Bought my first Porsche three weeks ago, base Carrera with 35k miles. I'm learning the car and noticed the brake calipers are different than those on other Porsche models, the basic difference being to change pads the calipers have to be removed. The question I have concerns the four pad guide pins that pass through the caliper. There are four on each caliper, two inboard and two outboard. Mine are corroded so I thought it'd be easy to replace them. I have two problems: 1) I cannot find said pins in the .pdf parts catalog or at the various parts vendors I've used in past for BMWs. 2) These pins have what appears to be a triple square head, and I haven't been able to find a female socket online anywhere. Can anybody spread some cheer?

 

standard 12 point socks is all you need. Available at any hardware store

 

Hmm...I have those and just checked. 11mm too big, 10mm too small. Hard to believe it's not metric, but will have to try something in inch. Perplexing. Small world - I was born in Fargo.

 

Sears comes to rescue with a 9-pc universal metric socket set (p/n 92496) for $17. Works with several fastener types including this one. Car doesn't need brakes now; this is first Porsche for me after string of nine BMWs so I'm in learning mode. Calipers on this base Carrera are different from those I've seen on YouTube DIYs and other online pictures. I've not been able to find them in the Porsche parts catalog.
