Reply to "What Are the Parking Brake Options with Aftermarket Brakes"

It’s interesting that the Tesla option has gotten this much discussion on “philosophy” rather than implementation.

I picked up a set of Tesla calipers, and am interested in them because of the weight reduction over the stock calipers (which I still use as a hand/parking brake) with my SACC Wilwood rear brake upgrade.

Pricing on the EPB (Tesla) controller is just high enough that I can’t justify the price to fix something that isn’t broke for something (weight reduction) that I’m not sure I would notice in most of my driving.

But someone’s gotta pay for the engineering & development costs…. I’m sure P-E did a study of development cost, vs. payback, vs. user base to determine their retail price.

I know I don’t have the skill to reverse engineer the Tesla controller (even though I have one, and the schematic).

But one day, if I’m feeling flush, I’ll probably pull the trigger on the controller, wiring harness kit, and mounting adapters…  Time will tell.

I am certain it will hold the car in place, and it will take about 2 pounds of unsparing weight off each rear wheel.

How are you taking weight off? The stock rear caliper stays and you are adding the Tesla. That's an increase in unsprung weight.

Why attempt to reverse engineer it. Jon has already done that.

I need to ask him if 1) it's true that the Tesla CPU applies the brake gradually 2) if he designed that into his adapter/controller.

I'll ask when the time comes.  I already have his irritation level in the high 90's.



Right at the moment, there is discussion about the right switch. His is three wires. My set up can only accommodate one wire.

His led also is two colors. Red for on. Green for off. I only need to know when it's on. What is this, NASA?
