LeMons Barber MotorSports Enduro: Breaking the brakes

[H2OSB]

The Golf calipers are actually 38mm vs 36mm for the 944. That said, the Golf caliper/914 rotor set up makes for a very nice kit with replacement parts easy to find, and good pad upgrades available.

Though this won't do anything for you, a way to avoid all the work associated with turning down rear drums into hub is to use the hub portion of the type 3 two piece rear drum set up. Taking a very small amount of the diameter of the hubs allows them to sit inside a 914 rear rotor and they are dimensionally the same as the turned down T1 drum.

Lanner Khan is a good friend of mine so I'm using his bits and pieces for the 944 rear brake conversion, but he has the parts readily available to do either set up and his work is top notch so you can't go wrong. He helped out with my odd 944/914 hybrid front set up as well.

Above: A cheaper Wilwood clone, but needs much more master cylinder because of its larger (40mm) pistons.

We've done business with Lanner at VDubengineering) as well. He made the brackets for the front Wilwoods we use on the Blitzwagen. Excellent work.

We fixed the rear hub breakage problem, and can't tell you exactly what we did! We stopped repairs one-piece-at-a-time, got a new chromoly stub axle, new bearing and spacers, new axle nut, shimmed out any play, and on a new rotor hub torqued to over 300 ft lbs, it has held through two LeMons endurance races. We think there was some degree of play somewhere that with our very sticky Nitto tires, power shifts, and a high-torque 2.4 litre engine, was causing our breakages.

Oh man, I wish I'd known about those Type 3 hubs! I see that Mofoco sells them for about $30 each. I probably spent that much in carbide tool bits to machine mine. And you're right, H20SB, the Golf pistons are 38mm; I don't know how that other number found its way into my head.

The T3 hubs are forged steel vs cast iron of a turned down drum. The splines will last longer.

Does anyone offer blank or alternate wheel bolt pattern T3 hubs?

[H2OSB]

I seriously doubt it. You could redrill to 5x130 easy enough.

CB Performance has their race strength rear hubs in a variety of patterns and could be ordered blank.

Here is a pic of the hubs. It's a copy of the type 3 design.

Thanks Steve. Don't want to side-track FJs thread, but I have the CB hubs in a custom brake set-up. The glitch is I've got .005-0.010" hub runout at the wheel mounting face I haven't been able to trace down. I've checked the axles (944), the hubs themselves, even the axle/bearing spacers and everything is within "0" to a few tenths of a thousandth. The only thing I can identify is the CB hubs have a "hand-sliding" fit on the stubaxles (not as snug of a fit as a set of OEM drums for instance, which have to be lightly tapped on). I guess it's possible a few "tenths" non-parallelism in the HD IRS bearing spacer allows the hubs to mis-align slightly on the axles? Seems crazy to me. Just keeping my eye out for other hub alternatives (that can be modified to a 5 x 114.3 bolt pattern).

FWIW,
ISP West has the type 3 rear hubs in different bolt patterns.

Not sure if anyone is still following this, but ispwest only offers rear hubs in the 5x130 and 4x130, no blanks anymore. They are dual drilled for press in studs and screw in studs. Coolbrakes hubs are $362 a piece. Dont know much more than that about them, though said to be USA made...reason for high cost. Subarugears wants $400 for a set. But the rear brake "kit" they offer is $500.

For those using cbperformance hubs, how much do they cost?

Nice to know the type 3 hubs are forged steel and not cast iron. It was going to be these or 944 hubs for my setup (non racing like you guys) but havent found out what the 944 hubs are made of. Either hub will be redrilled for 5x4.5.

Does the t3 hub add any width?
