So I bought a 5th Gen Prelude. I am going to run it in ITS. We can not run ABS in ITS so I a thinking that instead of disconnecting the unit, I want to get rid of the ABS module.

I heave searched and searched and searched. All I have seen is "ABS Delete engine bay tuck bro!" "Use 40/40 prop valve." etc...

My question is how do your properly set up your brake lines when removing ABS? The master cylinder has two lines (I assume one that controls the front and one that controls the rear brakes). These two lines head into the ABS module where technology does it's work and then it divides it into 4 lines one for each corner. Great.

When I delete the ABS, to I use a "T" fitting from the "front" line of the master to the front two brakes and then another "T" fitting to the rears from the rear master cylinder feed? Where is the correct position to plumb a cockpit adjustable brake proportioning valve? On what line does it get plumbed to?

TIA,

J

 

Actually, the OEM lines in your car are diagonal circuits. One line will drive the front left and rear right, the other will drive the front right and rear left.

When you redo the lines. Run one output to a T fitting and then to each wheel in the front. For the rear, run it to the brake pressure limiter (it limits pressure, does not adjust brake proportioning) then to a T fitting and then each wheel.

 

Yes. They are in an X pattern. The actual routing is as follows:
MC front and MC rear go to ABS module. From ABS module, 2 lines go to each front caliper and 2 lines go to a proportioning valve. From here, two outlets go to rear brakes. I'm just not sure what the rear prop valve actually does...

I agree that it seems that if I go form the front MC feet to a T to both fronts then from rear MC feed to adjustable prop valve to a T to rear calipers.
