Pad changing warning and question


Recommended Posts

Posted

The DIY on changing brake pads recommend using a wrench to spread the brake pads and rectract the pistons. Don't do this on the the front GT3 pads. If you do you will damage the pads. The spreading force applied along the front edge of the pads will cause the rear edge of the pads to crack and flake as they are forced asymmetrically at an angle against the rotor.

Of course, if you are going to replace the pads anyway the damage doesn't matter. But if you are pulling them out to check or swap them, then be careful.

I believe some sort of impact wrench with prongs is a recommended alternative, but the only tool I have seen (see here) is probably the wrong size for the GT3 pads. Anybody have a suggestion for an alternative?

By the way, I do have one of the pad spreader tools from this website, but it works only after the pads have been removed.
