BSA Triumph Conical Hub Brake Twin Leading Shoe adaption:

Posted by john_hall1 at August 12. 2017

Hi,

Does anyone know whether the later 8" BSA/ Triumph Conical Hub Twin Leading shoe brake plate unit and shoes, can be adapted for a Dominator full width 8" drum?

 

Cheers

I have a brake from a 1968 to 1970 Triumph/BSA on my 99.  I've asked the fellow who made the mod if the conical one could be fitted as well.  He fit one to his RE Interceptor.  I'll let you know.

Unfortunately he is currently too busy to provide much of an answer but it doesn't sound good.

 

"I've looked at using the conical brake, but there was a snag which I can't fully recall.  Seems to me that it was a clearance issue with the hub, or in arranging an abutment for the torque stop peg."

 

I might be able to get more out of him in a week or so....

The Tri/BSA conical hub brake didn't have a particularly great reputation. Not generally thought of as better than a Norton TLS setup. Is it worth the effort?

Agreed Gordon.

They weren't known as 'Comical Hubs' for nothing {#emotions_dlg.smile}

I have one fitted to my BSA Triple, many owners of these bikes upgrade them to a disc setup but I wanted to keep the 'authentic' look of the bike. When purchased the comical front brake had very little retarding affect (downright scary!). I changed the brake linings, had the drums skimmed and fitted 'Mutz-Nutz' brake arm extenders. After careful set-up the brake actually works quite well. Opinion is that the earlier BSA/Triumph full-width TLS of the late '60s was a much better brake - better than the Norton TLS design fitted to the early Commandos.
