All but brake cables are made from DIY lengths from a friend
who restores bikes professionally. The brake cables I make from
inner and outer I bought a long time ago from a place in Sheffield.
It is slightly larger than standard, enough so that standard ferrules
don't fit the abutments on brake and handlebar. I have a number of
ferrules made up to accept the cable at one end and to fit into the
abutment at the other although I've modified some of the handlebar
controls to take the bigger ferrules. The outer has a wire winding
which is much finer than modern outers and the inner is a much closer
fit too which means that nipples have to be modified as well.
All are soldered with a soft solder and an electric iron and I take a
lot of care with opening the inner wire end out to ensure it can't pull
through.

The brake cables don't seem to wear anywhere nearly as quickly as the
modern cable - the handlebar nipple will wear before the inner.

On my wish-list: a solder pot and a tool to open out the end of the
inner - these have been described in other posts.



OK time to get the soldering kit out.
It may also be possible to buy nipples/terminals that have a grub screw or even 2 g screws that will fit the lever or pedal gear.

For what it's worth I've never had any success with solderless nipples
and would not contemplate using them on anything brake-related, at all.

And I'm not sure I can remember one of them doing that very well either!

I usually have one of those in my wallet, you can fix clutch cable, if it brakes.

I always have a selection of solderless nipples in my jacket pocket. I can't remember using one on my own bike, probably because I carry spare cables in the toolbox of each bike, but fellow riders have used them from time to time.

I fitted a BSA 8" sls DRUM AND A hONDA cb72 brake plate that has heavilly modified shoes to account for 8" not being 200mm. I will get some bespoke brake shoes machined up at some pont as the lining gets thin in the middle when turmed to match the bigger diameter drum.

OK. Yes spare cables in the toolbox. That the sensible way to approach it.
Thanks all for the tips.

Hi folks -
(David) "I Imagine stopping a SQ4 with one of these 7" HWH brakes can be interesting at times."
Perhaps "interesting" is not the best descriptive of a Sq4 brakes... I'd use (expletive) horrendous / disasterous / appalling or similar!
Problem is we're all now used to twin discs with multi-pot Brembos & anti-lock... & motorists & pedestrians also expect us to have such...
If you can get hold of one; - the 9" (230 mm) FW 4LS double sided Grimeca is the absolute dog's danglers - & requires no mods at all to the teles.
Take proper care on the set-up - feather all LEs & TEs - tweak tie rods appropriately... etc - SUPERB & doesn't look too* "out of place".
*(with apologies to the purists)
(Simes) "The (Sq4) back brake is pretty powerful" ??? we'll agree to differ on this one, but with the Grimeca up front the back brake is become superfluous.
Cheers, John
