7 month old GT4, needs new front discs and pads after 1K?
Discussion
Evening all
Just putting this out there in case anyone else has had a similar experience
Vehicle was parked outside in recent storm and following morning, noise from LHS of the vehicle and significant pulsing through the brake pedal. I assumed that potential debris/damage from storm and vehicle recovered on low loader to OPC. There was no flooding, just wind and heavy rain
OPC diagnosis is that car needs new front discs and pads as vehicle has been parked outside and pads have effectively mated/damaged front discs due to moisture and corrosion-Not covered under Porsche warranty
Car is used daily and does live outside at the moment (before anyone says… the garage is full of road bikes, which can’t live outside 😀), but is only 7 months old and has just passed 1K miles. No tracking or anything testing as still running-in
I’m happy to pay for wear and tear etc, but doesn’t feel right that car needs to be locked up in a garage or the brakes will fail in such a short period of time if lives outside
Never had this problem with the 55 or so other vehicles I’ve owned in the past!
Any thoughts?
Cheers

This appears to be a new phenomenon. Mine did it with 425 miles on the clock but luckily it was parked at the OPC at the time in their dealer stock. Basically according to them it had been valeted and then left wet for quite a while, like a good few days, when they came to move it low and behold the pads were stuck to the discs, when they broke away they left lots of pad residue on the discs and quite a big hole in the pads. I would have just taken it for a thorough blast to try to clean it off. However the dealer was having none of it. The pads were changed and the discs mechanically cleaned, (ie sandpapered 
). I kept the old pads as they weren’t too bad and I thought they might be handy as spares. Yes I am a tightarse.
I should have some pictures somewhere.
Steel brakes incidentally not PCCBs.
This is clearly a new thing because I am ancient and had literally hundreds of cars, it’s never ever happened on any of them.

Sounds like an OPC leg lift. I'd send it to a specialist, corrosion can be cleaned off from the rotor and the pads cleaned up.Just putting this out there in case anyone else has had a similar experience

Yep there was a similar thread recently someone with a GT4 had the same brake issue.
Nothing new and not a problem exclusive to the GT4 as any steel braked car will suffer the same fate under the same conditions.
Washing a car wetting the brakes then garaging it for a couple of weeks will result in a similar problem with wet pads corroding the discs.

I always drive my car up and down my road when I've washed it to remove the horrible surface rust (my neighbours must think I'm barmy).
I really do wish that the Porsche coated brakes were available for the 718 as I'd probably pay for that.
As a side note, my wife's Tesla brake discs never rust after I wash the car so they must have some form of coating on them.

I fully agree with this. However the part of the OPs experience and mine, both new GT4s, that is different to the norm is the amount of pad material that is left on the discs. It’s is a hell of a lot! Now that is not normal.
I have a few cars in the current fleet which sit outside and don’t get used for a few days. Two of them in particular sometimes let out an almighty crack sound as I start to move as the pads let go of the discs, ML420, and Renault Megane 275CupS being the worst offenders. However they don’t give any trouble and drive fine afterwards.
This is deffo a new trait to me and probably down to pad material changes I would guess.

Yep, do the exact same but for more than rust. Always wash my cars with Bilt Hamber which removes the rust, drive to end of street and back with hard braking, park up and then wipe down the inside rims with a dry cloth to remove the liquid splashes from the braking. Dries pads, removes excess liquid and keeps rims clean. I know, OCD....Sorry to read you have had this issue.
Personally I'd push back but worst case and you end up picking up the bill, you could have the discs skimmed rather than replaced. That would save a big chunk.
I have read that legislation has changed and the materials have had to change in brake pads. Perhaps this has made the situation worst.
From your handle I presume we live in the same place and I've only seen one GT4 in the dealers showroom whilst I've been waiting for mine. Lovely spec!!

How can a car be used daily for 7 months and only have a 1000 miles on it?
I'm guessing it's been stood a long time between uses, still a poor show really.
Guessing at a quid a mile just in brakes. Can't you take the wheels off yourself and clean up the discs and pads, might not be perfect but it seems unlikely the discs will be actually warped.

Haha, they are having your pants down.It makes me laugh how much OPCs abuse their customers who seemingly keep coming back for more time and time again.

Absolutely no need for new discs that is dealer BS. Mine cleaned up very easily with a bit of sandpaper. There was a lot of pad material ripped out of the face of the pads so maybe a 10% reduction in effective pad area. On balance worth changing. My OPC just fitted new pads, cleaned up the discs and the car was good to go. I was allowed into the workshop to have a look at them doing the job and I kept the old pads so I know what was involved.Incidentally I would just not pay that much for the problem to potentially happed again. I would fit an aftermarket pad which I feel would be much less likely to suffer the problem.
Its potentially becoming a bit of a joke now. Fit PCCB's and you have to change the pads before you track the car as the standard pads just melt all over the discs. Fit steels and you have the pads welded to the disc if you use the car in the rain. I assume this is Engineering progress at its finest
