NEVER put a torch to brake lines - whether there's brake fluid there or not. Brake lines are made from a product called bundy tubing, which is basically spiral-wrapped steel held together with braze material. If you heat this tubing, you'll run into a condition called "liquid metal embrittlement", which will lead to a dangerous situation. Even most metallurgists don't know this rare phenomenon.

Tom, most of the wrenching I do in my garage has to do with corrosion issues from the salt here. After living here my whole life, I got pretty good at replacing brake lines.

well
 

that info about the metal construction and the potential damage from heat is very good info to have.

thanks

thankyou for the warning


lots of PB and a wrench it is.

The tap did it, the lead-in thread was messed up. Although the tap itself ran me $20, which is a lot more than the 90 would of cost.

one side down (it looks SO clean now) one to go.




I'm changing the rear diff fluid also, anything else I sould do whaile I'm down their?
