So the Master Cylinder conversion and brake line replacement are finally complete. I have bled the system and am almost finished (ran out of spare fluid till tomorrow). I have posted some photos just for reference if anyone want to see them. I don't want to hear anything about my not so handy brake line bending work. It was my first time so you know, they might not be very elegantly bent. :)

I have 1 question left. I have ONE last leak that only acts up when a moderate amount of pressure is applied to the pedal. It's coming from one of the fittings going into the distribution block. It appears to be coming out of the threads, and not the hole in the top. Does this jump out at anyone as something I could easily fix? I checked to make sure it was nice and tight but with my open end wrenches I am a little scared to tighten too much since I mildly stripped them getting the whole thing together. Would a line wrench help me much in that area? Anyway someone please please let me know what you think about this leak. I am pulling my hair out over it. :)

I agree with the above, but suspect that if it is coming out of the threads then the correct wrenchs will solve the problem.

This was discussed recently. On double flare fittings, no amount of teflon or pipe dope will fix the problem.

DONT use teflon tape or any liquid sealant, this is a flared fitting and your life will depend upon it. Get a new length of tube, bend it as required (leaving enough room for the flaring tool), then go to a brake and clutch shop and pay about $5 each end to have it flared by a pro. Good luck

When I installed my SSBC front disk kit, they provided a plug for one of the dist block outlets. I could not get the plugged outlet to stop leaking. Tried everthing. At a local auto parts store, I found a 3-way block for about $12. and it has worked great. Point is, you probably have to change the block but check locally as the dist blocks from the Mustang suppliers are about $50.

Don't like those rear brake lines with dual exhaust. You need to replace the body line and use the GT dual exhaust brake hose and bracket.

While I agree that teflon tape or thread compound shouldn't be used on brake fittings, the purpose of teflon tape or thread compound is not a sealant but a lubricant for the threads.
