anybody ever replaced burst steel brake lines with copper,and if so ever had any problems. it started with 1 i'm now at 3 every time i replace one another old one bursts

I don't know first hand, but was told by a mechanic I use for the trucks at work that he has seen copper brake lines expand to the extent that it seems like there is a leak. But, the fluid didn't leak out, just filled the expanded lines.

i use a mechanic for things like this where you have tobe under the car(i dont trust jackstands)so i use his lift,when i questioned him using copper,he said he's used copper for 50 years and would use nothing else.

WHOA! WHOA! WHOA!

 

Copper for brake lines?????? NO NO NO!!!!!! Never Ever do that!!!!!!!!

 

It may work for "normal" brake applications, but it won't stand-up to the pressures of a "panic-stop". You can generate over 2000# of line pressure in a panic-stop situation. Copper lines will not hold up to that.

 

Besides, copper lines won't hold up to the vibrations of the vehicle going down the road. It will eventually fatigue and break, leaving you with no brakes again.

 

Best to use steel lines, and just replace all of them, if you're having problems with them rusting. I know it's a pain, but it's safer that way. I've re-plumbed a few vehicles myself.

 

I work as a Machinery Maintenance/Repair Tech, I know a thing or two about hydraulic systems.

NAPA has lengths of seel line from 6 inches to 3 feet.

 

my turbo wagon had a replacement line, and the other one leaked. i fixed that, and then the fuel line leaked. but if you do the process of elimintation and fix it all, you wont have to wory about it till MANY years later

 

swing by jim's and i'll have a look. i can fix it for you for CHEAP. i'll be here at jims thru the week
