line lock/roll control install on fc

[RX7V8Builder]

This is how I did it while still using the OEM proportioning valve:

After some time I installed a Wilwood adjustable proportioning valve.

I havent installed mine yet, but I bought 2 line locks and came up with this:


Also, instead of cutting my stock lines like shown in the pic, i just bought all steel braided lines for the front and appropriate AN - NPT fittings, etc.

I plugged the lower port on the MC,  put the LL after the stock proportioning valve,  and put a T after the LL. Used adapters and some AN3 hose, & didn't have to cut any stock lines, I just re-bent the LF line. I also scrounged up a 10mm brake line T from a Toyota corolla to make it work.

I can list part numbers if needed.

Bingo, the easiest way to do it, IMO.

I was just go to post the same question, I'm in the process of doing a solid rear 4 link setup with sub frames
bolted through the floor over the sheetmetal subframe and figured if I was going to have to bleed the brakes
anyway I might as well do the line lock at the same time. i thought about useing 2 solinoids but the single is
 cheaper   Thanks

rxv8builder  i like your set up, it seems simple.  the front port that points to the ground is what is feeding your line lock right?


andreS could u explain your idea more or draw a diagram please

Ok, so you are saying you plugged the LF Brake coming from master cylinder.  The line from prop valve to RF brake is where you installed the line lock and on the out put of the line lock you just T to both fronts?

Correct: 
The front bottom port in the MC is feeding the solenoid.
The front driver side port in the MC is feeding the OEM proportioning valve for reference (This line was later removed when installing Wilwood proportioning valve and port on MC was plugged) .
The LF and RF brake lines were bent and connected to a brass T fitting being fed from the line lock solenoid.
Top port of proportioning valve plugged.

ok perfect thanks, i may just do it your way when i install it. do you have a part number for the willwood prop , you installed ?

[RX7V8Builder]

I bought the kit from Flyin Miata.  The proportioning valve you can find almost anywhere.  This kit includes the adapters for metric brake line fittings and a metric union fitting.

thank you sir

[j_tizzle_84]

couldnt you plug the port for the Lf line, and install a line lock with two outlets after the proportioning valve eliminating the need for the line to have a t after line lock sol?

like this that has 3 outputs

When I did mine, I used two solenoids.
