If your brakes are underperforming and the pads still have life left, it's probably time to bleed the system. This tool mounts to your master cylinder and pressure-feeds fluid through the lines, making it much easier to clear air than a standard two-person bleed. Fill the top with fluid, twist the knob to let fluid flow into the system, pump the brakes, close the knob, and repeat until the pedal feels right — if there's still air in the lines, you may need to drain some fluid from the caliper and start again. Comes with M10, G1/8, and M6 adapters to fit most chassis and brake systems. Bleeding your brakes regularly, not just when something feels off, is good practice for keeping them at their best.
