Default on average how long do your front disks last.

I ask this question as I recently had my car serviced at 20,000 miles, the OPC advised that my front disks and pads would need replacing within the next 4k.

The pads I can understand but new disks at 24k seems a bit drastic?

I don't track the car its all motorway urban and the odd blast over the moors...

Interested in your thoughts and experiences.....

Thanks

Except for the rotors on a Jetta that rusted away with 9,000 miles , I've never replaced rotors on any car in 40 years of ownership
Most cars were sold/traded with 40-50 K miles
'99 996 Porsche 44 K...sold with the .same rotors and pads the car came with.
Something seems odd.

20K is barely broken in - seems very odd - even for pads.

My PCCB rotors and pads were replaced by the dealer before I took delivery. Car has 24K on the clock. Thank God they did it and not me!!!

It does seem odd hence the post, they provided me with the following measurements

front pads at 6mm, min 2mm, recommended change at 4mm
front disks at 32.58mm with .58mm usable. (34mm when new)

Pads show as amber but disks as green (they use a traffic light system) on the service report.

It was the service guy who said they will need changing at 25k? if I work out the wear rate per thousand miles its .071mm so they would be down to 32mm in 28,000 miles still seems pretty poor....

I would seek a different opinion. Not rotors and not even pads on a street-driven car. I can see pads at 50-60k miles depending on driving conditions.

Seeing that (if the measurements are correct) you are fine. You should change pads when the car tells you to do so (brake pad light on).

Brake wear results from how you drive the car, not mileage.

I would expect my brake wear to be quite low because here in Texas the roads are long, wide and with low traffic. If I was back in Blighty, then I would expect my brake wear to be much worse because the traffic is bad and there is a lot more braking done for a given distance.

True, but not 20k miles on this car.

I sold my 996 with 61k miles on the clock and on original pads and rotors. I put new tires all the way around for the new owner and inspected my brake pads with the wheels off. The pads looked about 75% worn and I told the new owner to be safe, he should probably replace the pads in about 10k miles or 2 years and I would help him do it. He plans on driving less than 5k miles/year.

Auto service advisors usually are paid comission and have monthly contests and all kinds of incentives to push certain services. If they can sell you, they make more $$$. Ignorant car owners are their meal ticket. Sadly, deception at all levels has become the norm in most businesses and he who deceives best makes the most. Time more than ever for the consumer to become educated on everything he plans to purchase.

Like other have said...for street driving, even spirited street driving with stock pads the rotors will last a lot longer than 20k miles. If you pad material is less than 4mm then just replace the pads.

You can do this at home in an hour it is so dang simple.

I'm at 65K miles and had car in shop last week, asked them to inspect (I was beginning to wonder) and they said I still had about 40% remaining

Not a heavy brake user might you - those other pedals are where it's at

Over the years I have seen the brake wear to vary considerably between one driver and another. Considerably. (Ditto for clutches). Some people are very hard on cars and their rotor performance can be extremely limited. It's difficult to say what the 'average' rotor wear will be because of the vast differences in braking methods. Personally, I have never replaced a rotor on any Porsche I have owned (and two were above 100K when I sold them).

My rotors lasted 106k km and 8 years. With moderate tracking during last 5 years.
I think I went through 5 set of pads during that time.
