Brakes Warped Rotor 

Great animation. Explains warped rotor very clearly.

the best straight to the point

I can’t believe how many people fall for this still. If your rotor is doing that, it’s your hub or bearings. Not your rotors. A rotor does not and will not warp under the heat of braking even f you were under track conditions. The vibrations and pulsating you feel when you assume your brakes are “warped” is actually unevenly deposited brake dust material from the pads and different heat cycles. Whether you never bed them properly when you first got them, or you just put new pads on old rotors. There are a lot of ways your rotors can “warp” aka, get deposited unevenly. No brake rotor on a car is warping and running like this animation that simply does not happen unless there was a major accident or you installed them wrong. Rotors are made with high carbon alloys and do not warp. If the rotor actually was doing that with the wheels torqued properly around it, the car wouldn’t even be mildly drivable

What causes this could it be the sliding pins on the caliber

very good animation..

Straight up

Is warp came from glowing/melted rotor due high heat ? Or high heat then splash by rain instantly?

my rotor was wrapped but i don't feel it pulsating because the caliper pin was stuck.

Can low pads cause a warped rotor?
