The parking brake cable is touching my exhaust pipes and rattles at rpms around idle. This didn't happen before I had the pipes redone. Think the cable was tighter up against the previous exhaust pipes. So, I'm looking for a solution. The pipes probably get too hot for a rubber hose over the cable. Insulation around the pipes would wear thru in a short time. Hope I don't have to fab something elaborate. Is there a material that would be soft enough to dampen the vibration, tough enough to tolerate the cable rubbing on it, and heat resistant enough to tolerate the exhaust pipe. Surely others have had this issue. Solutions?
http://www.adlinsulflex.com/heat-resistant-tapes/pyrosil-tape They make some others, but that's what I would use for your situation.
Real " simple ", get a spring that will hold the cable away from the pipe! It doesn't need to be much and you can still use the e - brake. Even though it may still touch the pipe when the e - brake is on ( won't hurt a thing ), you won't have rattles when you're driving!
Or you could listen to Simple man as I have no mechanical skills what so ever. *Is a member of duck-tape fix's the universe Club* I know my fix would work..but a spring sounds like a real fix not a cheap quick fix
I like the spring Idea. Or put a bottle jack with a 2x4 under the pipe and move it out of the way a little.
Sent a query in to ask if they thought that was a good application for Pyrosil tape. Never heard of a high temp rubber tape before. Wasn't thinking about a spring because the cable is UNDER the pipes so there's no place to attach a spring to pull the cable down away from the pipes. Gave me another thought though -- how about a spring to pull the cable snug against the pipes? Wasn't a problem with the previous pipes when when the cable was snug against the pipes. I just put a drive shaft loop in that happens to be right above the cable. Put a light carb return spring between the loop and the cable to snug it against the pipes. Started it up and no rattle yet. I'll have to see how it acts with different loads (in gear, alt driving elect fan, AC compressor running). Thanks for the ideas -- I was drawing a blank.
I guarantee its a its a valid use of Pyrosil tape. We used it on high heat machine components at work all the time. But yeah, seems there are as many fix's as there are guys thinking about the problem. I haven't got my new exhaust system in yet... Thursday... so if this problem happens with mine, I am using the Pyrosil tape as I like fast, easy fix's on non critical or visual components. Besides I am biased, as it was my idea
You have a good idea, but the specs for the tape say 475°. The exhaust gets a lot hotter, I think? We'll have to have someone with a pyrometer to check it out!
You could very well be right.. I have a hard time imagining a exhaust pipe getting hotter than the specs...but I never checked.. So might save some frustration of cleaning burned rubber tape by checking first I am sure we are all missing the easiest solution like a bracket clamp or sumin... lol
