Replacing brake discs already???

[Guest]

Newbie here.

We have a 5 year old Boxster S with 42K on the clock.

It has supposedly never been tracked by us or the previous owner but now needs 4 new brake discs due to wear.

I have no real knowledge of Porsches, but have never known another car need rear discs within 42K especially as much of those are motorway miles. In fact I don't think 42K is good for front discs really either.

Is this common for a Boxster?

TIA

I bet it is corrosion wear rather than wear out of usage; my front discs needed replacing at some 23K mileage and at 3years age, so you have done well... Is it kept in a well ventilated garage? Do you drive it straight after cleaning? Do you make sure the discs are reasonably dry after a rainy drive before storage? You should. I'm afraid this is common on all modern cross-drilled discs and much so on low mileage cars i.e. the ones that are not used everyday.

Thanks for the reply. It is garaged and is driven after cleaning. But we live in NW England so getting the discs dry before storage is not likely to happen. It is treated no differently to my Subaru which has double the mileage and is still on the original discs so are you saying the cross drilling causes the corrosion as that is the only difference I can see between the two car's braking systems. Not doubting you just asking as this is all new to me. Thanks.

I wonder how much this is the dealer network trying it on? We need to reach our target this month, tell the customer his disks need doing and he'll say yes because it's a safety issue.

Not specifically blaming OPCs (nor saying they are just ripping off the end users...).

My 20k miles Toyota has just been serviced and when I collected they said "we changed the disks all around sir, under the warranty , pads were fine but obviously they had to be changed too, warranty pays it all"

What!? at 20k miles? "Corrosion sir, it happens".

Great - but almost unbelievable that the manufacturers don't solve the problem. Shame Porsche don't give a 3 year/100K miles warranty....

My other Toyota (138K) is serviced at an indy and, strangely, stopped having problems with it's disks when I stopped using the main dealer to service it....

Thanks for the reply Mark.

I would agree but have taken the car to a friend of mine who preps rally cars and runs a small perfromance car garage and he agrees they are done for and need replacing.

My real question like his is how can this happen at such low miles. I will call him and ask him if he feels it is corrosion rather than wear, but he doesn't deal with Porsches often himself and it was his idea to post on here.

I get the impression he feels something is not quite right somewhere.

Thanks.

Buy the 'Textar and Sebro kits' from Design911 for replacements.
