570 FE 2012 rear brake caliper question after renewing disc

The Caliper piston is probably partially or fully seized. This tool can help break it free. You may need to rebuild the Caliper. Remove the Master Cylinder Fluid reservoir cover and remove some fluid before you push the piston back into the Caliper. When doing automotive brakes, you almost always need to use this type of tool. On motorcycles and bicycles not as much.

And here is a bit more in an aftermarket kit; aftermarket kit

There you go. if it's sliding OK then you found alternative pads. people thoink all pads are the same but one set will be 6.5mm per pad, another will be 8.6mm and the third will be 10.6mm thick and simply can't be fitted.

very thin!
They have to lose heat quickly.

let us say these guys looked up the shape in a book. they find the shape and order the pads very happy - this is the mug shot of the pad. but there is usually another diagram underneath and that is the pad from the side. the profile photo. this is where they write the thickness of the pad.

If they had looked on through their book further, the diagra,m would have come up again. and maybe even again! THREE TIMES. all three look the same mug shot. but the profile will be 6.5mm, 7.8mm, 9.6mm.

If you are really stuck i suggest you remove the caliper, put the pads in and fit it all on the disc. if OK it is just the wheel's relationship to the caliper carrier and is usually the wheel spacers being wrong.

if you can't even fit it then you either have a new disc that's too thick or pads that are too thick.

I won't answer any more questions on this.
