Who's Responsible?

[Burnerman]

I agree, it can be a difficult decision for us.
I usually ask to see the car again in 6000, and the chances are things will hardly have changed.
I have to say, its usually disc replacement time too - its rare I replace pads alone unless the car is a real high miler.

If the friction material is less than the backing for the pads (about 3mm) we recommend changing them and its down to the owner to to say yes or no.

3mm can be down to metal in 3 months or less depending on how heavy the car is and driving style.

My son does a set of pads every 15k due to his driving style whereas I can do 30-35k lol

How much meat is on a new pad?, I bet 4mm is 50% worn

A new pad will have about 12/13mm of lining. Therefore 4mm is 30% of lining remaining.
I've got a set of pads here, they've got squealers on them. Using a Vernier, I've just measured the distance between the squealer and backplate. Therefore the audible warning will start when there is 4mm of lining remaining.

Often components fail because, they have been designed to fail.

Quality control is normally done by a third party, i.e. not done in house. You wouldn't want the manufacturer, or the designer, doing the quality control, would you?

Since when ? Please give examples.

I spent my whole professional life in the components industry ( pistons and rings, rubber-mouldings, magnets, speakers and harnesses ) supplying European o.e. manufacturers and never encountered this one single time. That apart, all advanced industry ( TS 16949 ) and manufacturers' own supplier quality standards require that supplier in-house QA methods are specified and results are verifiable ( records kept for x years ).

Third-party verification would never be permitted as:

a) It admits that the supplier is not competent to check its own quality and cannot therefore be viewed as an acceptable supplier.
b) This is an obvious added cost to the product which should be unnecessary and therefore is unacceptable.

You are saying this happens , which must pre-suppose knowledge, so I am asking you to share that knowledge with us to back up your claim.

I'm not going to spend time explaining to the flat earth society. There's 700,000,000 Google results there. I'm sure one of them will make it quite clear.

Well, I think that makes it abundantly clear what value you should put in the following claim by Stivino.


"Quality control is normally done by a third party, i.e. not done in house. You wouldn't want the manufacturer, or the designer, doing the quality control, would you? "

I'm surprised. What I have read over the years wouldn't have led me to expect this kind of childish nonsensical response.

Piaggio group do in-house quality control.

Usually if a part is fitted there is some kind of fall back if something goes wrong. However, brake pads are a consumable item, so good luck in trying to sort it out

I'm with Mointainwalker on this. 30 years in the car industry and I've never seen in-house QC checks subbed-out. I've seen the auditing of those checks subbed-out, but never the checks themselves. Never mind TS16949, a company wouldn't even be able to get ISO 9001 without doing in-house QC checks!
