Master Cylinders and Brake lines
 |
Fisrt thing is to put the pedal assembly in the mount made a while ago, and then fit the 3 master cylinders - front brakes, back brakes and clutch. All are 3/4" bore Wilwood cylinders |
 |
There's a balance bar between the front and rear brake cylinders that will adjust how much bias, or pressure difference there is between the two systems. Front brakes do more than half the work, so the idea is to get all 4 wheels work at their optimum. The balance bar accomplishes much the same thing as a proportioning valve. |
 |
The master cylinders have 1/8 pipe threads and need adapters to fit 3/16 brake lines. The 90 degree adapter fitting is in the middle |
 |
Even though you don't have to tighten the brass fitting too much, it does deform easily when light pressure is applied. I threaded a brake line fitting with no brake line attached into the pipe-to-flare adapter to prevent crushing when it was tightened into the master cylinder. |
 |
Then, the fun task of making inverted double flares on the brake lines!
I used a double flare tool.  It takes a while and a bunch of tries to figure it out, but after some
time, I got pretty good at ti. The first step is to create the 'bubble'
at the end of the tube with the little black tool between the flare tool
and the tube-holder. |
 |
It creates this shape in the tube, and then... |
 |
The pointy end of the flare tool compresses the end of the tube and folds it down upon itself, creating.... |
 |
A nice double flare |
 |
I used welding rod to figure out the bends in the brake tubing |
 |
And then cut, flared and bent the tubing to fit |
 |
The pedals in the driver's side pedal box. |
 |
The clutch tube running down the firewall to the slave cylinder |
 |
The front right brake line |
 |
The front left brake line |
 |
The 3 cylinders and brake lines |
 |
I ran the rear brake tube through the firewall to the inside, where I'll place a "T" fitting |
 |
Here's the brass "T" fitting inside the dash. I've got a brake pressure switch that will thread into the fitting to light up the brake lights when the pedal is pressed. Flexible lines to the axle and the front calipers next weekend. I'll also clamp the lines down. |
