Disk rotor machining

Postby yem11n » Thu Jan 19, 2012 12:08 pm

Hi,

Can I get some input on machining the disk rotors?

Is it necessary to machine everytime the pads are replaced?
Or this should only be done if the surface of the rotors are uneven?

Also, are rotors on mxs can be machined?

cheers

MX5s can be machined, only if there is a significant lip on the disk edge, or they are not straight.

I've had a set of NA6 rotors machined after they developed a bit of a shudder. Cost was $50 for the front set from my local brake specialist. It's not necessary to machine them with each pad change. I've been getting a few pad changes without touching the rotors. If you get them machined, tou need to check their thickness with a micrometer and make sure they're not below the minimum thickness. A new set of front rotors should only cost around $100.

If your in Sydney, brookers brakes do RDA rotors for under $30 each last time i got a set.
Much better than machining.

Holy cow! That's cheap! I got my DBAs from Supercheap for $100 a set (front pair).

You can get DBA street front rotors for $60 odd from n*power and probably other places (check forum sponors?)... machining isn't much less than that. If your changing pad type it can sometimes be highly recommended to machine/replace rotors. E.g changing between a metallic, asbestos or ceramic type. EBC's pads actually come with an abrasive cleaning surface on their pads to improve bed-in.
