Line lock question

[mebe007]

Ok so I got all the adapters and lines to install my line lock. Hers the question. I got a factory dia hard line but it has smaller fittings with adapters I have to use to get the fitting large enough to plumb into the master cylinder. It's 3/16 line. I also git lines with proper size fittings but the line dia is larger than stock. So should I run the larger line with right fittings to the line lock from master cylinder or run the 3/16 line with adapters from line lock with adapters?

I'm sort of confused...
the line for your front brakes is a 3/16" correct? The fitting for it the goes to the master is larger than a standard 3/16" fitting?

here's my setup...

I cheated a bit and plumbed it before the proportioning valve. The rear brake line has a adjustable proportioning valve on it cuz the factory one is fading...

the front brake line is a 3/16", the fitting on it for the master I believe is a large 9/16" fitting, but the fittings below for the linelock are all standard fittings, which go into a 1/8" NPT adaptor for the linelock.

I would just use the larger line. The more fittings you use the more chance of a leak you will have :idea:

I believe what he is reffering to is that he has 1/2"-20 threaded 3/16" nuts on his factory brake line (at the master cylinder) the standard 3/16" brake line nut would be a 3/8"-24

you are correct. i know the larger line will be harder to bend but i am was thinking it would be nice to minimize connections. just didnt know if it would change the pressures or anything like that.

If there is a change in pressure, I don't think it'll be noticeable. Plus, it'll be going right back down to 3/16" line :idea:

I could be wrong here, so somebody correct me if I am :arrow:

whats the best way to seal the npt adapter threads? teflon tape, or some other thread sealant?

I used teflon tape no problems as of yet.

sounds like a plan. gonna see if i can tackle it tomorrow. just need to figure out where exactly i want to mount it.

 

[khan0165]

had I not cheated and routed it after my proportioning valve, I would mount it to the firewall. It would be too much plumbing to bring it back up to the fender.

you could also mount it where my Summit proportioning valve is mounted, on the plastic fender well

Ended up using the 3/16 line as it was easier to bend and I had a 90deg adapter which made things much easier
