      When I talked with MCP on the phone when I started building a new F-125 laydown kart, before I got my superkart, they readily admitted that the speed and weight of a laydown 125 shifter kart was pushing the capbility of what they had available.  I did buy the biggest stuff they had, but never finished the kart so can’t say how the brakes worked.  MCP did suggest that I consider brakes from a shifter kart or superkart.  Off the top of my head for superkarts you are looking at PVP, Kelgate, Brembo and possibly others.  If you go that route, I would recommend buying the complete system front and rear along with the master cylinders.

      Have a look at Wilwood’s offering as well.

      I’m sure Brian Wilhelm will chime in, but I believe he runs MCP/Enginetics equipment on his kart.  I’m building a 150cc clutch kart to run Unlimited and possibly F-125 if I can carry enough methanol, and I’m using MCP/Enginetics on mine and have been getting some help from Brian.  Some of it is the same equipment I used on my TaG-Enduro kart I built in 2008.  That kart was fast and heavy (anything with me in the seat is heavy) and it stopped fine.

      I just bought a nice 7-1/8″ vented rotor from Brian (made by Terry Ives) that bolts to standard MCP 4-bolt brake hub for 1-1/4″ axles.  I’m using an MCP billet rear caliper that has 1-1/2″ pistons (don’t think they make this one any more).   On the front I’m using Enginetics EC-750 single piston caliper.  This is the large caliper that has a 1-3/8″ piston and uses the “scalloped” Enginetics pads which are still available.  I just looked and Russell Karting has a set “in stock”.  That’s were I got mine back in 2008.

      Jeremy, did you really mean “aluminum spindle” in your post?  Or did you mean an MCP style aluminum hub and brake carrier?  I assume you mean the latter like shown the picture below.  Brian also has 1/4″ thick cast iron discs for these hubs as well.  I intend to get a pair of those.

      Bruce you are correct I meant the MCP aluminum hub and I already have the slotted 1/4″ cast disc on it. I use the same rear caliper as you posted but I was mistaken I have the black MCP master cylinders with the larger reservoirs. The system can be great and I can stop super fast but they no longer make the front pads so time for at least new front calipers. Plus the system has always had the problem were I have to pump the brakes which is no good.

      I have looked at those front calipers and I know they work for Brian who is going even faster than me. But I have also heard they need a lot of adjustment all the time. Like you said Brian will probably chime after he gets home from Grattan.

      I have talked to a couple of vendors now too and along with Greg’s recommendation they are saying look into the wilwood. So I will at least explore those as well. Since there isn’t much room up front for big calipers on a laydown most of the superkart options don’t work. Hopefully I can get it all sorted before Mid Ohio.

      Talk to Craig Dori in Indy about Wilwood.  A few years ago Craig designed and made a new laydown frame and did a lot of work with brakes including some components from Wilwood.  I think he had issues and ended up using something different for front calipers (this was a 100cc kart though).  I can get you Craig’s contact info if he doesn’t comment in here.

      You’re right about the EC-750 front calipers.  They are not self adjusting so as pads wear you have to manually adjust by adding/subtracting shims.

      FYI – Craig also had new front brake hub/disc carrier set ups made and has some on the shelf.  I bought a couple of sets recently, but he has more if anyone needs some.  I think he has discs for these but they have the standard MCP bolt pattern so you can bolt on the discs you already have.

      Those look nice. I don’t now if those would be a bit stronger than the 6 spoke MCP versions or not. One of our concerns is that I must be getting some flex or different metal expansion in the front carrier system to be having the pads knock back. I think what we are going to try and do is convert the discs to have a slight float like many of the sprints have. That should help have a more consistent knock back so at least the pedal feels the same every time.

      If you have Craig’s contact please send it. I used to have it and have talked to him before but don’t know where it is now. He used to have a website, is that still working?

      Craig’s website is no longer active.  Craig sold off much of what he had put together and has moved on I think.   Jeremy, see your PM.  Contact info is there.
