Sierra hand brake cable and exhaust. Is this a problem?
bumpy - 9/5/15 at 02:04 PM

Hi

I have a Sierra based car which has the standard handbrake cable set up. The cable seems to have a metal flexible outer cover.

I have decided to re-route my exhaust system out of the back of the car. It currently exits under my drivers door and the drone can be pretty annoying.

The only way to get past the 'swinging arms' is to bring the exhaust to the centre of the car alongside the diff. All this looks OK except it also gets very close to the handbrake cable.

My question: " Is it OK for the handbrake cable to get hot or does it have some form of 'nylon' lining that can be damaged"

It will cause issues, you could fabricate a heat shield, that may help

Thanks
I can clip it probably about 1-2 cm away from the exhaust pipe. What would you suggest as a heat shield, perhaps a metal sheet between the two or wrap the hand brake cable in an 'asbestos' type insulation?

You could also use exhaust heat wrap as protection.

Nice idea.

The more I look at the set up (which I didn't do!) it looks like the cable should be routed through that hole with a rubber grommet in it. Is that the case?

Heat wrap, good idea.
As for heat shield use ally sheet with heat mat on the hot side.
There are reflective heat mat tubes sold by CBS that will wrap the handbrake cable

Use what fits, use different solutions together.
You are combating convected & radiated heat

Thanks Snapper, useful info, but if the cable should be through that hole it will be well clear of the exhaust.
