One-man brake bleeding is made easy by using this hand-held 34 oz (about 1 L/0.26 gal lqd) vacuum pump together with the included 24 oz (about 0.7 L/0.18 gal lqd) new fluid fill bottle. Using standard workshop air supply (6-12 bar), the kit works efficiently to flush and refill the brake system on most vehicles. The brake bleeder withdraws fluid from the bleed nipple. Hose for fluid extracting is also included. This list is for a set of brake and clutch bleeders with hose, a fluid bottle, 2 metal connectors and 4 extra connectors.
