The Shimano Professional Disc Brake Bleed Kit includes everything we need to perform professional-grade bleed maintenance so that our bike's stopping power is at its peak performance. The kit includes an M7 funnel for our mountain bikes, an M5 funnel for our road machines, a quick-stop syringe, and four different bleed blocks to suit any Shimano brake caliper so that we can do our own brake bleeds anytime we start to feel the dreaded spongy lever.
