A brake
caliper has zero to do with a rotor warping. Heat is the issue. Friction=heat. If you are continually warping stock brake rotors, you need an upgrade. The upgrade would be an EBR race rotor and solid mounting hardware,
a ZTL-2 caliper, a 19mm radial master cylinder, and (IMO) EBC HH pads for the street. Heck, get a TPEHAK brake scoop if you want:angel:
Possibly his Royal Highness Valentino Rossi could tell the difference in weight between the 2 calipers, but any of us mere mortals could never tell. Ever. 'Why is my bike handling differently? Oh ya, I put my wallet in my pocket':upset: Haha.
Assuming the rotor is warped is a common mistake. What is is actually doing is sticking-sliding-sticking-sliding to the pads and you need to find out why. Stuck mounting hardware or uneven pad deposits will feel exactly the same. Replacing the rotor usually solves all 3 issues, reinforcing the original incorrect assumption. But you'll want to know if you have an actual overheating/ warping issue that needs to be solved.
Remove and properly clean the rotor (clean wire, not grit) and all the hardware, lubricate the hardware with anti-seize. Then
properly re-bed the brakes. While the rotor is off, check it for flatness on glass or I use a cheap wheel balance stand to check run-out.
