Not much different than all other drum brakes, just one question really:

Rear brake lever, the one mounted on the hub, mine is pointing down. I notice on other bikes it is pointing up. Still works down. Is pointing up the prefered position?

any other set up tips specific to these conical hubs?
thanks

On my 72 the lever is up but the book shows it down???
The front brakes on these things are a bad joke. I virtually drove without using it for 15 years as it was useless. Then I found Vintage Brake(vintagebrake.com) and I had to learn how to drive all over again. It's amazing how much more fun you can have with a brake that actually WORKS. And works better,much better,than when it left the factory.

As far as i know. the lever up/down is limited by clearance of the shock by the brake rod. I wish i could get mine pointing up because due to wear the rod/lever angle is past perpendicular so i lose leverage.
As to the front, the brake switch in the cable often causes problems. I got a straight thru cable(as good quality as you can get) and things improved a bunch. the length is important too. Too long adds to the bends and work against you. Get good linings, keep things lubed and the shoes adjusted. I also adjusted where the hand lever is so i'm grabbing it as near to the end as possible to get the best leverage

The difference in the way the lever points is because Triumph lowered the frame in that range of years. If yours points down you probably have the higher frame. Mine points up and I have the lower frame. Mine was built in January 1972 my serial #'s start AGxxxx.

The most important part of getting the conical to stop is to true the drum after the wheel is laced up, and to then radius the shoes to the drum. That being said, I'm starting to think this may not be the bike for you. Triumphs have many quirks, and making the bike perform well within their limitations is part of the fun. If it's not fun for you, don't do it.

A few years ago, a buddy suggested extending the actuating arms by 1/2 inch to get more leverage. I have a 71 that I am tempted to try it on.
Has anyone tried this?

I recently bought a '72 A65L from a friend that had it for 20 years. He said he never used the front brake because it was practically useless. Having owned a B50 with an excellent front brake for about a year, I was pretty sure there was a simple reason.

I took the Lightning's brake apart and found oil or grease contaminated linings. Being cheap, I tried cleaning them with brakleen and arcing them to the drum with sandpaper, but the brake was still terrible. The shoes were so contaminated, the oil came back to the surface. Installing new shoes transformed the brake.

When I first took the bike out for a test, I hear this squeaky noise that I hadn't heard before every time I hit the the brake. I couldn't figure out what it was, but it was braking so well I didn't really care. It turned out it was the tire chirping.

On extending the levers. I too have heard that and one of the advertisers on this site sells them. For about what they cost you can have Vintage Brake do a proper brake job.
