I decided to ogive my 924S's brakes an overhaul - I do a very low c2k miles a year, and I had the whole system overhauled a few years ago. I remember the mechanic then had to drill out & replace some of the pins.

Anyway they all came out bar the O/S/R ones and one has been damaged and is now too short to fit the R clip in the end.

I called my local Porsche dealer and they are £45 for an exle set

which even he admitted was " a bit pricey for what it was"!!

Does anyone know where in the UK I can get these cheaper, they seem to be made from ATE. I only need one.

Made a mental note to check the brakes more often!!

The calipers were a bit stciky as well bit I freed them up with spray grease at the slider part.

Its funny how being short of cash suddenly makes you inventive. While I was pondering the problem of my "too short" brake pad retaining pin, I noticed that its dimensions are very close to that of the humble 6" nail. I measured the diameters with my Verniers and the Porsche pin is 7mm at the outer end and 6mm at the inner. The nail is 6-6.5mm along its length. I test fitted it in the caliper, and the nail slid through the outer end but was too fat to go through the inner. So I cut it down to the right length, carefully filed of the right ammount of girth and then drilled a hole diametrically through the end for the R pin. Greased it up & popped it in - fits a treat with no play. Job done - cost "nil".

I suppose if I had been wanted to go the whole hog, I could have welded a blob on the head to give it a slightly domed appearance, but you can hardly see it under the telephone dial alloys.

I suspect that nail's sheering strength is much less than the stock pin.

I wouldn't worry about it. The caliper is what holds the pads and takes all of the side movement. The pins just keep the pads in place so they do not come out of the caliper.

Hi Paul, the original pins are not that strong - one of them noticably bent while I was removing it, and I had to straighten it out in the vice!! As v8carreragts says the caliper takes all the load on braking and the pins merely hold in the pads. Funnily enough I noticed that while stripping down the brakes that one of the front caliper R pins hadn't been replaced when it had been in the garage a few years ago and the pin hadn't moved at all during the intervening years.
