Brake pad change

[DC Concours]

Does any one know the hex size of the rear caliper bolts. They look like 8 or 10mm.

I misplaced my larger hex drive adapters. Anyone replace them with regular bolts like the fronts calipers?

From memory they take an 8mm Allen key.
No reason why you couldn't use regular hex bolts but you would need to use ones with pretty large heads or some hefty spacers as they would be transferring the load to a weaker part of the bracket.
Probably easier/cheaper to just buy some more hex adapters. Personally I always have a couple of cheap sets of Allen Keys to hand as well as the 1/2" socket ones.

Thanks Boomer. I don't use hexes for much. For the bicycles and furniture mostly and they are never as large as the c10 calipers. I buy the bigger bits as singles because I never use them. I will buy a cheapo set from Harbor Freight.

Changing the bolts over to 10mm like the fronts would be great but as you said I need to make sure the bolts are properly shaped, rated, etc. And I don't know all the ratings that come with bolts. I remember someone mentioned sheer rating technicalities when discussing the sacrificial bolts on the tipover bars.

I am getting EBC brakes. And they are pricy.

Anyone have experience using the less expensive generic C10 pads sold all over amazon? The reviews are not bad.

[Boomer]

Goldfren and Armstrong are garbage, not tried most of the rest.
Carbon Lorraine were OK, SBS HH are good, EBC HH are good.
I mostly use EBC HH pads for the rear of the C10 but the GGs give a softer initial bite.
They are only $35 for the EBC HH pads or $27 for the EBC GG Organic pads.

You are right as usual. It is 8mm.

The fiche says 92002-1713 BOLT, SOCKET, 10X17

Is the 10 for 10mm diameter? Shouldn't it say 8x17 ?

Convention is confusing here. Is JIS different?

[VirginiaJim]

The Japanese standard JIS is a bit different from our Philips screw drivers.

10x17 means that the bolt shaft is 10mm diameter and 17mm long.
It make no reference to the means of tightening/loosening the bolt other than "SOCKET" which indicated that it needs an Allen Key.
If it had said M10x17 then that would imply 10mm diameter shaft with a 1.5mm thread pitch.
As it is it doesn't specify the thread pitch at all.

Japanese Industry Standard (JIS) is their equivalent to ISO or ANSI.
On our motorcycles and cars the only time we come across JIS stuff is with their "equivalent" to the Philips screwhead.
To be honest JIS screwheads are just 100% better than Philips and should be adopted as the ISO world standard, but then getting people to agree on such a change would be harder than negotiating a lasting peace in the Middle East.

How do you know all this sh!t Boomer?

Great information. I appreciate the new knowledge I gained. Thanks.

<LOL> I'm naturally inquisitive, I fix stuff for a living (mostly software these days), and I'm nearly 60 so fairly experienced.
I grew up with Metric and Imperial measurement systems.
Imperial (British) is awful and the US measurement system is very closely tied to Imperial. It's inconsistent, requires endless conversions and includes several competing "standards" in engineering.
Metric is easy to remember, work with, and understand, and there is mostly only one "standard".

Oh my....

[Boomer]

Oh my....

Now is that hex bolt you want to remove a Whitworth, or a BSP, or BA or UNC, UNF, BSC,..... 
Is the head of the hex bolt measured AF (across flats) or AP (across points) so you can determine what wrench (spanner) is required? 
Metric is easy. About the only exception I have ever encountered was an M8 bolt with a 12mmAF head. Most are 13mmAF.

My head hurts.

[VirginiaJim]

I'm with you on that...

[Boomer]

Mine overflowed years ago.

[VirginiaJim]

Still right much left though...lol

[DC Concours]

Yup. You still have plenty left to overflow ours. Go easy on us.

My brain now operates on a FIFO method (First In, First Out) so whenever I learn something new (happens many times per day) I also forget something I used to know, or at least it feels like that. One of the Belgian GTR guys (Raf Sonck) stayed with us overnight on Tuesday night and we had a few beers and reminisced. Whilst chatting I found that I couldn't remember the address of the old COG Listserver which I used to have memorised. Rick probably still remembers it but I can't for the life of me remember it, and I used to help admin it a little. Chances are Rick would mention the name of the listserver hosting company/website and it would all come flooding back so it's probably all still in there but there is so much other junk I can no longer find it.
My head hasn't exploded but I seem to have lost the address book to parts of it 
However, I can still remember the tag plate of my Dad's old Volvo 145 from 1972.
