We know we know. We're behind on our bicycle maintenance. But we're poised to get right back on track now that we have the Park Tool Hydraulic Bleed Kit. We're liking it because it's easy to use at home but it's tough enough to withstand everyday commercial use too. Two options are available. The BKM-1 will bleed most models of mineral oi1l-based hydraulic brakes whereas the BKD-1 handles most DOT fluid-based brakes. Either way you'll be able to get out any air bubbles and inject new clean fluid to keep your bike stopping on a dime. This shop-grade kit is all housed in a rugged reusable case to minimize the risk of losing any crucial equipment.
