So let's begin.
First up mount the handbrake. This I can't help much with as every car is different but post me a picture up and I can try and advise where to put it
Here's mine
Quick bit of info for you about the master cylinder
The rear hole is the feed side and the front hole is the output side. Its backwards but thats how it is
Once its mounted you need to pop your 7/16s reducer on and flare your pipe
Then wrap the first 3 or 4 threads closest to the bolt head in PTFE. Or whatever you prefer. And bolt it into the feed side of the your master cylinder
Then bend the pipes how you need em
Now wielding 25ft of copper pipe isnt easy so time to cut it down. I had mine poking out the firewall through a grommet. So I measured from this grommet back to a point I picked at random.
I then laid the tape out and cut the string at this length
Then tape the string at the point you measured to.. mine was here
Then trace the string along the copper pipe... slow and steady and dont pull the string off the pipe or it will throw the measurement out. Then mark the end
Prepare to cut
There's a knack to this... dont just wind it tight and turn or you'll end up pushing the sidewall creating a D shape. Wind it so it bites and do a quarter turn. Spin the cutter... quarter turn... spin the cutter etc until you end up with a clean cut
Then trace your pipe through your selected grommet. Then flare a fitting on. I used a female fitting
Repeat the flaring process for your outlet pipe
I ran my outlet pipe into a T-Piece
Then I continued to trace my pipework to the rear
I drilled holes behind the fuel tank. Take care to definitely avoid the fuel tank
Pop grommets in the holes and bend your pipe with a 90 up then a 180 down. One single 90 down wont work it puts too much stressed on the pipe and you risk kinking it.
My grommets went walkies so I put some polyurethane vac pipe around my copper pipe temporarily. Hopefully you've got the grommets to be used
Next attach your brake pipe on the end and and tighten it up (my little fittings haven't turned up so I've used jubilee clips for now to replicate it
That's as far as I've got... it got too dark to be messing with attaching the pipes up so that's tomorrow. But it's a start
For those mounting their pipes under the car. Its the exact same principles. Except you'll go around your tank not over it like me
The pipes will want mounting on the drivers side of the tunnel. Use pop rivets and p-clips. You wont want self tapping screws poking through your floor
