Post subject:  Cooper S Disc retaining pins

Hi all,

I've got 2 sets of disc retaining pins from 2 different Mini suppliers and both are too large to fit thru the calipers.

Are my calipers normal???

Disc casting has

3242*13
LOCKHEED
*A21241

I think * is 8 (hard to read)

one set of pins are Unipart GBK 1010

Cheers

Are you talking about steel pins? S calliper pads are held in with split pins, not solid steel pins. You can get the split pins from most nut & bolt suppliers, there roughly 1/8 x 65mm.

Yeah split pins are what I meant, I've got 2 sets from 2 different well known mini suppliers and both are 2 big so starting to wonder if its my calipers that are different.

They should be 1/8" diameter- sadly these are getting hard to find. Not made here anymore....
Everybody wants to supply you cheesey 3mm ones from PRC.
Beware- these are soft and weak, you can bend them with your fingers- and if they break/wear through you can lose a pad like I did. Scary stuff!

I now use 2 bits of 1/8" (3.2mm) dia welding electrode, cut 80mm long, with the ends bent over.

OK, Thanks heaps Doc. I like your idea.

The split pins I have are definitely bigger than 1/8 inch.

I have noticed that in recent years they just give us the wrong pins. A little while ago, they were too short, now they're too fat. I do similar to the Doc.

When our friends in PRC and other "manufacturers" on the sub-continent learn how to make quality fastners, maybe they'll start using 'em themselves................

GBK1010 or BFK760 are for 8.4" calipers and won't fit Cooper S ones.

cheers.
