Les Schwab Tire Center review: brake service

First of all, I have been a loyal Les Schwab customer since 1976. In 2012 I had the Les Schwab in Warrenton OR do a complete front end brake rebuild on my Ford F350. In 2014 I had a caliper lock up and luckily made it to the shop for repairs. I had a 3 year warranty which covered the repairs. Last week [protected]) the same caliper locked up and, thankful that I had no accident, made it to the shop once more. I was informed that the warranty was from the original service (2012) and, although I was within the three years, I was 1000 miles over the allowed 25, 000 miles. I had to pay, once again, for the repairs. What's wrong with this picture? What about the repairs that were done a year ago? Since I was in a bind, I reluctantly paid for the services. I would like a store credit to use for future transactions - I still think the service is great!
