[QUOTE="Peter Holmes, post: 50083, member: 302"] I remember a friendly and amicable discussion taking place at the West London Series D meet a few years ago, our now section leader, and very talented engineer Paul Packman was there with his magnificent Vincent Rapide sporting his own beautifully engineered TLS Front Brakes, also there was another extremely talented and clever engineer and Vincent owner from Basingstoke, Roy Cross, with, if I remember correctly a Series D enclosed Vincent sporting a beautifully engineered, fairly huge twin disc set up. Initially the discussion that ensued was about looks and originality, or should I say as close to looking original as is possible as well as improving the brakes, I think in that objective Paul achieved success, on the other hand Roy had brakes comparable to any modern machine but lost out a little on the originallity stakes, having said that I thought Roy's set up looked really good and in keeping. But then the discussion turned to grabbing and locking up, Roy was of the opinion that due to the self servo action of the TLS that grabbing and locking up was inevitable to the point of being dangerous, Paul disagreed. I have no idea who and what is right or wrong. Twin leading shoe brakes have been around for a very long time, I am not an engineer so I have to guess at things, but my guess is that the strength of the pull off springs is of paramount importance, one of my vans had some work done at a local garage and the rear SLS drum brake shoes were replaced using the incorrect springs, the results of that were quite dramatic, you could be driving along when suddenly, without even touching the brake pedal, there would be loud bang and as the rear wheel or wheels locked up the the van would sqat down, fitted the correct shorter pull off springs and never had onother problem, fitting the wrong springs or having a spring snap on a motorcycle front drum brake I would imagine could be quite scary.
