New Madass front brake kit (2015)

Up until the Mk 3 the disc caliper was mounted behind the LH fork leg and the bearing retaining ring had a RH thread. If you swap the calliper to the LH side forward of the leg there is a remote chance of the bearing ring unscrewing itself which is not good. The Mk3 got round this by superseding the lock ring with a circlip. I have seen a picture of a commando with a calliper on both sides of the fork, one in front and one behind the leg

Behind the right-hand fork leg.

Left-hand on Mk.3 (although the same fork sliders, disc and caliper were used).
 
"The kit is made for Pre MK3, If you fit this kit to a MK3 then I wont be held responsible for any problems you may encounter with fitment or its operation"
They are strong words from a supplier! I assume your explanation is the reason though.
Can you confirm Don? Not looking for a silly prolonged debate here, I'm just genuinely intrigued to know what the issue is. I would imagine others are too.

I'll explain again, my kit is made for pre MK3 if you want to fit the kit to a MK3 or any other motorcycle then it may not fit.
if you wish to purchase the kit and fit it to a MK3 as others have done and make the necessary mods then thats up to you.
Surely a seller cant be held responsible for problems encountered when a buyer attempts to use a product it is not intended for.

...........Mk3 has caliper on L/H fork leg on front side of leg. The earlier models have it on R/H leg behind the leg. Norton swapped it over by swapping the leg and just turning it around to save changes to production of parts. The bearing assembly of the hub was atlered as the L/H retaining nut would have been spinning the wrong way.......( fixed or replaced with the clip instead of a retaining nut )... I have a mk2a and my disc was on the left... does this mean that a mk2a is the same as a mk3 with regards to front brakes? .....

The switch gear is the main difference or hurdle to fitting this fantastic kit to a MK3 as worntorn describes in his application of it to his MK3. But since it is not a straight bolt on swap ( because of the electrical switchgear/throttle twist grip factory assembly change made on the newer MK3 ) Don had to put in the disclaimer.

Thanks CJ. That's all I was asking...!
 
Nigel, here is how I went about fitting Don's full single kit to my MK 3. Photos start on page 4.

I've got the full kit single disc version of this brake on my MK3 and I don't find it to be "Too much brake" at all. The lever action is quite progressive, that is is easy to regulate the amount of braking with the amount of squeeze. The brake is nowhere near as touchy as the double disc GSXR setup I have on my Special, but it also does not require near the effort that the original two-blocks-of- wood-rubbing brake did. Even though the old brake required a very hard squeeze for hard braking, I would never have changed it if not for the brake fade that occurred when used for hard repeated braking ( downhill switchbacks)

Mounting the Madass brake on the MK 3 was pretty easy, however there is a bit of fiddling involved in fitting the Mastercyclinder to the MK 3 throttle and switchgear. The Mastercylinder is designed to fit right on the pre MK3 switchgear, so it was expected that there would be some time spent making it work on the MK 3.

Glen, did you get the brake fade with the stock master cylinder or an upgraded one?

Three big squeezes in a row with the stock master cylinder did it.
The pads overheated and the braking effect went to almost zero.

I have a question for Madass:
Are you still selling the single disk kit with the slider. I have a '72 drum brake Commando and I want a better brake. Can't seem to find your stuff on ebay!
 
I assume it had to be a friction fade due to the pads losing their grip. Does anyone think differently?
 
Or fluid boil, resulting in further lever travel, if the lever remains hard then old style road going friction compound - easily remedied if so, boiling fluid is unlikely but not so easy to rectify if all else stays the same apart from pad material - more friction = more heat to disperse.
 
I'd like to make it clear that the previous 2 posts and others about brake fade have nothing to do with my brake kits or my original post.
 
Yep, no brake fade with the Madass kit, it cured that problem.

The problem was with the stock brake and the fading was not due to brake fluid boil or old pads. I had Vintage Brake Company's special compound for Commandos in there, but the pad area is just too small for hard repeated braking. Two successive hard stops it will do, as in 70 mph to 10 mph, accelerate hard to 70 then down to ten(switchbacks) Some fade will be felt on the second braking, do a third and there is no brake left.

These brake kits are not just a cosmetic upgrade, though they do look rather nice on there. Like you might get stopped before going off the cliff!

Hopefully this doesn't confuse things even more but....
If you have a mkIII with 1/2" sleeved master cylinder, could you use this brake with a hose available from madass?
 
refer to my post and pic I posted on Dec 29. if you wanted to use it like that with a different hose set up then i guess it would probably work but I have not actually used or fitted one to a MK3

polished calipers now available with this brake kit which is for the standard slider.
