Minimum thickness for buick lesabre front rotors

Auto Parts Stores have books for that spec

I don't know the min thickness, but I have an outback just like yours and if there is a problem with uneven rotors it's usually cheaper and easier to buy aftermarket at NAPA auto or other supplier (shop around) and trash the old rotors. If the rotors can be turned then keep them for the next brake job and use them then. Outbacks are easy to do about 30 min a side rotor and pads after the wheel is off, just did mine.

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.

rotor thickness is cast into the rotor but if you cannot find it then contact a brake shop as they have the minimum measurements for all vehicles .

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.

Its minimum thickness must be 22mm but the specified size is 25.4mm which would fit in perfectly

depends on your state/province and common sense. if you must ask this question, replace the rotors.

MINIMUM THICKNESS FOR FRONT BRAKE ROTOR IS. 0.972

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.
