This super - convenient tool cleverly combines four essential disc brake tools into a single, user - friendly package. It features a rotor truer, a pad spacer, a bleed block, and a piston press, making disc brake maintenance a breeze.

Using this disc brake multi - tool is easy. For the rotor truer, just place it on the rotor and adjust to get it straight. The pad spacer can be inserted between the pads to create the right gap. When it's time to bleed the brakes, use the bleed block to keep everything in place. And for the piston press, gently push it to move the piston. As for maintenance, after each use, wipe the tool clean with a dry cloth. Keep it in a dry place to prevent rust. Don't use it with excessive force as it may damage the tool.
