Abs delete

Ok so after much thought blood sweat and cursing I decided to completely delete the abs system. It is way to far out of my budget to repair it would need a complete overhaul. So I am asking for help in rerouting the lines to the master cylinder. Can I use an 83 master cylinder pre-abs? Or can I use my existing master and reroute my lines? Does anyone have just a schematic of the brake lines? Thanx all

Just drive it. Why re-route? Those things are designed to operate even if electrics fail.

So lemme get this straight: you've got money to reroute all the lines to the master cylinder and replace the master cylinder, but you don't have the money to rectify any issues you have with the ABS system as it sits? Sorry but I don't understand that logic.

The brakes on a 928 are among the best put on a car year to year. Why not just fix it correctly? We can help diagnose your issues.

Do as Chris says, just pull the fuse on the ABS - then you have no ABS.

It's a little late for that I had to cut the lines to the abs unit in order to remove it. It is now out. Is there a tool to reflange the lines or do they have to be replaced?

And BTW the passenger front caliper was replaced, the braided flex lines were replaced and it still would not shoot fluid out

Mind you I did pull the fuse first and I still had no rotor grip on the front passenger. It was definitely an internal abs solenoid issue

For all who may be interested I successfully deleted abs from the car as I never liked abs for the most part and tend to feel for the cars breaking point in traction minus rainy situations. The abs brake control unit had 5 lines in.... Two that go to the master, one for each front wheel and one line to the rear. I rerouted the three lines to the wheels to go to the master with only two inputs to the master I made a tee coupling then cut and reflanged all the lines.

Sounds like a redneck approach. Hope you do better with the rest of the car. Tell us you at least used double flares.

Isn't there a proportioning valve in there someplace? Front and rear need different pressure don't they?

Double flares? - I thought 928 brake lines were bubble flares.

Redneck? Yes I am with a sprinkle of Italian, I live in the south so when in Rome...lol yes 928's are bubble flares but when hooking up to a tee for the front you have slim pickings and must adapt accordingly. A proportioning valve should not be needed as it has a basic one from factory and also the wider wheels in the rear staggered fitment need that more grip to begin the deceleration process.

Continually amazed by what I read here. Please tell me this car is going to be used on a closed course track and not on the streets. What you have done here is put the brake bias at 50%, which is a **** ton more than it should be and in any emergency situation you have a high chance of losing control of the car.
