306 XTDT ATE caliper - guide pin removal

I need to replace the front discs on my '94 306 XTDT. The ATE caliper is
help in place by two guide pins. Can anyone tell me what size socket I
need to remove these as they are surrounded by a dust shroud and I can't
see how to get them out!

Any tips for replacing discs?

Thanks

Simon

I'm not familiar with this vehicle but this type of shroud should have plastic
end caps which prise out and then normally there's an allen key hole in the end
of each pin.

 

Correct. And the allen key size is 7mm.

When repalcing discs make sure the face of the disc carrier is
perfectly clean and put a little copaslip on the face where the disc
fits around the carrier.

 

which is usually 7 mm

Thanks for the help everyone!

Got the right Allan key, but can I shift the buggers? Not a chance! Any
advice on removing siezed guide pins? (I presume they untighten
normally, i.e. anti-clockwise).

Pull harder. I use a 9" length of 22mm copper central heating pipe over the end
of the allen key to increase the leverage but any bit of strong tube will do.
Yes they undo a/c. I hope you aren't getting your a/c confused because they
point away from you. It has been known.

 

probably misunderstood but don't you just undo the 2 x 17mm bolts and lift
the caliper off the disc to replace the pads.....
