Hi Michael,

Thirty-something years ago when the government started to require auto 
mechanic certification I tested for, and received, a Master's ticket. 
Around that time cars started to have disk brakes. Now they all do.

Disk brakes use a higher line pressure. Thus, when there is a little 
rust pitting on the brake lines the line *will* burst. Disk brake cars, 
such as the 1999 Accord, will burst brake lines at about 11 years old, 
while drum brake cars, such as a '50 Chevy might go 15 years without 
this problem. This is in climates where there is moisture and a little 
salt. In Phoenix, maybe a little longer than 11 and 15 years.

When a brake line bursts on a modern car two wheels will have no brakes. 
The other two will stop the car *eventually* perhaps avoiding a crash - 
perhaps not, but the car should not be driven until the brake line is fixed.

All of the brake lines on a new car will be the same age, and have the 
same degree of rust exposure. Therefore, when one goes, the others are 
suspect. If you don't replace all of them another one can burst at any time.

Inspecting them is no help. They can rust from the inside and look fine.

You *could* change them yourself. You would need a set of jack stands, a 
big rug or creeper, a special wrench for the size of brake line - looks 
like a six-point box end wrench with a segment cut out - and, of course, 
all the lines. But, you would have to know how to route them - they 
shouldn't be rubbing on anything for example - how to line up the 
threads so they will seal and you would need help bleeding the system.

I have seen first time brake mechanics spend days on the last step, only 
to get out on the road and have the master cylinder go out. $1700? The 
shop could lose money if everything that can go wrong on the job does.

Don't skip the jack stands. I have seen a good man die under a car when 
he was too busy to properly place the jack stands. We pulled him out and 
he seemed sort-of OK for a few minutes until he passed out. Then we took 
him to a hospital where he passed away.
