Here is a pic of mine, note the front wheel studs are not installed in the picture yet.
The brake rotors I use are ultra light, I've seen them on ebay as cheap as $4-5 each. At the time, I bought the rotor, caliper, mounting bracket, steel braided line, and master cylinder with hardware for $24 a side. They are the best brakes I've ever had on my machine. I use a dual piston caliper with the bleeder screw in the middle so they can be used on the left and right side. The hubs are one piece billet aluminum and fairly light. I'm going to be making a few when I get back from Indy about the middle of December.

Are either of you using another extra bearing on the inside, or just the bearings in the hubs.

Just the hub bearings for now. Not a whole lot of weight on the rotor side.

Just the hub bearings, things would start to get pretty heavy if you had enough material there for a bearing. I've got a busy and hard season on mine with no trouble at all.

Glen what did you use for a proportioning valve. I had some from summit on  the Super Mod and they did nothing that I could tell.

On this one I used a Jegs adjustable and it seems to work.





When I first started the exhibition it would lock the front wheels up. I adjusted as we made laps and got them so the rears would lock and fronts barely on. Still have around 2 turns to go on the valve.

The one I have on my BP is a Speedway Motors and it also seems to work ok, but with the smaller EC brakes it is hard to tell if it is doing much. I think I run more front pressure on the small brakes.

Mine looked like the purple one and I could screw them ALL the either way and I could not tell that the did anything at all. May have to get the one from jegs to try it. I had the MCP brakes front and back on the Super Mod.

You have to use one master cylinder to make it work, with the bias bar you have to decide what end of the mower you won't have brakes on. With a dual set up as soon as one master is through its travel there isn't enough mechanical advantage there to operate the other master. So there isn't enough pressure there to restrict with the adjustable valve to begin with.
 I have so much line pressure with one master I can lock up my front wheels on pavement. I have them adjusted with the valve almost shutting the front brakes off completely and I can still lock them up on loose tracks that way. As a matter of fact, I have a valve inline that I can shut the front brakes off completely if I can't back them off enough, that has happenned on wet grass tracks until the track gets worked in a little.

That's the next thing to add on mine. These valves only take around 56% off of the end you are controlling. But, I do have a 10" on the rear so we will see this next race season. I still might put a shutoff valve on the fronts just in case.

Roughly the same thing. Only 57% reduction. I would love to find one that goes from 100% to 0 or 10%. Still looking.
