Astro Pneumatic 78613 One-Person Brake Bleeding Wrench Kit

Ideal for brake bleeding without removing the wheels and/or raising the vehicle
Speed bleed brakes from the driver’s seat without monitoring the bleeders
No drip design made possible by the check valve design. Tool won’t bleed unless pumped
The one way check valve also eliminates air and old fluid from entering the brake system
The 3 different wrench sizes (8mm, 10mm, and 11mm) seal to the bleeder valve, and tighten or loosen the valves without breaking the seal
