Handbrake problem after new headers/exhaust installed.....

If you haven't had the headers and or exhaust coated or covered with heat proof matting then yes most definitely has melted something.

As stated above, that is normal (and expensive). Always best to coat and wrap headers given the close proximity to the handbrake cables.

 

Had the same thing in my first CS with AP headers. Burnt the handbrake cable, had to have it replaced. Removed AP headers and went back to stock.

 

So we’re mine. I believe the brake lines runs along the frame rail in very close proximity to the headers resulting in the cable melting.

 

I believe some use a heat wrap tubing for fuel lines to insulate the hand brake line because of the close proximity to the headers

 

Header blankets seem to fix this issue, probably the best option.

 

Thats unfortunate. I also recently ordered a set of AP headers with ceramic coating for my 05 F430 (not yet installed). Apparently this is fairly common from what I've read, depending where your brake lines run. There's some old threads on the heat issues and different solutions. I am leaning towards the Capristo blankets solution to hopefully avoid this. Expensive, but you I guess you gotta pay either way.

 

Yes

About $1200

Insulate the cable after you change it

 

My headers and high flow cats were ceramic coated and then wrapped with header wrap material. No problems after ~500 miles of very spirited driving in Alabama summer heat.

 

The ceramic coating might drop the surface temperature but would you grab hold of the manifold pipes with the engine running, that’s why the blanket insulation is lots better

 

Ceramic coating may lower the surface temp a little but what it really does is increase the thermal resistance. That means heat moves from inside the pipe to outside the pipe more slowly, like turning down the faucet or insulation in your house. The exhaust gas stays hotter and as a result, more heat goes out the tailpipe with less into the engine bay. NOTE: none of that means that the pipe is cool. Adding blankets further reduces the thermal transfer.

 

that's labor + parts?

 

The blankets make a big difference to my engine bay, I understand the thermal coating only knocks 40c off the surface temp so it’s not doing much

 

....if only blankets didn't cost an arm and a leg

 

yup...it's a hard pill to swallow but It's the best option and you'll be glad you did it. The heat in the engine bay is dramatically lower.

 

A cheaper option to the blanket is to wrap the whole exhaust using this titanium wrap

I've used it previously on one of my cars. Turbo Toyota Supra. Wrap the manifold. Turbo and down pipe. Made a massive difference. Made the down pipe touchable after driving.

It’s on the other side of the frame rail. Probably didn’t melt. My mechanic said if the headers cause an issue he will replace the line for free.. that’s how sure he was that it wouldn’t do anything to the cable.

 

Hello from Athens Greece i have capristo headers and i had changed three sets of handbrake cambles ,no wrapping ,no blankets if you don t want to destroy the headers The only solution is ceramic coating But i did something else A small shop makes for my f430 new cambles without teflon inside (better at high temperatures not smelting) and not informal Also the cambles have bigger cross section trust me it s the only solution before the ceramic coating Good luck sorry for my english

 

Thank you for your post and your english was just fine!

I’m considering a set of inconel headers and catted pipes on my CS. Will try and find someone in the US that sells a more robust cable.

 

I've had ceramic coated AP headers on my 430 spider for 2 1/2 years. I've driven for hours in 95 degree weather and tracked the car hard in 85 degree weather. Drove from Chicago to Naples last fall non stop (except for gas) probably averaging over 90 mph. No issues with the hand brake.

It's not just the cables - everything plastic or rubber in the engine bay is going to have a dramatically shortened life if regularly exposed to the elevated temperature; think wiring looms, fuel vapour components, RTV sealant, gaskets, o rings, etc. etc. There's also increased danger of combustion if there's an oil or fuel leak.

To my mind it is crazy addressing a symptom rather than the root cause on a car such as this.
