How to Route Parking Cables to Wilwood Internal Parking Brake System using an E-Stopp

Most people have heard that the front brakes of a vehicle do a majority of the work and, as such, are most important. Thanks to key factors, such as gravity and weight transfer, it makes sense that the front brakes tend to take the most abuse. But it’s a little known fact that a close Second Place goes to the rear brakes (with the tree you’re heading for coming in a distant Third).
All jokes aside, if you’re on a tight budget you should still invest the money in a front disc brake conversion first. We did, which you can read all about it in the Apr. ’23 issue of Classic Truck Performance. Now it’s time to turn our attention to the rear of our ’64 Chevy C10 with a complete Wilwood disc brake conversion. We’ll also be pairing the modern rear discs with an equally modern electronically controlled parking brake setup from E-Stopp. Not only will these brakes do their part in supporting the front brakes but, sitting behind a set of 18- or 20-inch wheels, they’ll look the part, too.
After getting our original 12-bolt overhauled by J&S Gear (also in the Apr. ’23 issue of CTP) we reinstalled it with our existing Watts Link rear suspension. While we were at it, we bolted on a new pair of single-adjustable coilovers from Aldan American to match the set we installed up front.
As for the rear brakes, Wilwood offers a few different kits that fit the 12-bolt rearend in our C10. The one we opted for was their Forged Narrow Superlite 4R Big Brake Rear Parking Brake Kit. These forged four-piston calipers clamp down on 12.88-inch, two-piece rotors and will offer all the stopping power we need and then some. Another neat feature is the integrated rear parking brake assembly that hides inside the aluminum rotor hat.
To actuate the rear parking brake, we will be using an E-Stopp unit. The E-Stopp can be mounted in various locations on the chassis or cab and is controlled by a single button. It can even act as an anti-theft deterrent if the button is hidden in a discreet location.
Then, just to make sure we had no surprises, we called up Classic Performance Products (CPP) and ordered up a few more parking brake components. They carry several universal brake cable kits and á la carte pieces to complete any parking brake install. One of our favorites for E-Stopp specifically is their mounting bracket. It is an all-in-one solution for installing an E-Stopp unit where the mounting location lacks structural rigidity (i.e. the thin sheetmetal of a cab or inside the trunk of a car).
A final note before we get to the installation, we installed these parts on our bare chassis on a fancy lift at the In The Garage Media Tech Center. We’ll be the first to admit we are a bit spoiled, but you won’t hear us complaining. While having the bed off and the chassis on a lift does afford us easier access for working, it is far from a requirement to install these parts. A pair of jackstands and a floor jack will do just fine.
