Ideas for routing emergency brake cable to C4 rear eBrakes

I actually like the corvette ones better because they're cleaner looking. I'll post pics of both levers if I get a chance. I wonder why there are two different parts for them.

The simplest parking brake is, the one I used on my Camaro. Made by JAMAR. It's a hydraulic park lock. I plumbed it inline to the front brakes, so I can lock all 4 wheels in gear, plus does great burnouts. I have f/r brake pressure gauges, rear regulator, and a balance bar with wildwood reverse mount pedals, all under the dash. Anyway, you just apply like 4-500 pounds of brake pressure, and push in the knob to lock on brake pressure. To release, you just apply the same pressure to the pedal, and the spring loaded knob pops right out. Although not technically a parking brake, it actually works much better, as long as you have a good leak free brake system. And, like I said, all 4 wheels are locked in park. I think it cost only like $65. I think it was originally designed for fork trucks, etc.

Unfortunately, it's also a violation of federal vehicle safety laws....

(c) Vehicles not subject to FMVSS Nos. 105 and 121 on the date of manufacture.
(1) Each singly driven motor vehicle not subject to parking brake requirements of FMVSS Nos. 105 or 121 at the time of manufacturer, and every combination of motor vehicles must be equipped with a parking brake system adequate to hold the vehicle or combination on any grade on which it is operated, under any condition of loading in which it is found on a public road (free of ice and snow).
(2) The parking brake system shall, at all times, be capable of being applied by either the driver's muscular effort or by spring action. If other energy is used to apply the parking brake, there must be an accumulation of that energy isolated from any common source and used exclusively for the operation of the parking brake.
Exception: This paragraph shall not be applicable to air-applied, mechanically-held parking brake systems which meet the parking brake requirements of FMVSS No. 121 (S5.6).
(3) The parking brake system shall be held in the applied position by energy other than fluid pressure, air pressure, or electric energy. The parking brake system shall not be capable of being released unless adequate energy is available to immediately reapply the parking brake with the required effectiveness.

Legal, or not, it still works great for a "parking brake". Better than nothing, or in the case of a lot of older cars, and trucks on the road, they don't work anyway.
There are more, and more new cars, that are using a electrically operated parking brake, that can't stop the car either. If you lose brake hydraulic pressure, there are many parking brakes, that are going to "save the day" anyway.
The set-up I used, I can lock the front brakes hard enough to slide under power. The parking brake on my C5 is so bad at the moment, the car will roll on level ground. It helps not having inspections, of course.

I prefer to build a car that meets the requirements of the law, local or federal. Seems like a smart thing to do. That's why most of us are using the original C4 e-brake setup at the wheels.

If you notice, this thread is about how to route cables for a C4 rear e-brake, not to justify a jury-rigged illegal hydraulic park-brake system or an improperly adjusted or maintained e-brake that doesn't work.

Brakes being more important, where did you find DOT approved AN brake lines, and fittings?

Actually several companies sell them. I know for sure both Jegs and Wilwood have products that meet the DOT requirements for stainless brake lines.

The best e-brake/park brake setup is totally independent of the car's braking system and conforms to all legal vehicle safety requirements.

If you want to know where to get DOT brake lines and fittings, start a new thread and ask.

"on the date of manufacture"

I believe that was about 60 years ago.

The parking brake is on the bottom of my list of ways to make a Tri 5 even close, or better to anything resembling modern DOT safety standards. Even stock wheels are not even close, lacking a safety bead, and the list goes on. There is not much safety you can put into any older car, which is why I sadly gave up on my 1930 Ford.
