The brake pads are braked down almost 100 percent and the slave pistons protrude far, and usually slightly asymmetrically, from the housing. In order for the new pads to fit, the pistons must be moved back to their original position. But this is not so easy, the pistons often do not want to move and only with difficulty. If you mess around with a screwdriver, you run the risk of damaging the pistons, and ceramic pistons in particular break very quickly.

What can help? Use a Q-tip soaked in dot or mineral oil to moisten the protruding side of the piston and thus reduce the static friction. And: Use a special tool to carefully push the pistons back. Speaking of special tools: Absoluteblack brings a breath of fresh air into the workshop when it comes to disc brakes. The so-called Hydraulic Brake Piston Press exerts pressure on both brake pistons and should reliably ensure that they slide gently back into the starting position. If you still haven't had enough of this clever tool, you can also use it as a bleed block when bleeding the disc brakes. Clever, isn't it?
