Pads and discs, cost?

So, to bring this back up, my car is in for it's four year service and the brake pad wear sensor came on recently.....just had an email quoting me;

"Front Discs and Pads £920.14"

£920 seems steep just for the front pads and discs!?!?!?

At around £200 for the parts its ludicrous.

Indeed!!

[Sarnie]

Ok, so it's extortionate.

But my car is in warranty and want to renew it next March; what are my options? Can you get OEM parts elsewhere or am I resigned to paying the OPC price to keep the car 100% OEM?

Thanks.

So where do people buy "correct/oem stuff"?

So are these Textar discs OEM as it states?

is this for your R Sarnie? Why the heck would discs need replacing for a 3-4yr old (orinally £60K+..ie well engineered) car? Pads are a consumable but discs should last 5yrs + (if not more) unless they had been spanked around a track or left out in all weathers.
Dealers telling you your discs need replacing is the most common con trick amongst all of the big players and that price quoted by the OPC to change them is a farce. I would much rather use a respected Porsche specialist like Jaz etc who have a reputation to protect and will do the best job at a third of the cost, using the correct parts.

The back of the discs are prone to rusting and consequently an MOT failure. I can pretty much expect my car to fail on rusted discs (either front or rear) just about every other year, and I'm only covering about 5K miles a year. The car is kept outside which I'm sure contributes though.

This, I only do 2.5-3k mls a year & mine are changed every 2-3yrs as a result of rusting on inner face.

eh? is it a design fault on the cayman then? Pretty sure all Porsche discs are made from the same (assumed quality) steel! I changed my discs on my 911 4-5 yrs ago, they've done about 40k miles, umpteen track days and euro tours and never failed an MOT in that time, nor be commented that they should be replaced or an advisory. Always used trusted people for servicing etc. and car even inspected by the PCGB technical adviser. Wonder how quickly that diagnosis would change if I went to an OPC?
What sort of rust are we talking? Must only be surface discolouration rather than pitted steel? Think you guys are being taken for a ride, I hear the same thing trotted out from people taking their cars to VW, BMW, Volvo etc, all the main dealers. Plus the price to do them is just a fleecing-exercise as its an easy big-ticket item.

This is not an OPC in my case but a trusted indy. We are talking about serious scoring and pitting of the rear of the disc face and the resultant premature wearing of the pads. Apparently it is to do with the back plates and the relatively enclosed nature of the rear of the disc which when parked up wet, does not dry out quickly and results in rust. This is of course accelerated during winter when the roads are salted.

Mine is a 996 not a Cayman & again, respected Indies not OPC. Last time I took up the invite to be shown the discs while the car was on the ramps so I know I'm not being taken for a ride.

The fact that yours do get used a lot would suggest why they have lasted so much longer

[MJ911]

interesting to know, thanks guys. Trev you had best start using your car more ;-)

[MJ911]

from what Trevor is saying it sounds like 'light use and low miles' is whats causing his problems!
Regular good use seems to keep them in better condition based on my own experience. Car is garaged as well though which also helps I expect. Every 2yrs sounds ridiculous to me for disc replacement, but each to their own.

It hasn't made any difference in the past tbh. I used it as my daily (60 mile round trip) for about three years and still suffered premature rusting to the discs. AFAIK the problem starts when the car is parked up after use in bad weather.

Just found this thread I started about a year ago when I had the fronts done last.

My disks are starting to develop a lip, can anyone suggest a reasonably priced micrometer I could purchase to keep an eye on them?

A quick look on Amazon shows plenty of micrometers that deal with a maximum of 25mm, but according to what I've read, the front disks on my 996 have an operating range of 28 - 26.6mm

Given the tolerance you have to work with it would be easier and cheaper the use a set of OD calipers.

Rust on the inside faces of the discs can be very severe. The pic is of my Cayman discs which had done about 20k miles. Despite the fact I religiously dry the discs off every time I wash the car, I've come to the conclusion that the problem is down to not getting enough heat into the discs to properly dry off the water directed at the rear faces by the cooling ducts on wet journeys.

I'm now trying to make sure I get more heat into them, especially just before I park up in my garage at the end of the journey. Time will tell if this works!

[Schermerhorn]

Get the discs skimmed (if enough surface material left to work with) and some original Porsche pads and wear sensors from the deal?
