Yes, If you hit something. Rotors are very essential in stopping, that's what the brake pads are pressed in against to bring your car to a complete stop.
Nobody could answer that question without looking at your car. One of the possibilities is that your car is overheating. Check the coolant. By the way, if this is the case, and you are driving your car without coolant, stop driving right now because your car is in danger of being irreversabely ruined forever.
The rotors in disc brakes and the drums are what the pads and shoes rub against to stop a car. With use, the surface can get grooves in it or a build up of rust scale; reducing the braking efficiency. To machine the rotors and drums, they are put on a lathe that cuts a new smooth surface on the face of each. Depending on wear, any given rotor or drum can probably be turned 2 or 3 times before needing to be replaced.
The wheels were probably overtorqued. Have the rotors turned and the wheels torqued correctly. The mechanic more than likely overtightened the lug nuts holding your wheels on. With all of the horror stories of people having their wheels come off while riding down the road, service garages and mechanics are probably being over cautious. If tight is good, then even tighter is better. Unfortunately, what happens is that they end up warping the brake rotors (the disks that your break pads pinch together on to make your car stop). The warped rotors then give you that pulsing effect when you brake. Newer cars have lighter weight rotors that are more susceptible to warping, and, if your rotors are old or have been turned on a lathe, they are narrower and weaker and can warp easier.
Stop or slow down? It sounds like a loose/worn suspension.
bad battery or loose battery cable
You probably need new rotors
When applying the brakes; if you feel the car jumping it's usually the brake rotors need "turned". And, all depending on the age of the rotors and how much your OLD brake pads have scraped them, you might need to buy new rotors. So, my answer is TURN or REPLACE brake rotors. <end>
You may need rotors
A cars braking systemuses hydraulics to clamp rotors or expand shoe in drums to stop the vehicle. It turns the vehicles kinetic energy into heat energy through the friction on the pads and rotors/drums.
yes they need turned or replaced, 65;
check tires, driveshaft,universal joints Another answer: Do all that. The rotors were not your problem in the first place. They have to do with the brakes. They stop the car. If they were bad, they needed to be replaced. You need to be able to stop your car. You may need a complete front end job.
I would suspect warped rotors.
You have warped brake rotors. Replacement or machine work is required to stop that condition.
25 rotors. Cavaliers have 25 rotors on the car.
Although I am not terribly knowledgeable regarding car mechanics, I have done some research. A brake rotor is what actually works to stop your car when you step on the brake. This takes place when the brake pads squeeze against the rotors when braking.
They stop your car. They are round discs that are kind of attached to the wheels and the pads grip the rotors when you apply the brakes to slow down the car. When a rotor becomes warped due to excessive heat, the steering wheel will shake when you apply the brakes.
There was a lot of squeaking while braking when my car needed new rotors.
