man I know you want to fix a 50 dollar problem for like 50 cents but save your money and your time and get some re-manufactured calipers. Usually it is not the boots but rather the internals of the calipers which are rusted or have lots of brake dust build up. If you can not do it now then apply that 6-8 bucks you were going to spend on boots to getting the calipers. I have never been able to save an old caliper and 20 year old calipers need to be replaced any way.
