Brakke lines and brake fluid.

OK, So all the brakes are put back together. We now need to replace all the brake lines. Remember we already installed the front lines when we had that part jacked up. So, now it's just from the Cross member to the rear wheel cylinders that need to be done.



One of the rear brake lines was actually made out of copper. This is both illegal and unsafe. Unsafe because copper will not stand the pressure in a brake system. Illegal because of that fact.


So, we start with the Left Rear, up over the pumkin, to the junction block.


Next come the Right Rear to the junction block.


Next is the Felxable hose to the frame.


Last it the Frame Line to the front Junction block.



FINALLY, The BRAKES are completely together. Now it the time to bleed them. Bleeding brakes is the processes of removing all AIR from the brake lines, and replacing it with brake fluid. Brake fluid is nasty stuff. If you want to remove paint from ANYTHING, use brake fluid. It also turns into water inside brake systems. This is not a good thing. Water has Oxygen. Water and oxygen causes rust. Rust stops brakes from working.

BUT.. a new brake fluid is on the market. It is called DOT 5. it is based on Silicon. Much nicer on paint. Won't attract water. won't rust. Just what Antique cars need.

Remember that hole in the floor for the master cylinder? Well, THAT is where you add/check your brake fluid. NOT easy for those full service gas stations.

First we add Brake fluid. We need to be careful as DOT 5 brake fluit is about $80.00 a gallon.


Next we call dad. He will PUMP the brake pedal to build pressure to push the air out. This takes about 2 hours. and, Dad's leg gets real tired.


FINALLY, We have BRAKES...

Tomorrow, we will talk about cleaning the interior, and getting the lights to work.
