So, replace them! No big deal....less than $40 for both front lines. What do you expect from writing to Ford concerning your 12+yr old vehicle? Dave S(Texas) Metal brakelines are not supposed to rust out. They are supposed to be formed from stainless steel or marine brass and should last as long as the engine. The rubber connector hose is a different story and oddly enough they looked fine. |
I think your name should be OVERLY OPTIMISTIC
considering your insane idea that Ford may want to pay
for repairs to a 12 year old truck.
Hopeful just doesn't do it.
PS I have never seen stainless or marine brass used in
auto brake lines.

(which it would be), but I'd be willing to take a chance on it.

want it to last to long anyway and brass is too soft for this. A
simlpe trick that I have used that works well is to spray the brake
lines with gear oil in a old paint spray gun every fall and spring. I
do not have "normal" failure of any metal brake lines. My 89 burbs
lines still look almost like new. Another thing, rust is a galvanitc
reaction of sorts with atmosphere and metal and when you rust proof
the car, anything that is not rust proofed tends to be atacked worse
because a difference of charge or potenail develops between car and
air aggravatted by salt and rust proofing focuses the "discharge" of
the potentail and the rust process that results to unprotected areas.
Back in the 50 they used to put anode lead bars on some cars to
control this process scientifically and that would sacrifice
themselves while saving vehicle. You will not see that today because
all that lead would not be environmental freindly. Also, brake fluid
is glycol based and atracts moisutre so it can be attacked from both
sides of pipe wall sometimes.

Stainless costs too much for penny pinching detriot and they do not want it to last to long anyway and brass is too soft for this. |
for about the same as for the bundyweld tubing. Stainless has a bad habit of
developing stress/corrosion cracks which is a very bad thing in a brake
line.

attached they would have been zinc. Lead bars would have increased the rate
of corrosion. (see
