What is minimum rotor thickness for 2007 elantra

Each brake rotor has the minimum thickness marked on the rotor. Keep in mind also that the comparative thickness of each side of a vented rotor must be considered. Even if the overall thickness is greater than the minimum, each side must be within .040" (1mm) of the other.

Hello Bethany,
I know a bit about cars but being English I don't understand about rear rotors. I am guessing it is what we call brake discs or disc brakes.
Unlikely I would have thought the actual rotors or discs would be worn to a thickness of 6mm (which would be bad news) and perhaps you are referring to the thickness of the friction material?

It is only a relatively small percentage of braking effort that is exerted by the rear brakes so the rate of wear is much lower than the front brakes so it isn't unusual to discover new friction material isn't much thicker than about 8mm, though many are thicker and some are as thick as those at the front.

It is a general rule that is adopted by most brake and car manufacturer that replacement of friction material or disc pads is not required until there is only 3mm left and I have seen manufacturer's recommendations saying 2mm.
With 6mm of friction material still remaining which is two or three times the recommended minimum there would be no grounds to refuse certification.

Take your car to the service shop and the guy in the greasy overalls will ask himself if 6mm will last you until your next visit and if he is honest he will replace only after asking you what sort of mileage you cover. If he is normal he will grab the extra profit with both hands...

For a 2000 Buick LeSabre

FRONT BRAKE ROTORS:
Discard Thickness30.7 mm (1.209 in.)
Lateral Runout (New)0.06 mm (0.002 in.)
Minimum Thickness after Refinish31.08 mm (1.224 in.)
Rotor Diameter 15 inch Wheels (New)278.0 mm (10.9 in.)
Rotor Diameter 16 inch Wheels (New)303.0 mm (11.9 in.)
Rotor Thickness (New)32.20 mm (1.267 in.)
Thickness Variation (New)0.025 mm (0.001 in.)

ON most disc rotors the minimum thickness is cast into the body of the rotor and will read min thickness and a dimension. The dimension is also available in the workshop manuals and from the service department of your vehicle. Do not be surprised if you find that your dimensions are almost at do not machine limits as original rotors are not much thicker than the low limit.

THE REAR BRAKES ARE 8.4mm(1.024")!!! DO NOT TURN YOUR FRONT ROTORS TO THIS!!! The front are a minimum of 26mm (1.024")

All are different, on the back side of the brake rotor , will have a stamp with (MIN) and some number after it the will be the minimum spec thickness for the brake rotor.

there is many kind of brake system of ur truck here i will send u everything about the brake and i hope its help

* All brake rotors have a discard dimension cast into them. Replace any rotor that does not meet this Specification. After refinishing the rotor, replace any rotor that does not meet the minimum or discard thickness specifications.
