My current suspicion is that there is air in the system...and this is why. Before I started working on the ABS to put my 35th on the road my 89 had no brake problems...none, period. I changed the ABS assembly on the 35th, i got my brakes back...but i kept getting the brake/abs light combo when applying the brakes hard....meaning, new accumulator. Before buying it I decided to test it with my 89's accumulator which was also pretty new...and the problem on my 35th went away...except when the ebrake was applied....however, once I got a new accumulator and i replaced the accum. on the 89, the 89 started getting an ABS light.
As I remember I did a 'quick' bleed on the 35th b/c i was eager to get it on the road, and i didnt bleed the 89 once i replaced the accumulator...so im guessing that air is causing the lights. The 89 gets the light, and it goes away randomly..on and off, but the brakes are fully operational including ABS.
Two other things were suggested to me by members of the board. One, replacing the Ebrake sensor in the actual ebrake ratchet. I'll try that as I have like 3 spare ebrake ratchets. Also, Mr. ABS gury Duffy Floyd recomended changing the ABS computer. He agrees with me that there is no actual relation between ebrake system and ABS, so the computer might have an internal short making both lights pop up.
I just bought another car (yay!
- 92 tbird sport 5.0!) and since my brakes work on both cars, im going to probably hold off on the bleed for at lest a couple weeks. WHatever I find out, i'll post...and if somebody finds a solution, by all means post too.
