Features & Benefits:

• The included sizes are 3/8", 7mm, 8mm, 9mm, 10mm, 11mm & 12mm. All are 6-point Hex Brake Bleeder wrenches.
• This set allows you to complete a brake bleeding service without removing the wheels and / or raising the vehicle.
• You can bleed brakes from the drivers seat without having to open and close bleeders.
• No drip design made possible by the check valve design. Tool won't bleed unless pumped.
• The one way check valve on the hose also eliminates air and old fluid from entering the brake system. Wrenches seal to the bleeder valve, and tighten or loosen the valves without breaking the seal.
