Product Features: This brake bleeder kit is suitable for bleeding brake and clutch systems for vehicles with an ABS system. The bleeder uses standard workshop air supply (10 – 40 psi) to efficiently flush and refill the brake system on most vehicles. The low pressure tank can be pre-charged with compressed air, making the unit fully portable. This brake bleeder kit is a great time saver, especially if you service brakes on a regular basis. .
