Excessive or heavy and continuous braking may warp brake rotors. Braking hard (heating the rotors a lot) and then going through water (which quickly cools the hot rotors) may also cause the rotors to warp. If the brake pads or brake rotors are getting thin, the rotors will warp more easily.
No, it would just cause the car to handle poorly and wear tires. Rotor warping is caused by heat. If the vehicle carries heavy loads and routinely builds a lot of heat stopping it can cause the rotors to warp. Also, if a caliper does not completely release the rotors can warp. Sometimes they just warp with normal use.
Rotors normally warp due to two things. Either the wheels were install with the lug nuts torqued too much or heat has warped the rotors. The lug nuts must be torqued to exactly the factory recommended lb/ft. Too tight and the rotors will warp. Also excessive heat from riding the brake pedal or from lots of stops from high speed will warp the rotors.
Rotors warp when they overheat. Perhaps you're riding the brakes, have a sticking caliper or are going downhill a lot and are overheating the brakes that way. Often pulling a trailer will overheat the brakes, especially if the trailer does not have electric brakes. If none of the above seem to apply to your situation, perhaps someone put cheaper rotors on the vehicle; some of the import rotors look the same but they warp quite easily. Also not torquing the lug nuts correctly can warp the rotors. If the lug nuts are put on too tight the rotors will warp on some vehicles.
Warped rotors. Driving using the left foot to brake causes the rotors to heat up. Quenching the hot rotors by driving thru water will cause them to warp. The warped rotors cause the pedal to pulsate.
calipers may not be depressing all the way , causing the brakes to drag and heat up rotors causing them to warp + another possibility is tightening down the rotor TOO tight onto the hub- or - not having it turned and rubbing uneven- good idea to turn the rotors onn each brake change if you have been just leaving the rotors on- and changing pads- this may be the issue- 2dynamic
I would suspect the lug nuts were not torqued to the correct specs and that has warped the rotors. Over-tightening the lug nuts will warp the rotors. Can also be worn suspension parts.
Your rotors are warped. You will need to remove the pads and rotors and take the rotors to a machine shop and have them turned. Then install new pads. Make sure you torque the lug nuts to factory specs. Over-tightening the lug nuts can warp the rotors.
This is normally caused by warped rotors. They will have to be replaced or resurfaced if possible. When you reinstall the wheels make sure to torque the lug nuts correctly as over-tightning them will warp the rotors.
It is 80 lb/ft. Do not torque any higher or you will warp the rotors.
This is not much information, but I'll give it a try. If the front brake rotors have too much run-out, "wider in some spots than others" then the rotors need refaced or replaced. If the problem is in the rear brakes, the brake drums are out-of-round and need resurfaced. If you feel the tremble in the brake pedal when you brake, then the problem is certainly in the brake system. ------------ He is correct...the rotors are probably warped. Replace the rotors if they are warped that bad. You can get them turned but they are going to be thinner than new rotors and whatever caused them to warp last time will happen faster. (heavy braking and riding your foot on the brake can cause the rotors to warp)
What you're describing sounds like "disk brake chatter". It's a condition caused by warped rotors. Rotors often warp when they're old and/or have been overheated.
