Doing some "surf'n" and came across these being installed on an Audi A4

I never knew that they made a parking brake caliper...

Someone please have pricing and it better be cheap.

I drive around with a brick behind my seat sometimes, just in case I park somewhere that I am concerned with the trans not staying in gear.

I am seriously considering using these....

Wilwood Mechanical Caliper

A hot rod buddy said they use these when building custom e-brake set-ups for street rods.

A little (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) and (IMG:http://www.914world.com/bbs2/html/emoticons/beer3.gif) and you could probably design us a mount.

here is a simply way to make a parking brake. buy the willwood spot caliber at 57 bucks, then a push pull cable from mcmaster carr for 45 bucks. then just fab a plate that comes off of the diff cover to mount the caliber to. then a simple AL rotor made from 1/8 inch AL, double thickness at the caliber location. a few holes and a few screws ( 10 to 15 ) to hold the 2 layers together. the last thing would be longer roll pins and cv bolts ( 1/8 inch longer ) to sandwich the rotor between the cv and tranny out put flange.then just hook the cable to the stock brake handle.

now why put it on the tranny end, simple, why add 2 to 3 lbs of unsprung weight, and less trouble when working on the rear axles.

i bet this could be made in 3 hours for 150 bucks or less

now this would not hold up as an emergency brake but it would be a fine parking brake

Nice idea!! I bet it would work as an emergency brake as long as your emergency wasn't two broken axles (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) I guess the aluminum might clog the pads eventually, but a steel rotor wouldn't be much heavier and could be thinner.

That is a cool idea. You could probably even find an inexpensive disc to use from a motorcycle or go cart, then all you would need is some kind of mounting hat and caliper mount.

but the problem with a steel rotor is weight, and it would need to be .25 inch thick, because willwood makes several calibers but the thinest rotor they work with is .25 inch.

now yes AL might clog the pads if you tried to use it as an e-brake, but under nothing but a static load i dont think it would ever be a problem

0.085" aluminum "hat section" disk faced two sides with 0,085" mild steel.

i'm still not sure why we're not investigating using VW GTI/GLI rear calipers, but since i haven't done it either, i have no idea the mounting issues. they stopped the car and had good e-brake / parking brake performance.

Clay Perrine has already been working on a bracket kit for a spot caliper.

Our 87 Subaru GL-10 has it's parking brake in the front. The calipers are pretty decent size, and set up for a vented disc. Not aluminum calipers though.

Sorry boys, I have some dis-hearting numbers...

i've also been working on a bolt-on spot caliper kit, and durring my research the Brembro's came up around $700 each! The hot ticket would be a Willwood spot caliper, but i've been working on making a few myself.

Any thoughts as to whether it would be easier to make a bracket for the front or rear?

Next time I get under my car, I will look, see if it looks like it would be a complete pain in the ass.

Here is another company that makes mechanical calipers, but they look like an OEM supplier.

And could be drilled for lightness.........................

Hey iibdsiil,

Get rid of that rock and go to Sears, they have these for dirt cheap! They fit perfectly between the seat and side tunnel.

Why not take the whole front brake system from a motorcycle ,caliper, disc and mastercylinder and fab a lever to replace the hand lever that was on the handle bar????

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.....
