Air Brake Abs Warning Light Problems of Chevrolet Astro

I have a 4 year old chevy Astro van with a kelsey hayes ebc unit. Recently the abs light started coming on from time to time when the engine had been running for a while, but it would go off when the vehicle was turned off and restarted cold. I had my brake system checked and there was nothing wrong with the brakes. The code indicated a bad relay in the computer control system. The problem is that it causes the abs light to come on and when that happens I have no abs working. This could cause a safety issue under certain braking conditions. The light doesn't come on all the time so the question is do I pay over $900 for something that I believe to be a manufacturing defect or do I take a chance that when I need my brakes that the abs system will work. As of now, I have not replaced the part. The dealer indicated that the part # was 12478045 . This part cannot be purchased except through a dealer. It is their product.

I have had many electrical problems with my Chevrolet Astro van. 2000 year model. I have only 60,000 miles and it's been in for changing of oxygen sensor twice a new catalytic converteer installed in the first 4000 miles. At 7000 miles I had to have some connector replaced because my van would go for about 5 miles and then just die on me, like no getting fuel. Now for the past 6 months I am having a problem with my brake and abs lite coming on and when I put on the brakes they grab and let go and it takes a long time to stop. I have taken it to many places and everyone tells me they can't find nothing wrong. I had it hooked up to the see what the computer fault was and it says the relay. The relay is 800. 00 dollars and the mechanic says it may still not be the problem.
