Auto Parts Stores have books for that spec

IT IS INBOSSED ON ROTOR IF YOU LOOK FOR IT

Call any auto parts store and they can look it up and tell you

Brake Disc (Rotor) REMOVAL & INSTALLATION

1. Raise and safely support the front of the truck with jackstands. Remove the front wheel.
2. Remove the caliper assembly and support it to the frame with a piece of wire without disconnecting the brake fluid hose.
3. Remove the hub and rotor assembly.
4. Install the rotor in the reverse order of removal, and adjust the wheel bearing as outlined in Section 1.

INSPECTION If the rotor is deeply scarred or has shallow cracks, it may be refinished on a disc brake rotor lathe. Also, if the lateral run-out exceeds 0.010 in. (0.25mm) within a 6 in. (152mm) radius when measured with a dial indicator, with the stylus 1 in. (25mm) in from the edge of the rotor, the rotor should be refinished or replaced. A maximum of 0.020 in. (0.5mm) of material may be removed equally from each friction surface of the rotor. If the damage cannot be corrected when the rotor has been machined to the minimum thickness shown on the rotor, it should be replaced. The finished braking surfaces of the rotor must be parallel within 0.007 in. (0.178mm) and lateral run-out must not be more than 0.003 in. (0.076mm) on the inboard surface in a 5 in. (127mm) radius.

Most common cause for this is rotors that have become warped. It is not uncommon if you drive fast and brake hard OR live in hilly country or with heavy loads. The brakes get hot - the more they are used the hotter they may get. When they cool they do not cool evenly. If there is enough of the rotor left it may be resurfaced to true it. However - the thinner it gets the less heat it can handle. When rotors reach a minimum thickness (stamped on the rotor) they must be replaced.

Minimum thickness is 27.9mm or 1.09"...... I dont know what "run off limit" means? It doesnt matter, the minimum is the minimum, period.

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

if you have to ask that question you should replace them
