2000 Plymouth Neon Brake Specs

The 2000 Plymouth Neon has disc brakes on the front and disc or drum brakes on the rear. The disc brakes have two important measurements: minimal rotor machining and nominal rotor thickness. The rear drums have two measurements, as well: drum discard and nominal drum diameter.

Front Rotor

All 2000 Plymouth Neons have front disc brakes. The minimal rotor machining specification is the thinnest the rotors may be and still be eligible for machining or resurfacing; this measurement is .803 inches. The nominal thickness -- the thickness of the rotor new -- is .861 to .871 inches.

Rear Rotor

Rear rotors on a 2000 Plymouth Neon have minimal machining thickness of .285 inches. The nominal thickness rating for the rear rotors is set at .344 to .364 inches.

Rear Drum

Some 2000 Plymouth Neons are equipped with rear drum brakes, which have different, but similar, ratings. The drums are measured in overall inside diameter as opposed to total thickness. The drum's discard diameter, the largest diameter the drum can be before it must be replaced, is 7.921 inches. The nominal diameter, or new diameter, of the rear drum is 7.875 inches.
