With the news that my rear discs may have arrived at Andy's (need to call and confirm) I now need to start planning the install.

At the present time, I will be using the existing MC, adding an adjustable proportioning valve (inside car) and then routing to new calipers.

My initial thoughts are to go fully braided, but not sure if this is the best way, or if I should be looking at any hard lines. Also, what guage hose? I think it's -4AN, but I'm not sure.

I think your discs and calipers arrived at andy's on tuesday. -3 or -4 is recomended lines for brakes. Some MOT stations dont like you runing braided all the way through the car. I would check out www.inlinetube.com i have there s/steel hard lines on the pontiac and they look great

What's the difference between -3 and -4 (and don't say the size)

Obviously one will need more fluid to fill the system, but how does that affect operation?

What's wrong with running braided all the way?

I think its a couple of things. The first is the fact the line could come loose and get caught on something. This can be solved by running all the lines inside the car.
The second is to do with the fact they cant see if the line is damaged. Had this before at the local MOT station but argued and it was passed. All depends on the guy doing the test

But what are the differences? I guess the smaller diameter gives more braking force for the same amount of pedal pressure??

in which case why do the F1 teams run -8 for brakes?

Totally different technologies, you can't compare the two without knowing the differences.

Heat dissipation? Different MC sizes? They do have a very solid pedal.
