In the end the rear bias proved to be too much. I did remove the factory proportioning valve and replaced it with a Tilton adjustable biasing valve. It required a lot of front bias to overcome the cars tendency to lock the rears. Please be careful out there and remember to test your modifications thoroughly and in as many varied conditions as you expect to drive in (wet/snow/etc.)

+1 For removing the ABS.

I crashed 2 times in a nissan due to the ABS engaging in a lift-of-oversteer situation.
While sliding, I floored the brake pedal, instead of slowing down, it went with the nose straight forward into the railguards.

The moment when I floored the brake pedal the control of the vehicle was "lost" so
it was the last choice to make. Countersteering could not stabilize the car.

Generally I have the feeling that people driving cars without ABS have a more sensitive
braking foot. If you dont upset the balance of the car you can even brake very well
in corners.

I am happy my 7 has no ABS.

Did I read all the dates on this threads posts correctly? lol

But to add, I'd like to mention, ABS is your friend when driving in the rain

Yes you did.... I used this thread when I removed my abs like 3-4 years ago.

Correction: "But to add, I'd like to mention, properly working non-leaking, ABS is your friend when driving in the rain "

You did. I PM'd the OP as I am in the process of removing my ABS system due to a leaking pump. I'll be sure to add any relevant pics and info to this thread as soon as I am finished with the conversion.

One question though...I have a 88 T2 with the 4-piston front calipers. If I am replacing the ABS master with a non-ABS master cylinder, does the proportioning valve need to be replaced? I thought there was no difference between the ABS and non-ABS proportioning valves, but I am having trouble verifying this.

I had excellent success following this writeup!! I tried to document the process as best as I could in my thread ABS pump removal with pics. I feel the brake system is not an area to cut corners on, especially when removing a safety feature like ABS. While I wasn't able to keep the whole project below $100, I find the braking much firmer and stronger than before.

Many thanks to OP for providing part numbers and guidance on removing the ABS system!! This was the most helpful thread I found on converting to a non-ABS system.

Given the fact the thread started 14 years ago, I wouldn't hold your breath on the OP posting photos.
