Rusty discs

[marlin]

Does anyone know of a product that removes moister but doesn't leave a residue. Its the rusty disc syndrome that's the problem. Now its coming up to gritter time, I want to wash the car and maybe not use for a couple of weeks. The best option is take for a short run like many do but I live on a bridle way that's pot holed and muddy in the winter, so one run out and the car gets dirty again.

I spray it on first, then wash the car.

You are probably aware of this but most disks fail on the corrosion on the inside of the disks--not where you can see them----I keep my cars in a garage with a dehumidifier--if the cars come in wet if put on a fan to circulate the air around the car to reduce the possibility of corrosion.

Similalry talking to a couple of R7 members at the weekend many drive and revenrse the car up and down the drive applying the brakes as much as possible to dry them off. This is better than just leaving the car with cold disks.

Funny you should say that. I've just had a 4yr 30k service on my S at the Tonbridge OPC. What did they have to advise me? Corrosion on the inner disc faces. 'Would you like us to replace them sir?' I think not!

My car has just sailed through its MoT only two weeks ago. 'How are the discs and pads' I asked?
'Absolutely fine' I was told.
The car brakes solidly and cleanly with not a hint of judder.
I wonder how many people put their car through an OPC service without an adverse comment about discs or pads?

I'd heard from other Boxster drivers that brake disk corrosion was a common problem, so when I recently took my '04 Boxster S 550 for it's 3yr 24K service it came as no surprise that the service dept at Nottingham OPC advised me that all four brake disks were showing signs of corrosion and should be replaced sometime soon - at a cost of £1300 !!! (maybe not).

Interestingly, the car also had it's first MOT on the same day and the only thing they reported was "front tyres near limit", (now replaced) and "slight scoring on brake disks".

Me thinks OPC's might be on to a nice little earner []

Its a common problem on the inner faces of the discs, a lot of garages have a brake skimming machine that will skim the surfaces of the discs in situ,
I used Auto2000 in Bedford for this service on my wifes Boxster,, I think it was about £50 an axle.

New disks are around £30 each from Eurocarparts so why ever bother skimming?

And it's a very easy DIY job.

Having given my car a thorough spring cleaning over the weekend I too am suffering from rust on the inner surfaces of all 4 discs, having read the numerous threads on the boxster and 996 forums am more than happy to undertake a DIY replacement of discs and pads.

There is a massive variance in price between the different brands, OEM discs from euro car parts are £98, the others are cheaper but I'm not sure about quality. That said the discs on my car are original Porsche but they've lasted only 30,000 miles and nearly 4 years. Should I be expecting more than this.

What is your experience of using non Porsche discs pads.

All comments welcome,

Sebro disks and textar pad combo....

If an 'S,' I think the rear disks will have to be Porsche, but I would love someone to say otherwise!

What he said[] (front and rear)

4 years on disks is good going in my experience. I'm sure some others will tell you they are still on their originals 9 years later (you know who you are[])

I've twice been advised to replace my rear discs by OPC and had them skimmed at specialist at a fraction of the cost. The car has just been inspected for trade in at OPC and guess what, 18 months after skimmimng and 12 months from last service thay have costed to skim them as part of the refurbishment process - its a scam by the OPCs!!

I bought my Front & Rear Disc's from OPC.
You can knock off 10% of the Prices if your a PGB member.

986.351.401.05 Boxster front disc £78 +vat each
986.352.401.04 Brake disc rear boxster £96 +vat each

My Boxster now 4 years old, I have just replaced the front disc and pads and I very happy with them.

I haven't replaced the rear discs yet because there within tolerance, but should last another year or so before I need to replace them.

But should I have bought them from Berlyn Services (Independent supplier of Porsche parts) for 1/3 the price ????

Are these the same as the OPC ones, they look the same to me !!

Here's a picture of my rear disc, not too much rust on the inside after 4 years use.
The inside part of the disc is for the handbrake shoes.

Surely the best way to keep the discs rust free is to use the car ?
I use my Boxster every day- this must keep the rust down.

 

[Bluebox]

A good tip is to always take the car for a short run to heat up the disc's after washing the car.
This helps stop the disc's from rusting or just driver very fast all the time.[8D]

My 24,000 mile Boxster 3.2S is used every day and I usually take it for a run around the block after washing, but I still got corrosion on the inner faces, (and a bit of scoring). Advised by OPC to replace disks, (see earlier thread), but had the disks skimmed instead by "Autotune TVR" near Hinckley. (www.autotune-tvr.co.uk). Took about an hour per wheel and cost £200 for all four. Everything now seems good as new.

What is it with Porsche !! I have never had this problem with any other car which had ventilated discs, Meguires recommend washing the car, taking it for a drive and then cleaning the wheels again with their mild wheel cleaner.[]

 

[InnerSphere]

I agree - It's a real pain washing the wheels twice. Once to remove brake dust, grime etc, and again after taking it for a drive because all the rusty stuff from inside the discs has sprayed itself all over the wheels.

The person who finds a permanent solution for this will become rich, I am sure of it []
