Hi Everyone,
I am hoping someone can tell me the exact length/part # for the front brake cable on a 1951 a10 Plunger? Regards Ian
-
G'day Ian.
A10 cable is 67-8610, the A7 is 65-8675
I didn't realize they were different. Now I'll have to find out why.
Cheers

Hi Musky,
It might be something to do with the A10 having an 8inch brake and an A7 having a 7inch.....only guessing!!
Sorry I can't answer the original question Ian.

Probably an academic question, it depends on which handlebars you use.

Just measured my '51's. 2'10" outer, + 6" of inner.
Cheers

Whatever you buy won't fit.
-
Thanks everyone, I will need to check this out. The cable I was using was almost impossible to get the right tension setup on the front brakes...
I just finished a complete rebuild after a seizing a timing side bush :-( Shall post some pictures some time today.

i am running into same problem my 51 did not have front brake cable purchased one from baxter and i measured mine and is about one and a quarter inches to long with measurements muskrat gave cable itself is forty one and a quarter.
-
The inner is 1 1/4" too long, or the cable itself is 1 1/4" too long?
Time to fire up the soldering iron and remake the end.

Rex - obviously an option tho gets me anxious soldering a brake cable. if a throttle cable breaks it can spoil your day, but if a brake cable breaks it can spoil your life. Ian if you do solder it, at least clean it very well, make a decent 'birds nest' and use a hard solder (silver solder).
for minor front brake cable length problems I've used additional cable tensioners and spacers to avoid soldering.
-
I've never hard soldered a cable, but then I've never used a blow torch when soldering a cable either. A 75W electric iron is more than sufficient.
Spotless cleanliness, a good flux and a well-flared cable end...all absolutely essential.
As over-the-counter cables never seem to fit either well or at all, it's a worthwhile skill to learn. Nothing worse than seeing a new cable with it's adjuster would out to it's max in an attempt to make it work.

Wouldn’t hard solder result in an annealed cable? I use plain old (soft) plumbers solder and flux, and a gas torch, it would have to be pretty high wattage electric iron to do the job.
The secret to making a good brake cable is to use the proper materials and properly splay the ends of the wire into the recess provided in the fitting, or make a “birds nest” as mikeb said, also as mikeb said this is not a job to take on lightly, it would be best to have someone with experience show you how to do it first.
The spline the brake lever is fitted onto affects the length of inner “showing’ and is a reason cables often won’t fit without modification.
Another tip, use a dremel with cutting disc to cut inners and outers. It does a great job.

75W is 75W and even that can get the nipple hotter than it needs to be. I guess we all have our own pet way of doing things.
Regarding the idea of "knowing what you're doing" that applies to many aspects of bike mechanics, but most of us seem happy to trust our own skills to a greater or lesser extent.

Some useful relevant information in the above thread, I thought.

Kiwi - i use a 70W soldering iron that adjusted to about 450-480F which melts silver solder well. not a torch. its only needs to be a little hotter than the lead/tin melting point.
each to their own, as they see the risks and benefits, be it soldering cables or winding out adjusters

haha Rex "knowing what you're doing" this doesn't apply to me when i'm working on the yonda *whistle* *bash*
