TOOPRE Bicycle Hydraulic Disc Brake Bleed Kit for L-TWOO R3 R5 R7 R9 Road Bike Brake Oil Filling Tool

The TOOPRE Bicycle Hydraulic Disc Brake Bleed Kit is a practical oil filling and brake bleeding tool designed for L-TWOO hydraulic road bike disc brake systems, including R3, R5, R7, R9 and related L-TWOO road hydraulic brake series.

Made from durable nylon and brass, this kit features a low-resistance syringe for smooth oil injection and a brass metal connector for better durability and longer service life. The funnel connects directly to the brake lever, while the syringe, hose, and M5 pagoda adapter connect to the brake caliper, helping air rise naturally during the oil bleeding process.

How It Works

• Brake Lever Side:
  Remove the bleed port screw with the correct Allen key and connect the funnel directly to the brake lever.

• “MINERAL OIL” means the brake uses mineral oil.
• “DOT5.1 / DOT4” means the brake requires DOT brake fluid.

Use only the correct brake fluid recommended for your brake system.
