New E-Brake idea as seen on Tesla

[bikersmurf]

Saw this setup on a Tesla.

A little research has shown their setup uses Brembo components. Photo and info courtesy of: A detailed and revealing photo tour of Tesla's Brembo brake calipers

Now since I have a one piece case, I don't need this solution (Yet). I don't have the time to develop the idea, so I thought I'd put it out there. I'm sure there are other calipers out there that could be the second caliper, however as much as I prefer to KISS, electric would be easy to find a place for the switch... have a switch/button and there could be many options. Taken a step (or three) further, one could have an electric caliper on each corner and be able to have a brake on each corner... allowing for traction to be transferred to the wheels with traction and stop the spinning wheel from spinning with open differentials.

It's an idea I've been developing since before I saw Tesla E-Brakes, but now I'm seeing it used on a production vehicle. Now if someone runs with this... I'd be happy to do a long term test on a prototype.

I'm also happy to toss around ideas and help perfect this general concept. Potentially it could turn open differentials into pseudo lockers (or at least so a skilled driver could go much further). Skid steering also can help at times.

I'm not even sure if those calipers would fit over my Chevy full size rotors I have on on the rear axle (Given they're about 1.25" thick). The front Landcruiser rotors are about .75" and would be an easier fit over the rotor.

Also mechanical/hydraulic is available...

I'd like to see a catalog on brake caliper options.

I like where you are going with this.

I'm throwing the idea out there for someone else to run with. Waiting for me to go anywhere with it would be a bad idea. It would be way down the list if it even made the list. As much as I'd like to have it, replacing my E-Brake shoes makes far more sense in my case.

Quite interesting. Not to say I can do anything about it, but I like the idea a lot. That seems like an easy way to add parking brake. However, it's unclear how is the second caliper mounted to the vehicle.

I just purchased a Tesla, and was checking out that same forum. However, I know almost nothing about the vehicle mechanically. It couldn't be any more different than a Cruiser, but the one attribute that drew me to it is that it's such an amazing build. Every cool idea one can possibly think of is built into the vehicle. The same is true for many of the incredible builds we come across in this forum, just expressed in different ways.

The range Rover evoque has a fairly small caliper with electric parking brake as well as the Jeep renegade I believe. I think you would just need a momentary switch to engage or disengage. I think you could plug office hydraulic port.

If I remember correctly, they require a CAN signal to engage.

My solution is Mustang calipers with 4Runner rotors. Not electric- but at least my rear calipers aren't bigger than my fronts!

There are many cars here in EU with E handbrakes, including older models. I had a temporary car 10 years ago with one. Not sure but it might have been a Renault.
These have smaller calipers, don't know if they used separate calipers, a dual caliper or if they pulled the cable electrically. Might be interesting to look into as it would provide a cheaper solution.

Using the brakes as limited slip diff replacement was already done on some Landrovers.
It is not that difficult when ABS is installed, just add some software. Adding ABS to a 40 ............

As for how they mount, it looks like two bolts into a mount and the calipers float on the 4 'pins'.

The key idea I was throwing out was a second caliper for an E-Brake. The downside to disc E-Brakes is the disc is too small and exposed. By adding the caliper to rear wheel discs the rotor is larger and out of harms way.

Now the Brembo caliper is interesting, but I'd like to pick the collective minds here to help find a solution to a problem so many have. I'd love to have a rock solid E-Brake that holds 100%. Traction aide... that could be a possible bonus. It could also be one heck of an anti theft device.

If I was to consider electronic E-Brake, I'd want to do so without a fancy computer. It would have to be stupid simple. Perhaps a couple spring loaded toggle switches to engage and a single to set them. Throw in an indicator LED which shows when they're on while the ignition is on.

All I see their is 4 pins. 2 for engagement and 2 for disengagement I'm guessing.

I'm thinking same problem as trying to use some of the Ford calipers- - -anything that protrudes inward will hit the frame when you bottom out the suspension- - -lemme know if I'm wrong.
