I was addressing Tornado's concern that even with spring there you could push the pedal down to the ground if the cable broke during braking. I don't think ones foot would have that much movement.
I had no trouble on mine with the spring still allowing it to drop by itself.
Thanks Tornado. With your photos the Chinese puzzle is now speaking English-Cheerio!
I installed the spring on my 850 as suggested here in the forums. About 25 miles into my first ride with the spring installed, the brake adjusting nut at the rear of the cable vibrated loose quite rapidly. The road fix was to wrap the rod in electrical tape. Adding a jam nut permanently fixed the problem.
Good to hear your roadside fix and solution. Did you find the spring saved the day?
I think my adjuster rod has a 40+ yrs old nyloc nut...and it turns only a little less than freely. I should at least replace with a fresh one or go with a second jam nut.
Tornado; the nut on my bike looks to be the original nut as well but has lost its retaining ability. Though the nut loosened to the point the brake was seriously affected, luckily, the nut did not come completely off. The applied tape essentially locked the nut in position--improvised nyloc so to speak.
Certainly, if the nut would have come off, the safety spring would have kept the brake lever in a safe position. The safety spring and jam nut are permanent fixtures on the bike.
The older expert who rebuilt my gearbox years ago told me to rub a bit of silicone caulk on any threads I was having “vibratory” issues with , pretty easy/simple fix and effective ... I do use a new nylock on the rear brakes adjuster though .... the silicone is used in hard to see spots
Does anyone know of a company that sells the same spring as AN, here in the states? I like Tornado's comment about a hard stop, maybe I'll look into designing something of that nature as well. If I come up with something I will post it.
I thought the return spring was a good enough idea that I used it on the rear set's brake lever when I switched from the stock foot rests to rear sets. Hooking the brake lever on a left hander would not be a good thing... The spring prevents a potential disaster.
Available in the states... Ebay search "Norton Brake Safety Spring". Several show up.
I got mine from Walridge Motors.
Rich Harrett insisted that I buy one from Walridge at the Toronto Supershow a few years ago. I installed it. Fortuitous. The nyloc adjusting backed off when I was blasting home on the QEW from the CVMG Paris Rally a few months later. All the hardware at the end of the cable gone. Hate to think of the excitement if I didn't have it.
this why i like to double nut the adjuster.
I did look at my brake lever yesterday and I see it would be very easy to make a positive stop , however I think I will just go with a spring. A very good insurance add.
I actually loved when this came along. I had converted the rear brake to disc via MK3 hardware and a Performance Machine m/c on my '71 . Their return spring was pretty ugly and this was a much neater solution. Put one on my '73 850 as insurance for all the above experiences of cable hardware failures.
Cheap insurance for sure.
