[QUOTE="davidd, post: 35882, member: 1177"] The brakes are quite good and I have a lot of confidence in them. There are several reasons that I chose to use them. Phil Irving said once that the ratio of the drum diameter to the tire diameter was lower than ideal. The shoes are much better, wider and stronger. The drums are new, which is something I like to do on the front brakes of any racer. Finally, they do not have the geometry error found by Clever Trevor that is in the stock brake plates. I believe that with careful preparation you can make the 7" brakes work nearly as well, but there is quite a bit of work and a lot of testing (and in my case I would have to purchase two new 7" Shadow drums.) On the negative side, the increase in drum diameter causes a huge weight increase and it is all unsprung. This is fine on the Girdraulic, but I would not put one on a Brampton that is un damped if you like spirited riding. I could offset the weight penalty by going to 18" alloy wheels with Dunlops. My tires weigh quite a few pounds less than the 19" Avons, but it would be lovely to have some alloy drums. Four leading shoe brakes are not legal in the class I run in. These brakes are very good for my application. David [/QUOTE]
