Why would you want to use old pads when changing your discs?

A strange false economy IMO

I wouldn't normally and you're right. Just finances really and I'm not afraid to admit it. :)

Agreed. But if you have not got the money then it doesn't matter how much they cost. I won't be scrimping on these in any case, but the question was mainly to do with whether I needed to change the pads or not, considering they are only 50% worn!

Having said this I'll also change the brake fluid as I believe I may have cooked it. :)

I apologise if you'll hate me for saying this but - you've got a 997 version of a 911 - in my opinion, try to re-use brake pads that are likely to be less than UKP100 per axle is false economy. Re-use the wear indicators by all means but old pads on new discs is more risky than cost effective...

Gary,

Whats is the issue with leaving the current pads on the calipers, if there is plenty of wear left in them. I admit if you are using the services of a garage then I'd certainly agree with you on a cost issue.

However, provided a little care is taken to ensure existing pads and new discs are bedded correctly I see no problems.

Is it a bedding issue to which your comment refers.

The issue is that the surfaces are formed by the state of the discs themselves (e.g. "the bedding-in process") and *any* unevenness or grooving or bias in top or bottom of the pad will be transferred to the new discs. Worse case scenario is that you mess up your discs (heat spots, warping etc.) such that you need news ones really quickly. Better case is that you have inneffective or uneven braking for a while (until the pads are "adjusted" to the new disc).

I just think that for the price, the risk isn't worth it for me. However, I do change my own pads and discs (always have done - right from my first Austin Maxi through all the BMW's and Porsche's I've owned over the years including my M5 and 330CiC).

Best,

Gary :)
 
it's unusual that the discs have worn out but the pads haven't? Normally you would expect to go through 2 to 3 sets of pads per disc change, how come it's out of sync?

gsf do textar "OE" pads but stay clear of their ATE "OEM" discs imho

Thanks all.

Darren, I'll give em a try. Thanks. :thumb:

Gary, no offence taken at all, as what you say is sensible. The pads are not second hand per se', but, there "may" be an issue with bedding in and I'll take that on board. I'm getting prices ranging from £90 to £150 for the pads so it isn't too bad and don't mind changing for the lower price (if they are original Porsche parts)

I was enquiring to see if it's an issue to leave the existing pads in based on the fact they are hardly worn. (50% wear in 35,000 miles. What do I need brakes for!) I'm just trying to establish if it's "crucial" to change the pads at the same time. I have never in my life had to change a set of front discs so this is a first for me. Normally, I have just had to replace pads as the discs were fine. Just seems to be a Porsche trait. :)

Thanks again. :thumb:

Interesting about the price (!). I must admit that I wouldn't re-use old pads but then, I wouldn't necessarily put OEM's on. In fact, on my 951 and more recent BMW's (including my M5), I've deliberately thrown out the pads even though there is life left in them to change to a better brand (more bite, less brake dust, less fade etc.). An interesting side-effect is that they have always been cheaper than OEM's by some margin. Haven't done this with the 997 yet but will probably go that route when I have some time and before my first track day (after all, I've only had the car 10 days - my wife would go nuts if I started "working" on the car already!).

By the way: "crucial" - no. Highly recommended - yes. :)

Gary.

Again agreed. Hense the reason I mention I've changed pads on numerous occasions but not the discs! :what:

I don't know why my discs are just about on their last legs, perhaps the few track days and Ring visits just tipped them over the edge.

I was offered Textar tonight by a friend who owns a Porsche Specialist service and repair garage, who exclaims that they are the same pad as the Porsche offering without the name, or price for that matter. I'm tempted to be honest but not sure which way to go.

I did look at pagid to be honest but for the amount of track use I do I didn't think it was necessary.

On reflection the points you make are indeed sensible and perhaps, for piece of mind, I'll get the pads also.

Not sure why one supplier is telling me they can supply Original Porsche pads for £90 and others are £150!
