Ok, aside from the obvious answer of 'heat'... What caused this? It's only on the drivers rear line, the others look perfect. The lines have about 10k miles, and I got them from Luke at Lindsey Cadillac a few years ago.

Should a brake line ever get this hot?

Forgot to mention, zero track days or HPDE etc, pure street.

Only thing I can think of is the caliper seized and super heated the fluid...unless you just happened to drive over a small fire and sit there for a second.

Our traction/stability controls are brake controlled aren't they... I've been working the traction control sys pretty hard since the Procharger... I wonder if that is it?

The melting point of the plastic sheath must be much lower than the plastic covers on each end. Otherwise, they should be melted, too. Really, my theory isn't a good explanation. It's almost like a flammable liquid got on the brake line, but again, I would've expected it to burn the plastic covers on each end as well...

this was going to be my exact answer. I would pull the wheel, pull the pads, and examine them for uneven wear, check piston seals, and overall caliper condition.

I assume you know your strut is not attached at the top....

And while your in there, paint the back of your calipers.

How embarrassing.

I had to scroll back through the pictures to see what 54 was talking about regarding the strut. No bueno.

The bolt came out of the strut retainer...

I'd replace that line sooner rather than later and see what caused it... Kind of a safety issue

LOL, good eye. I'm modifying the MM lowering spacers to raise it back up about 1/4"... That is how I found the brake line problem.

And my V is a lady... Nobody but me gets to see the back side of her calipers. Except I guess in this case where I posted embarrassing pictures of her online... which I guess makes me a bit of an ***...

Any chance we can see the other line, side, for comparison?

The other side looks fine. It seems to be just the drivers rear. I will pull the caliper and check it out.

You sure that's heat, and not chemical damage ?

Looks like heat to me. The thing about braided steel lines is they will transfer heat unlike stock rubber lines. Now that there is a steel braided line crimped to the metal that is attached to the caliper, any heat generated by the caliper will travel down this line as well. It's not just the fluid getting hot, the whole line is getting hot because it is now mechanically attached to the caliper.

I would take it for a 5-10 minute drive with minimal brake usage and check that wheel against the others. My bet is it will be considerably hotter than the other 3. If so, looks like you will need a caliper rebuild.

I see your point, but I would think if the caliper is locked up there should be obvious evidence on the rotor or pad wear. The more that I think about that potential cause, I would think there should be other red flags screaming just as loud as a torched brake line.

I had significant brake overheating issues on my last track car. The front calipers were cooking fluid, piston seals, wheel bearings, wheel center caps, and chewing through track pads in a single day. With all of that repeated and well documented abuse, I never once saw any damage to the goodridge braided lines on that car, not even discoloration on the coating.

I'm now leaning towards the theory that he ran over a small hibachi at his Memorial Day cookout at the park. I would check for signs of BBQ sauce on the lower control arm...

Hey man, I kinda noticed in your picture that the driver's side, it looks like the line is hitting the shock body. Now, admittedly I have never gone on a drive and touched the shocks on the V... But shocks on my dirtbikes that I used to race would get hot enough to cook an egg. That might be some of your problem. It looks like the top few pictures, the line was rubbing on the shock body enough to leave scrape marks.

Edit: also, on the passenger side, I know that its probably a picture angle mind trick, but it looks like your line is very close to the wheel. I have personally had a wheel shave right through a brake line before. I very narrowly avoided an accident. It looks like your brake lines are almost too long to me really... again that could be camera angle screwing with my mind

Did somebody try and sabotage your car maybe?? Lines should be able to handle the heat coming from our brake system without any issue. The hottest part of the line will be the part coming out of the caliper.

The coating could be defective and just chemically broke down. This coating also doesn't serve any purpose other than corrosion resistance to the actual line itself.

The shocks won't get hot enough on these cars unless you are offroading them, and at that point they will leak fluid everywhere.
