I bought my 426 over the winter and dont know all that much about it. It has some excel rims on it i guess, and one of the things i noticed is that the rear brake caliper doesnt fit well. Only about half of the pad is making contact with teh disc? Is this a common issue? What can i do to fix this ?

Measure the diameter of your disc for me.

It should be about 245mm, or 9 3/4". That doesn't look like a 426 rear rotor.

Looks the rotor is about 9", so i guess that explains why it doesnt go all the way up into the caliper?

The outside diameter of the hub looks to be about 4.75"

that hub/rotor looks like it can be for a different bike because those aren't even teh stock 426 spacers. at 9" thats only 228.6 (1"=25.4mm) and thats what it looks like. i would suggest if you don't want to get a new hub to fix the problem which could be expensive try to find out what hub that bike is for. because you might be able to get a bigger one (doubt it though).
im not too sure on how to fix it with out making different mounting brackets for the caliper or getting a new hub at the moment. that is a nice hub though :applause:

what is not the stock "yamaha space" ?

wonder if i could get another rotor that was bigger in diameter that would have more contact with pads? who knows what bike to order it for tho :applause:

See if the diameter of the shoulder on the hub that centers the rotor is the same as a YZ/YZF. If it is, then just using a YZF rotor will solve this. If not, a good guess would be a Honda, going by the numbers. If you could determine which model, you could then see if there is an oversized rotor available, or a later, larger one.

Nice looking hub but that's definitely not a stock Yamaha wheel spacer (the spacer between the hub and the brake caliper). I would just do like Gray says and measure the rotor mounting shoulder on the hub and make a phone call to a disc manufacturer like EBC or Galfer and see if they can get you set up correctly.

No i'm not sure, like i said i bought the bike as is and know nothing about the setup. I was suppose to get the stock rims with new tires too, but never got a hold of them.

The rear tire still locks up, but for some reason just doesnt feel like i have as much control on it

i remember a guy here tried to put a kx wheels on a yz and had the same result as you ,disk brake was to small

is there a serie # or something on the hub just to see if its really for a yz?

Call Galfer or EBC with the dimensions and bolt spacing of that rotor. They should be able to tell you what hub that is and whether or not they make a rotor that fits.

I agree.. How often are you on the rear brake to worry about it. Does it work when you need it? I like the hub, the disc is definitely from something other than a YZ. I don't use much more than that on my Galfer rear disc, check my garage.

It locks the rear up, so is that all i should really be concerned about?

I'm just such a perfectionist things like this bother me :applause:

I have a slightly used stock rear disk if you need it.
I will check to see what size it is - it came off of a 03 yzf 450 - I believe it is the same as a 426 but will verify
