Would warped brake rotors cause a vibration when driving? How can you check to see if your rotors are warped? I have a 2008 rav 4.
Try driving a little, and compare the temperature of the front right and left disks. Listen/watch for the sizzle from a wet Q-tip rather than burning your fingers.I do see alot of brake dust in the front driver side brake. And i believe this is the rotor that it mostly off.
When toyota did that test they said they could touch my brakes with there finger. I know that it does heat up once in awhile. But it's very random. Could my brake pads be sticking? Would my car be safe to drive if my brake pads stick randomly or if i do have warped rotors?
Brake Caliper Sticking Causes and FixesDisk brakes don't actually "stick" since the brake pads are free floating and would be moved away from the rotors by any variations in rotor trueness.
What will usually happen if the rotors are badly warped is that the warp will tend to push the pads farther apart when you are off the brakes, as if the rotor was actually thicker than it is. This can be pretty scary in an extreme case because the next time you apply the brakes, extra pedal travel will be needed to bring the pads back into solid contact with the rotors. I had a Toyota Sienna where it got so bad it took almost a full stroke before the brakes felt like they engaged. It would take a quick second press to bring the pedal back up to normal height. Of course then there would be the violent vibration.Would it cause vibration when driving if the pads are to close to the disk and when it goes around it touches in the spots that are warped?
I get the same vibration feels but less when driving and when i press the brakes. When i lightly press the brakes it feels like they grab then don't. If that makes sense.
Its a humming noise. Like winter tires on the road but louder with some vibration. And i dont have my winter tires on yet.
