Default Emergency Brake cable question

I was under my Dad’s 71 yesterday adjusting the emergency brake cable. Something must be wrong with the setup. I have the cable adjusted as tight as possible and it still isn’t engaging properly. It looks correct according to diagrams I have seen. However, there is a cable looping around the frame not connected to anything that has me confused. It looks like it is part of the setup but I don’t see it in any drawings. TRYING TO UPLOAD AN IMAGE BUT DANG! So awkward.

It looks like the cable is positioned much steeper than originally.

That "loop" in the pix is a driveshaft safety loop. Its to contain the driveshaft in the event of a U-Joint failure and keep the car from catapulting into the air. Instead, the cable will harness the spinning shaft and allow it to fling into the soft fiberglass near your ***. But, its the thought that counts.

The cable is part of the seat belt assembly as shown in the page from my 68 AIM.

So your emergency brake still not working? Is there any resistance at all when you pull the handle in the cockpit? If the cable is tight when you pull the handle about 14 notches, then something might be wrong with the brake shoes; maybe a cable came loose.

The extra cable is the seat belt restraining cable so they don't pull out of the floor is a crash.

we have all new brakes. The brakes work great. There is some resistance but not enough. Someone added a lug nut in front of the adjusting nut to give it even more tension so I know something is not right. Maybe the cable that goes between the brakes is stretched?

The foot brakes (hydraulic) and parking brakes (mechanical) are two separate systems.
Remove the wheel and with the rotor hole at about 6 o'clock insert a screwdriver and pull up on the handle until the rotor turns with a slight resistance. Adjust both sides.
You are trying to turn the STAR wheel with the screwdriver.


Next step is to adjust the cable.
Heres how:

Sounds like you need to adjust the parking brake shoes. There was a good post about adjusting the c5 parking brake shoes that relates well to the c3. You want the shoes tight so that you can just get the rotor on and off.

this might help understand. Read post 6. https://www.corvetteforum.com/forums...post1569707898

here is the c5 post I was talking about. Post 20 talks about it. I did my c3 like this and it works great. https://www.corvetteforum.com/forums...djustment.html
