Md state inspection FAILED my audi a4 1.8t rotor size.. need help
 

Hi there,

I just bought a new 99 audi A4 1.8 quattro

Took it to md state inspection and found that they said my rear rotor - .279 and .290

Which, they said they should be .314...

Should i listen to them and change new rotors or are .279 and .290 normal and still alive for other miles?

or Should i try other different md state inspection location?

Need your opinions...

thanks

total crap I would think ( do they work or not ) do the breaks work?

Yes, the brakes work GREAT! no shaking or anything... i was like huh about must getting new rear rotors...

it could be the rotors are too thin due to wear ( not unreasonable );)

Yeah? but do you know what size that shld pass? or fail? like .279 nd .290 is too thin?

below 279mm is micro and if they work well its not a fail but if they are burned out then change them and the pads

as a mechanic I have a cheat, the tester feels the edge of the rotor and if its high that signals break wear so if you grind that edge off the results are amazing;)

Oh, how ironically that they passed my brake pads but rotors naw... So, all i have to is get new rear rotors?

The minimum rotor thickness is cast onto the disc.
