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

 

Oh i see, many thanks... also, wondeering about whats rule of lowest mm that will fails? below .250 or what?

thanks

 

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.
