60,000km service on my Tig....... well well.....

[Umai Naa!!]

What's with Tiguans an rotor replacement, or any new car for that matter, what happened to machining discs, can't think of any car that I've had that needed the disc rotors thrown out and replaced with a new set before being machined, new pads yes but not new rotors, are the vw disc so thin to begin with?

Having said that my independent VW/Audi mechanic told me at the last yearly service I would need new discs soon,WTF, I courteously declined and said I would get back to him when needed, plenty of meat left in the discs, just had last yearly service last month to break down the costs of pending 60,000 service probably due in a couple of months again rotor replacement mentioned(actually I brought it up) but still a fair bit of meat left in the rotor, am I missing something or are modern car rotors junk to begin with?

The rotors are too soft to machine. By the time you machine them down to an even surface, they'll most likely be close to undersized.

In a nutshell, they're designed to wear with the pads, and being soft, provide optimal breaking performance.

Hard pads and soft discs as opposed to the opposite on cars from 20 years ago.

That's the price you pay for better brake performance.

three replies all concise, thanks that answers that, having said that my DBA5000 disc rotors on my wrx did take machining twice using a race style pad(4 spot calipers) and did offer optimal braking, they're due for replacement any time but still brake well with a lip and with multiple grooves reminiscent of clay on a potters wheel, I don't know to me throwing out your discs and pads just seems redundant in thinking.
