Brake rub after pads and rotor change

Hi Guys,

So I’ve changed both of my rotors ands pads. Now the rotors are touching against the brake pads everywherec not just at a specific point. So it looks like the pads are too close to the rotors. Any advice on how to widen the brake pads?

I’m using Shimano XTR M9000 brakes

Thanks

    You need to push the pistons back in when fitting new pads. With the wheel off, take the pads out and use something like a tyre lever to push both pistons in. Be gentle with the pistons as they can get damaged with metal tools.

    Perfect, thanks!

    If that doesn't work, you can release a small amount of brake fluid from the brake lever and that takes a bit of pressure out of the system.

    If any doubt go on YouTube and search parktools tutorials.

    Is it just a light rub or actually binding? Not at all unusual to get a little light rubbing (won't slow the wheel noticeably if you lift it and spin it) while the pads bed in and you risk creating a bigger issue if you fiddle unnecessarily.
