I have an S50 swapped 318is with an ABS system with a mind of its own. Every 10 stops, it feels solid and exactly as it should. The other 9 stops, the pedal is harder than normal, and the ABS pulses almost immediately and locks up the front wheels unevenly, which unsettles the front end of the car.
The ABS is powered through pin 20 of C101 with a RD/WT power wire.
The system has
1. New reman brake booster
2. Known functioning 23mm MC
3. Brand new soft lines (all six)
4. Rebuilt calipers on all four corners
5. Fresh pressure bleed
Is this a case of a balky ABS solenoid? Or is it a brake proportioning valve problem, where the valve is blocked sometimes, but othertimes not? I think this could be the case because the old MC did have some wear on the rubber grommets, which I assume could have deteriorated, shedding little rubber bits into the brake system?
