I took my car to the mechanic. He said that my rotors weren’t warped. They just had an uneven brake pad deposited on them. And I fixed it :D.

Thanks for your help, Sean!

I’m afraid that test will not be adequate for detecting excessive runout (which is what most people mean whey they say the rotor is “warped”).

It’s also possible you have an uneven distribution of pad material on the rotors. This can happen when the brakes get hot, then you park and immediately put the parking brake on. The rotors will cool unevenly, and you may get extra pad material build up underneath the brake pads.

All this to say: don’t rule out an issue with the rotors just yet. It might be wise to have a shop check your rotors, and feel what you’re feeling under braking.

Loved all that you shared in this post!

I have a 2015 Subaru Impreza, and getting a lot of vibrations in the pedals when I brake.

I took off the wheel and put a ruler next to the rotor to see if it was warped, but I could not spot any problems.

Could my rotors still be warped enough (but not enough to be detected by the naked eye) to cause vibrations? If not the rotors, what else should I check?
