Civic brake disk thickness?
Hi, just measured the thickness of the front brake disks on my Civics,
but I could not find the minimum thickness engraved on the discks. So I wonder if any of you knows ths specs, minimum thickness, and if you also know the maximum thickness (when the discks are NEW) that would also help (i.e. I could figure out how much I used and how much I have left. Civic 2001 LX Manual: 20.80 mm (59k miles) Civic 1997 LX Manual: 20.25 mm (114k miles) Thanks. |

The service limit is 19.0 mm. Your 1997's rotors are not even at the halfway point (20.05 mm) for wear. (This assumes they are not scored badly and thickness is even.) Majestic's online parts site indicates the 2001 LX and 1997 LX use the same front rotors. For your reference, my 1991 Civic LX's front rotors at 168k miles are not at the halfway point, either, though they're getting close. I do brake a lot with the engine, as opposed to the front and rear brakes. While I'm watching thickness variation and one bad score on one of the rotors, I'm figuring my Civic's rotors are going to last the life of the car. |

When Honda front break pads wear down to a certain minimum thickness, a
pin will start touching the rotor surface when you break, and you will start to hear a high pitched scratching sound. That is when you change the pads. I think the 2001 Civic is the same way (I do not know whether this is the situation with ABS equipped cars-but the LX does not have ABS as far as I know..........). chibitul wrote: > Hi, just measured the thickness of the front brake disks on my Civics, > but I could not find the minimum thickness engraved on the discks.

The Brembo have already survived 4 pads and 190,000km. Hopefully, it won't be too much of a problem to remove 4 years of rust off the original rotors when the Brembo finally give-up.
