I wanted to ask this group what they thought about using compression
fittings to splice into a long brake line versus getting a flare tool
to prepare the connection for a flare fitting?
Is a compression fitting suitable for the task, and legal?
I'm sure that a flare fitting is more durable and avoids any issues
with rust on the outside of the lines. Where I would splice into looks
to be pretty clean, though. My mechanic said he would just use flare
fittings and splice it into the existing line, so that's what I plan
to do. I only need to determine how to splice the lines.

I would never use compression fittings for brake lines they are only made of brass and they're not designed for that kind of pressure that the brake system puts out

ReplyDeleteI agree , that is why they use the flare fittings.
ReplyDeleteflare fittings are used in many hydraulic applications, with high line pressures.
ReplyDeleteThe difference is....they are ...steel flare fittings and not brass.,,and normally don't come
in the small lines sizes for brake lines, but you can find them .
In actual use, the double flare is normally used in brake lines and there is a special flare
tool to make these line ends....but many times a single flare is used. . .
Steel lines and fittings are used for brakes as the pulsing pressure as you brake might
cause deformation over time with brass
That said, you can flexible brake lines from most any racing supply that are very easily
installed. These are steel flexible with telfon lining in many cases.
The question is.....for the little effort involved in making the lines as designed do you want
to risk a line failing when you need it ???
If a brake hose blew on my 1995 GMC K2500 Suburban it might just take out the steering as the truck does not have a vacuum booster. The brakes and the power steering are combined.
ReplyDeleteI'll either be getting a double flare tool or have the mechanic fix
ReplyDeleteit. I was leaning toward a sturdier connection but wondered about the
compression fitting.
Does anyone know if Mazdas use metric or if they use SAE
lines/fittings? I might end up buying a double flare tool combo kit
that covers both types but if they're too expensive I'll just get the
type I need for the Mazda brake lines. I'm going to replace both rear
sections since if one rusted through, the other probably isn't far
behind, and the other one looks almost as bad.

ReplyDeleteThey did that with the Oldsmobile diesel cars, too.
You are partially correct.... you have a hydraulic booster... powered by power steering fluid... if you blew a brake line you would still have brakes... if you blow a power steering line... you would have no steering and very hard brakes...(personal experience 97k2500 with hydroboost) except my hydraulic booster blew the main seal... but anyways loosing a brake line will not affect your steering in any way
ReplyDeleteGood call on that one.... autozone rents the flare tool you need
ReplyDeleteI have a quick related question. How often should you replace your brakes? I don't want to ignore that since I live and drive around quite a few steep hills.

Brakes are the most important element in a car. Without them, it is clearly very dangerous. Having a mechanic check your brakes about every two months will help you avoid any accidents related to the brakes. http://www.import-auto.com
