Cadillac Repair/Teves brake system

Question
I have a front wheel drive 1990 Fleetwood with the teves brake system on it. The abs light comes on and I can hear the pump running, brake pedal feels soft. This has the accumulator with it. The system is very expensive. Is there someone who rebuilds them or what would you recommend for fixing it. Would a leaking brake line cause this to happen. Thanks and please help.

Answer
Hello,

I have some bad news for you. I haven't had the nightmare of dealing with the teves system for at least 5 years and at that time I was told these units were no longer being rebuilt.
The unit can give you a spongy pedal.
As for a leak, if the master is full, you do not have a leaky line.
Normally I do not recommend junk yard on such a unit, but you may consider it as an option.
GM had many anti lock issues over the years. My 1998 olds had run with the yellow anti lock and red brake light for many years and I do not even know what system that has. Never looked, never cared because the brakes work good except for the anti lock function.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
