You can only have them turned a few times until they are too thin to be considered safe. Usually this thickness is stamped on the rotor.
Can I reuse a resurfaced brake rotor with a new rotor on a car
The rotor will have to be removed from the car. It can be resurfaced by mounting it on a special machine that slowly removes metal from the rotor until the rotor is smooth.
If you feel pulsating, shudder, or vibrating, when you come to a stop, your rotors are warped. Remove the rotor and take it to a machine shop and see if it can be turned and resurfaced. Usually this can be done one time unless the rotor is badly damaged. The machine shop will determine if it can be resurfaced. If not, you will need to purchase a new rotor. Make sure to replace the brake pads even if they look good when replacing or resurfacing the rotor.
No you do not have to get new rotors just have them resurfaced. If they are to much warpage then you may need new ones. I would try getting them resurfaced before you replace them.
If it only occurs during braking, then you have a rotor or drum issue. Most times it is a warped or scarred surface on the rotor or drum. You may be able to get it resurfaced for a fraction of the cost of replacement.
When having the rotors on your car replaced, ask for a higher quality metal type of rotor. Inferior types can squeak and not dissipate heat well, causing problems sooner than you'd expect them to. A rotor must be replaced, instead of resurfaced, once the thickness specifications for the automobile and rotor brand are not being met. In Addition, if a rotor is cracked, warped, already resurfaced, or otherwise damaged it must be replaced. Many times drums, pads, and other automobile parts will have to be replaced if the mechanic sees problems once the old rotor is removed. A rotor replacement should not take more than one day and should not cost more than $100 for parts and labor at home, or over $400 at a repair shop.
i have 2006 endeavor changing brakes do i have to remove the two screws in the rotor to remove so i can have resurfaced
You can have your brake rotors resurface for approximately $20. The brake rotor thickness must meet minimum standards, in order for them to be resurfaced.
The minimum thickness is stamped on the inside of the rotor. If they have been resurfaced once and need it again you should replace the rotors. .905 (In thousandths of an inch) Application: Front rotor .394 (In thousandths of an inch) Application: Rear rotor With 4 cylinder engine .354 (In thousandths of an inch) Application: Rear rotor With 6 cylinder engine
You have a warped brake rotor. They can be resurfaced but the cost to replace it with a new one or resurfacing is about the same, go for the new one.
Did you have the rotors turned or replaced? If the rotor surface was not resurfaced it can often cause noise, premature wear and uneven stopping.
