Yup. Learning to bleed them myself would be an option but I’m a wee bit surprised that each pad change requires a rebleed.
The clamps didn’t come with the bike so the credit card will get used.
Re pushing in the pistons. Yup, did that with the worn out pads before replacing them.
On the plus side, the rotors didn’t warp like my Ice Tech rotors. 4 days of riding in the Alps proved too much for the rear one necessitating me bending it back. The front one was a real doozy. A below zero ride up Beinn Dearg saw the front one rub against the caliper by the bottom of the descent as it was a good 3 or 4 mm out of alignment. I hadn’t hit anything with the 203mm rotors as it wasn’t that type of descent. Hey ho!
