from 1 (on) to 0 (off).

   • If issue persists, contact the technical department.

This guide covers lever, caliper, pad, rotor replacements, fluid maintenance, and troubleshooting for Kaabo scooters. Follow the videos and step-by-step instructions carefully to ensure safe and effective brake performance.
