Very nice work. (IMG:style_emoticons/default/beerchug.gif)

Wilhelm,

Just catching up after 5 days in Puerto Vallarta, Mexico, thus the late post.

Nice work. Good to see someone thinking outside-the-box. I curious why you chose the 928 bearing? Most think the 914 bearing is more than adequate, and the 911 bearing beyond most needs.

I went with the 911 bearing mostly because it matched the late 911 axles, and I also moved the bearing further outboard in order to fit my 6 speed transaxle. Much like your work, here are a couple of photos of what I did (BTW, I can appreciate the amount of work that goes into this kind of thing). I fabricated a custom trailing arm.

Junk the Wilwood spot caliper. If you set the brake when the rotor is hot, after it cools it won't release. You will end up beating the shit out of the caliper trying to get the park brake off.

Hi Clay,

I just ordered a set of Wilwood Mechanical spot calipers to make parking brakes for my V8 car that will have Boxster brakes with Rich Johnston adapters. Just to be sure I called Marty today at MSDS that runs them on his Turbo 914-6 car and they did a second car and he says they are perfect. I went over this with Eric Shea for a long time on the phone and he said as far as this thread went, it made no sense as the 914 brakes are really set up to be mechanical E calipers when we pull the handle.

Is this a red-hot racecar brake problem? Can it be the pads?

The only discontinued item on the web was a different number that the 120-2281,
120-2280.

Talk to Rich Johnson, and have him tell you about Mike Floyd's car. It was the one with the stuck park brake that got beat with a hammer to make it release.

Clay,

This was Rich’s answer to my email on the question. I guess we will need to see how Andy’s set up is going to work as it is done and Marty’s 2 set ups are working perfect for 2 years. I am a $100 in parts now so I can change out and sell what I have but I am looking for the easiest way for an E brake. I have seen Eric’s tread on the 911 set up but I do not know where to get the parts and how easy it would be to set it up.



“The problem Mike had was with the spot brake from Wilwood. It would hang when set for a period of time and Mike eventually went to the 911 based drum brake setup. I wouldn't base all systems on this one case Bob. I'm not sure the execution of Mike's system didn't contribute to this hanging issue. I will say that the drum system has been a much better setup and very OE looking vs. the mechanical look the levered spot brake had.

Wilhelm I have been anxiously waiting to see the rest of your solution ie the spacers inbetween the cv's and stub. I have some 18x11 turbo wheels waiting. I may, to save the machine work just use the 914 bearing and hub and just move it out but the spacer will be interesting. I think it will need to be mild steel to have 6 threaded holes for the cv and 6 more counterbored for the stub flange. Might as well make it the length you need to use the axles you have. I haven't looked close but it looks like the inside of the new wide wheel is just about where the stock wheel is. I hope the wheel wells are not any closer than the control arm.
Looks great sofar.

I'm anxiously awaiting the solution too! It has been miserably cold here and in fact is snowing again. The "shop" (barn) is unheated, work has been soul sucking, the children needy, the wife has the projects list (whine, whine, whine)...... I have the engine and tranny in, one of the half shafts is sitting in the hub and I was planning on tomorrow going out and running the suspension through its full range to see if I will need a spacer versus just purchasing longer axles from Sway-a-way. The deciding factor will be if the axle has enough room when the suspension is in full extension. Then it comes down to money and time. Probably cost me $100 in material and my time to make the spacers versus $300 to just purchase a pair of longer axles Swayaway Axles. God and my wife willing I will make a decision tomorrow!!!!!!!!!!!

Oh yeah I forget about the weather everywhere but here. It was 37 with 30 mph winds sat and I tried to find a doe I liked but the only good ones were by the gate as I drove out and my rifle was in it's case unloaded in the back seat of my sub. It's 30 this morn. and no wind, perfect except that sun is my wifes only day off and we go to ihop and my son just got back from san fran. and we will eat with him and his girlfriend and visit.

Do 914 guys ever use shorter shocks to limit droop? I don't know how much motion you need but it doesn't seem like more than 4 inches at the wheel, I don't know these little cars that well. Also would it not be cheaper to just open the inside of the control arm up the required amount? I would like to run my axles angled to the front some and that will agrivate the problem even more. That also means I will need swayaways probably. Unless I find the longest 911/944's I can get and just go with that. I still need to study up on computing the proper axle length to fit in the cv's to keep them centered for whatever I decide on. It seems the 944 may be the longest stock one available. Course I guess I could shop for some used custom ones.

I use a motor oil and juniper wood stove in my shop some but I also have my old 3 ton house electric heater but it really runs the bill up. We are just now getting into our cold season.

My wifes been patiently waiting on me to redo the kitchen cabinets for 6 months.
