SRAM Ultimate Piston Press A clever tool for a tricky job The SRAM Ultimate Piston Press is the perfect way to accurately reset SRAM brake pistons while bleeding, or performing regular maintenance of SRAM hydraulic brake calipers. This clever tool uses an expanding design to smoothly and evenly push pistons back into the brake caliper, without risking the misalignment or pushing the pistons too far-something that can happen with the old-school tire lever trick. The tool is able to push pistons in one at a time, and uses the caliper's brake pad retaining bolt to stay put. The top knob can be turned by hand, or by using a wrench, and the tool features a durable, long-lasting metal design.
