[Healeys] Brake line

Mon Jul 23 07:06:49 MDT 2018

My search turned up the following

Hygroscopic is the ability of a chemical compound to absorb or adsorb water. 

A hydroscope is a device, similar to a telescope built for observing things underwater.

DOT 5 is a silicone-based fluid and is separate from the series of DOT 2, 3, 4, 5.1. It is immiscible with water, and with other brake fluids, and must not be mixed with them. Systems can only change fluid after a complete system changeover, such as a total restoration.
It contains at least 70% by weight of a diorgano polysiloxane[3]. Unlike polyethylene glycol based fluids, Dot 5 is hydrophobic.[4] An advantage over other forms of brake fluid is that silicone has a more stable viscosity index over a wider temperature range. Another property is that it does not damage paint.[citation needed]

Silicone is hydroscpic too.
I intend to replace all the lines and hoses. Brake and clutch rubber hoses have been replaced. Where do I get a prebent set for the 67 B I'm working on or my 100-6 for that matter?

My 2 cents , on a car and it’s parts over 50 years old . Start thinking about replacing all of the lines , along with the clutch line and oh the fuel line . And oh the oil gauge line also , cause when it goes your going to have oil all over your drivers floor. 
  You can get a complete set of stainless steel lines, for all the above , pre bent , and replace them as needed . 
       I did this to my 67 BJ-8 along with switching over to silicone brake fluid . Never have to worry about any issues with this kind of thing again . 
        Good Luck , Don

Hi Ira,

    Pipe bending is an art that I haven't really mastered, but I've done    OK by pulling the old line, and using a brake pipe bending tool to    replicate--or possibly improve--the original pipe routing.  Steel    brake line is cheap, so buy extra to practice with--it will probably    take a couple tries to get it right--and switch to stainless or    cunifer if you prefer after you get the hang of it.  Oh, and don't    forget to put the fittings on before you flare the ends; it's    painful to get a couple flares just right then realize there are no    fittings (someone told me that once).  I think getting good flares    is even trickier than bending.

    Based on the condition of that one line, I wouldn't trust any of the    other brake lines in the car.

Finally getting to work on the 67 B I bought for        my wife. Seller told me a metal brake line was cracked and        leaking...turns out the someone tried to braise a patch on the        line and it leaked. Any advice on bending the replacement line        to match the old one?
