Well I know I am correct too!

I don't see the need for any further discussion.

Understand that one of these rip off artists happens to be a long time friend of mine. As an apprentice mechanic in his teens he worked for the BRM F1 team. The other has been able to diagnose and repair every fault I have either described to him or demonstrated to him by being in the car.

It is a shame more customers don't get to know their mechanics personally. Maybe their assumptions would alter.

Norri, you can't be right, because I am right!

Obviously not all techs are rip off artists, I didn't mean to come across that way, but it does exist and it does go on, you'd be foolish not to realise that, as anyone would, hence the very start of this thread.

As for getting to know their mechanics, well, I know mine very well. I always ensure I take the time and trouble to get to know anyone doing work on my car. I like to know their style, their ethics etc so I can be sure they're in line with mine and I can trust them with my vehicle

Just checked on my Audi paperwork for laughs and found as follows....
This as advised by Audi main dealer and also Indy
A quick check that I'm confident is correct means I replaced front pads at around 53k miles and then, only then did I replace pads and discs all round on the vehicle at 101,490 miles on 2nd April 2013

Pads obviously needed changed and the discs were highlighted as "approaching min thickness" levels, not at, but approaching.
Ok so I don't always hare around at 100mph anymore, or drive it like I stole it ( at least not very often ) but by the same token I don't drive like an old lady either, not often anyway

Is Audi that much better than Jaguar?
Am I just the most careful driver on the planet?
I don't think so to either of those questions
Whereas I probably spent in the region of £700 total for brake jobs, by your reasoning that amount would've been at least 3 if not 4 times that amount!

The car was and is always safe and braking in any circumstance was / is never an issue.

Who said anything about rip off artists?

F1 teams are not well known for trying to get maximum life from components.

Nobody was, I was exaggerating for effect. I intended only to convey the idea that I can trust the mechanics I am quoting.

I looked up the data points on my service history.

Rear vented discs are 20 mm thick. Discard thickness is 18 mm. After 45K kilometres (30,000 miles) the pads were under 2 mm and the discs were 18.6 mm.

If new pads were to be fitted to these discs the discs would reach discard minimum thickness after only 1/3 of the new pads were consumed. The brake job would have to be done again to replace the worn out discs. That's why you don't reuse them.

This brake wear is well documented as normal.

Front brakes are vented 32 mm and the pads last around 60,000 to 70,000 km before they wear out but the discs are always more than half worn by then. So you get twice the life out of the front brakes but the discs are still garbage on the first pad change.
