I am also thinking about a better front disc brake setup for my stock 1974 850 Commando. It has rear drum and the lousy stock front single disc . Any ideas on a good aftermarket setup or something I could pull from another bike that will stop better??? As usual all of you have been very helpful with the great info and I really appreciate it---Mark Cigainero
 
I converted my 1973 to the 1975 MKIII rear disk brake. It worked awesome. As for the front there are kits available for a floating 13" disk. And some for dual disks.
 
Using Google I think I found a picture of a 1774 Commando...

Better front disc brakes for 1774 850 Commando


:mrgreen:

It looks like it could benefit from some disk brakes...
 
I had the master cylinder sleeved, installed braided steel brake lines, and rebuilt the caliper on my '73 Commando. Made a major improvement in the brakes, retains stock look,and wasn't very expensive.

But seriously a quick search will find endless threads on how to improve the front brake.

I'd agree. It's mostly the master cylinder where the front disk falls short. If you improve it or replace it with a Grimeca or Brembo. You'll have nearly the stopping
power of a modern disk.

Colorado Norton Works. The very best front brake upgrade. Keep your rear drum. You shouldn't be using your rear brake anyway .
 
As has mentioned before the Brembo master cylinder gives superb results, I used the standard disc set up and replaced the original lever and master cylinder with a brembo item and it works fine. For ultimate braking ther are lots of other systems available with floating disc,from Norvil etc or Mick Hemmings can supply a fork leg and disc etc(Norvil) as fitted to the original Proddy Racers.
 
Resleeve the master and install Ferodo Platinum pads. If your brake lines are older than 5 years replace them too. Cheap, quick, relatively inexpensive and more than adequate if you stay within the rational performance envelope of your classic machine.

true for 99% of the threads, but its so much easier to start a new one?! :mrgreen:
 
I opted for the Brembo MC from CNW for my MKIII and also fitted their switchgear. I am still running the stock Caliper/Rotor and the brake is now as good as my Hinckley Bonnie, I am very satisfied. Have any of you guys fitted the sleeved down MC for the rear brake on an MKIII, I am interested in this mod and may need to start a thread.
 
Hi, I would use the standard front master re sleeved to 13mm by Miles Brakes along with his replacement front rotor. Lots of stopping power and the front replacement rotor looks way cool.
The rotor of course is the same on the MK111 rear and Miles also makes a 13mm stainless barrel replacement for the rear MK111 brake cylinder which is the same as the Triumph master brake cylinders front and rear.

A Brembo rear master cylinder with remote reservoir is a very easy adaptation. And they are available quite cheap.


Better front disc brakes for 1774 850 Commando


Of course, I also like to scrap the heavy Norton caliper and disc for a modified Ducati caliper mount, Brembo rear rotor, and Brembo rear caliper. Saves a ton of unsprung weight.
 
With reference to the Norton rear drum brake.
Years ago I converted a BSA B33 sls front drum (Ariel) to hydraulic using a BMC Mini slave cylinder.
I can't remember what handlebar unit I used but it made a great difference to the stopping distance.
Perhaps somthing similar could be done to the Norton rear.

Hate to disagree, but id say its earlier due to the unpainted barrel, and frame mounted center stand.
 
You are such a funny guy---Thanks for the laffffffffff-------
