Hi! It's interesting that you say that discs are normally replaced after two sets of pads. My previous car, mercedes C270, had to have new pads and discs at 40K because the stealer said you should not put new pads on old discs.

That Merc dealer has two eyes on profit and none on customer VFM. Too many like that! |

From my point of view it would be great to sell a set of discs with every set of pads but they are just not needed like that, if there is a good reason to replace them (as my first statement) then get on with it, if not.....

I remember the days when people had old discs skimmed and threw them back on. |

Mustilmat - the "disc thickness" is the measured width across the friction surfaces measured by use of a micrometer or calipers. Measure across the shiny friction surfaces, NOT the rusty edge. 26mm minimum for front disc, 10mm minimum for rear disc. (I assume you have a TD4, not an i6).

Yes. Once they get below their minimum thickness they will be unable to efficiently dissipate heat which could lead to brake fade, boiling of the brake fluid, warping, heat cracks etc. Past: FL2 TD4 HSE Auto Evoque SD4 Dynamic Lux Auto Present: Audi A3 S Line. |
