You did not fix the problem. Replace the MASTER cylinder. It is not an ABS problem, stick to the basic hydraulic system.... that is where the problem is.

I would think if it is both rear wheels it is the master cylinder but if it is only one it might be the caliper. Jerry in Ohio

sides are the same age and likely to go at the same time, thus he didn't like to do just one unless it was due to some accident rather than normal wear. He said that sometimes when just one is replaced that the other one with then blow out. So next week I'm having the other one done...or at least checked for its condition. Is that the way you deal with the caliper thing? e.g., replace both back ones at the same time?

You don't normally need to do that, but if the car has a long service life behind it, it's not a bad idea to do them both.

PS The fixing one side, makes the other side blow a week later theory is crap.

That is why you have a dual master cylinder: front and rear are independant of each other. Look at your reservoir. You will see 2 chambers. The large chamber is for the front brakes, they have larger calipers. The small chamber is the rear brakes. It is usually at the booster end of the master. The master has two plungers in it, not one for both. Here is a break down pic of a tandem master cylinder: [it is a VW but it is same idea]

When you say that the brakes "stick", are you saying that the calipers grip the rotors and don't release when you take you foot off the brake? Have you had the calipers checked? They are pretty old at this date. If the brake fluid is correct, and the master cylinder is working, physically examining the calipers would be a good idea. Given the expansion flexibility of rubber brake lines, braided stainless over teflon gives a much better feel when braking, as do Zimmerman cross-drilled rotors (front) with Rotex Gold brake pads (coximport.com) which don't make the front wheels black at all!
