A brake line that's below the master cylinder that looks like a spring. Anyone know this? I can't find the part anywhere and I believe I have a leak from it.

 

That turn of 2-3 coils of hardline brake line is to absorb vibrations between the master cylinder mounted to the body and the T-union bolted to the frame. To replace it just buy standard line and coil it around a pop can to recreate the twist.

If you have a standard shift there is a similar coil along the passenger side for the clutch line.

 

Any idea what the flared wrench size is for the brake line nuts?

 

Totally going from shoddy memory but 8mm maybe.

 

Okay, Toyota no longer makes the part. If I was to bend it around a can how do I figure out how long of a line should I purchase? Are all lines the same size?

 

It's way to fragile to stock and plus you can make and flare line yourself at the dealer tech level. To get a length, get some string or cord or something, start at a fitting and lay the string along the hardline as match it up as you follow the line until you get to the next fitting. then straighten the cord out and measure it. I would think you'll probably be in the 24-36" range. Then if you want to make a complete match, take the old line to your parts store and have them gauge the threads to find a match. I know the Napa near me has a a display case of assorted lengths of line with various ends on them already flared and ready to go.

When you bend line, slow and gentle is the way to go. You don't want to crimp the line and limit fluid flow internally.

 

Go on amazon search Nichol Cooper brake line, 3/16”. Flares are M10x1.00, use stainless steel. DO NOT GET ALUMINUM. NiCu is stupid easy to make lines with. Can burrow a flaring tool from Autozone.

 

Needed to replace entire lines to both front tires. Completely blistered and either leaking and/or about to burst and leak.
