Improving Drum Brakes
Improving Singles & Dominator Drum Brakes
The Dominator/Single Cylinder models had a simplex front brake, that can be changed to duplex operation by replacing the original brake plate with the Commando brake plate
06.3281
Improving the early Commando Front Brakes
Commando Front Brakes were built without the "Stiffening Kit" before the 1972 Model Year. The Stiffening Kit
06.3410
doubles braking power- at least that is what several customers claimed after installing it in their Commandos.
In our Brake Plate Assemblies
06.3281
these Stiffening Kits are already installed.
Improving Disc Brakes
Typically, all motorcycles from the 1970s and 1980s had brakes castrated by master cylinders with far too big bores and pistons. It was like lifting a heavy stone with too short a lever- pressure on the brake lever resulted in far too little pressure on the brake pads and only Arnold Schwarzenegger could get the disc front brake of a Commando to work. Add to it a wooden feel which allowed for no metering of the brake force.
Over the years many rectifications were tried with different calipers attached by unsightly and often off-line adaptors. The real cure, however, is to reduce the bore of the master cylinder and the diameter of the working piston.
Several re-sleeve kits are on the market but so are the reports of sleeves working loose and turning, thus blocking the holes for the brake fluid, resulting in no brake or, probably even worse, front brakes locking up.
We have, therefore, undertaken the manufacture of new master cylinders with smaller bore (13mm) for pre-850Mk3 Commandos
06.4871/13
and 850Mk3 Conmmandos
06.5742/13
.
For those who have the original master cylinder we have the "kits"
06.1939/13
for 750/850 models and
06.5741/13
for 850Mk3 models.
750/850 pre-Mk3: 06.4871/13
850Mk3 Rear: 06.5776/13
Rear Disc Brake (850Mk3)
For those who want a more powerful rear brake on their 850Mk3 we have a 13mm master cylinder, too, Part#
06.5776/13

And even more Braking for Sports/Race Use....
