I bought the parts to rebuild all three brake calipers I thought for my 88 GL1500??? When you bring up the fiche for the front brake parts the right one is the first one you see. I just thought that both front calipers are the same? WRONG... The pistons are different sizes. I have a extra set of seals for the right caliper if anyone needs them. Just send me a PM and I will mail them in the US for free. Thanks :?
