I've been toying with this idea for some time now & have finally decided to move forward.
We all know the parking break is a joke on theses cars & if you have a fairly powerful engine you can drive away with the break on & never even notice. In the sun with the top down & i don't even see the break lite.
So I decide to go design an automatic break  system. When the ingition is off the break is on & when you turn  the key it releases.  Another reason I decided to do this is the emergency break cable was way to close to my frt drive shaft ujoint after installing the TKO-600. If that cable got just a little sloopy ....well I don't want to even think about it.

I purchased a Linear Actutator  with a 2" throw which is on & off with each throw for $125.00 & it has a 200lb pull , so pulling the parking break cable is no problem.
Then I designed a simple circuit with 2 relays to operate the Actuator. I'll take more pictures as I do the install

THIS IS HOW TO HOOK UP THE RELAYS, I GET THESE FOR AROUND $1.00 EA.It can also be designed to operate with the engine on if necessary(with another switch), but I'm not interested it that. If my car is running & I'm not in it the wheels are choked...I don't trust the ER Breaks
...

This is the Linera Actuator & the 2 relays all wired
...


This is the interior without the parking break lever
...

I mountwed the actuator on a piece of 2" angle iron

...

Made it so it can move
...

This is a wire where the cable was closer than 1" to the ujoint
...




The assy mounted it's over 2" of clearance between the assy & the ujoint, in the pic it looks closer
...

Here's a side shot

...


Looks like I have to get stronger eye bolts..The actuator open this up like it was nothing, so it's plenty strong enough to alpply the parking break

...

Alan you never cease to amaze me.  You motorheads are WAY beyond me.  That's the only bad thing about this forum as far as I am concerned.  I USED to think that I was fairly intelligent but now I know how REALLY dumb I am.   Undecided I am proud to say that I know people like you.  Now I DO know a thing or two about airplanes but that does not do me very much good on as daily basis.  Keep up the good work you all are an inspiration to those of us that have to have someone else do most of the work on our hot rods.   Roll Eyes

Later

John you'd love it , I already took the parking break handle assy out ...much more room. After I get it installed be happy to build you one . The biggest cost is the actuator..everything else maybe $5.00

I was thinking of that but if one of the circuits failed or I lost power  I'd have a break lock down, this way I just have to adjust the cable. I don't think I'd want line lock on a driver.  Plus if I have to take it through inspection I will have a working hand break which they require in Delaware. It'll just be activated by a switch.

I'm thinking about it !st have to see how it works...I posted some more pics of the progress. Just need some stronge adjustable bolts & might have to move the assy further forward.  Anyoneelse would have to drill a hole in there frame & or rig some kind of mounting location. I designed & built my cutout for the TKO-600 & added a 1/4" steel plate to the frame for added support...But that's another story. Now you can buy these  in premade kit forms, this was not the case when I installed my TKO almost 5 yrs ago.

Here's the final install & it works great. Just have to wire it up now. I'll also install a hold back spring to keep tension on the assy when the break is off. Also coated the assy to keep water & dirt from getting into the unit. I will install a toilet stainless steel tube over the wire & go into the battery compartment & connect from there. Used grade 8 bolts also.

Alan looking good. Just a thought ....Maybe use some Heim joint. Looks like it would bolt up to the actuator ok but you may have to get a little creative at the cable location.

Also covered the wire with steel sheilding & will run it up above the transmission about where the radio is located to keep it away from the exhaust pipes.

Great job Alan. That actuator motor sounds really strong. Did you look and see if the quater panels buckled while pulling the cable? Just kidding....... Nice work.........jack
