Brembo cable actuated parking brake.., hmmm...wonder what these cost?? :) Options

[scotty914]

aaron, your drawing is basicly what i thought of when i made the 4 post on this thread. i would not put it on the bottom of the rotor, due to water, grease etc dripping and collecting there. not grease would not let them work any but better be safe. and as a parking brake i doubt we would ever have to change the pads in the life of the car.

Hey guys and gals, I'll be finishing off the Wilwood e-brake set for the 914 this month.
I've actually been waiting for some news to break here on the 914 board --and just buy the kit--but impatient as ever I've built (2) sets for two cars / myself and a good cust'r. The kits operate on brackets that mount to the trailing arm (bolt-on), and allow the wilwood to float (required design). OE cables go thru new support brkts and we are using 986 rears (on Rich Johnson adapters ) (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) with 911 vented rotors. The unit sits accross from the main brake caliper, like the new Carrera GT. (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif)
Unfortunately , these will be working prototypes--not a sale item until we do some tool and die work for alum castings...as these are made from C/R steel and carry lots of unneccessary weight . No jpegs...but the 2 cars should be at Willow Springs @ WCC '05. I could'nt make these from steel @$150.00 a set> too much fab work, however casting out of alum. will bring the price into reality.
BTW, the Brembo setup was dominant on just about every Euro exotic at the L. A. Autoshow last month. Kinda funny how each mfg. mounts their ebrake at a different position !

Maltese, you wouldn't happen to have a drawing of your 935 fan setup would you?

[Maltese Falcon]

Don, I've adapted the horizontal fan "As is" from the OE 935 set up (aka 911/78 at the factory). The only required fab work were: bulkhead clearence for the outboard alternator; alt.support brkt ; 4 way oil feed line for (2) turbos, fan drive and OP switch; and an engine oil cooler shroud. I did all of the work w/o any factory diagrams > I'm sure they're avail, here's a teaser , I'll try to post a jpeg here (IMG:http://www.914world.com/bbs2/html/emoticons/boldblue.gif)

do you have any sound files of that motor? (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Here's the scoop on my parkbrake setup.

About 2 years ago, I built a prototype setup for a parkbrake that uses the Wilwood spot caliper. I even went as far as putting it on my wife's 914 for testing. It works fine. You can see picts of the prototype Here.

I took the prototype to a swap meet a Zim's locally. I wanted to see what kind of response I would get if I decided to build it.

I got 2 people who were interested.


The prototype parts went into the parts pile in my garage.

I am building a 944 turbo caliper mount for my car. I am building one other set for a friend.

IT will use a Wilwood spot caliper for the park brake. The wilwood caliper can be bought with spacers to use any sized rotor.


As for the inboard park brake. It could be done real easy. Just buy a rotor, and weld it to the output flange on the trans. make a bracket, and install the caliper. ONe caliper would be fine for a park brake.

Here's a picture of the protorype 944 turbo caliper mount with park brake for a 914. The finished ones are being done by a machinist on cnc mills.

Marty,
As long as were off topic, I am considering an intercooler for my setup, could you post pictures of yours and how you managed the trunk lid.

The problem with the Wilwood Spot calipers is that they are only for a .38" width rotor, so if you want to use it outboard on vented rotors, you'll have to open it up and make custom spacers....adding to the cost of the conversion.....

I think you are looking at the hydraulic spot caliper.

The mechanical Wilwood spot caliper will is available for 0.81" (20.6mm) thick rotor - #120-2280 (right) and 120-2281 (left).

[iamchappy]

Ive been considering the e brake for some time now. Since I also have the turbo brakes your install should make mine that much simpler.

[joea9146]

Looks great.... Did you Fabricate the Bracket ?
Is the Spot Caliper Mechanical ?

[Maltese Falcon]

Clay, you're right on the money with needing only one spot caliper to stop the car...on my 930 turbo a small 1/8"section of the ebrake spring broke off inside the drum and you could NOT even push the car (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)
Sound byte of the horiz fan will eventually be on the msdsinc. site> working on it.
It does idle with about 80 Db of evilness (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif)
Chap, since we're so off topic, PM me and I'll give you some good pointers on the IC set-up. If you want to go thru (cut) the trunk lid, start with a donor trunk !

That is the parkbrake setup that I took to the swap meet. It was to be a bolt on, but no intrerest.

I can resurrect the project if I get some interest. I still have the CNC file to make it.


So how many of you would be interested?

If you are talking about the Bracket in the Picture posted by 94Teener I would be Interested in a Kit to do one Wheel

I would be interested in it Clay, I like Aarons idea also but I started thinking if it was pulled inadvertently while driving, it could and probably would rip the side out of the tranny. It was never meant for outward pressure like that. It might work for a 4 cylinder car but the weight of the V8 may kill it. I could be wrong though. But what if I am not.

[BigD9146gt]

Clay.... DAMN!!! That steel contraption! (IMG:http://www.914world.com/bbs2/html/emoticons/chairfall.gif) Talk about sprung weight!!!!

But i like the idea. I have something along the same lines but just for the spot caliper.

Maltese, I spoke with you a few years back at the GAF... you had just completed that motor, i remember most of the details.

Do you know where to find a drawing of that fan setup?

[andys]

Clay,

Any pic's of how the stock cable attaches or is adapted to the Wilwood spot caliper? I'm not clear on how the lever position works with the position of the cable.

Andy

[ClayPerrine]

The caliper in the picture is on the wrong side of the car. The lever actually comes out the other side.

Then I made a rod to go from the cable to the caliper arm, and a spring to pull it to the released position.


Sorry... never took a picture of that.

[iiibdsiil]

What brake setup will be required on the rear to utilize that Clay? Not all of us have the same rear brakes due to upgrades and what not.

I am not even sure which brakes I have, but if the price is right, I am down, if it will work. All I would need would be the bracket, I can outsource the rest of the stuff, if that is okay.
