Am looking to start my brake system on my mk indy. Are there any good guides on plumbing tips dos and donts ect.

Thanks

Buy a decent flaring kit.

Wot he said ^^^^^

A decent flaring tool makes it a much less frustrating task.

Also make sure you put the connectors on the pipe before you make the flare - this is usually done ust after you've perfected the perfect flare

It's helpful to map out the route of your pipes with stiff wire.

Make any bends gradually and avoid sharp bends as this can kink the inside of the pipe. I used a small hand pipe-bender for a neater finish but you can manage with with thumbs - it just takes practice.

Good luck

If your using a pressure switch for the brake lights then mount it so that the pressure sensor is horizontal rather than vertical as its harder to bleed the system if its vertical because it can trap air bubbles.

Use Kunifer, nothing else.

Do an eBay search for Powerhand brake flairing tool.

Use oem style push-in clips rather than p-clips.

On longer pipe runs it is often an idea to use male to male pipe joiners as this can make fitting the pipes a lot easier.

I have these brembo master cylinders and they have 3 holes in I know the top one is for my resivour but why two more outlets?

If they are both for your brakes, presume they are designed to run seperate pipes to each caliper?

An easy way to work out the length of pipe runs is to use a long Bowden outer cable , it's flexible so can be clipped into place just use a piece of insulating tape wrapped around it to. make the length needed

As above ^^ use stiff wire - actually wire coat-hangers unbent did the job for me.
Also second the idea of joining short runs not only as they are easier to bend but easier to replace if anything goes wrong in the future.
Practise male and female flares before attempting any runs - saves on pipe in the long run.
Finally ensure you have enough clearance in the transmission tunnel if you are using a live axle - you'd be surprised how much up and down movement there is.
Having said that the brake system was probably one of the most satisfying things I did on the build....
HTH.

Practise doing single and double flared ends.

When making the lines allow about 5 cm extra in case you f%%% up an end and need to redo. Will be easier to cut it off and start again than join pipe if too short - not rcommended - else redo the whole length ... so do the longest runs first so they can be reused for the shorter ones if need be and not needing too much unbending.

Used round item e.g. bottles, cans jars as formers for a neat finish.

Finally make sure the hollow bolt is fitted before you make the flare.
