    Front caliper rebuild kits? '78 GS750 E

    Seems like Powerhouse in UK at nearly $50 (!) is the only supplier for these--is that right? Or have I missed other options?
    thanks

    You can order the parts from any Suzuki dealer or OEM parts site. If you're after the stainless steel pistons, they may only be available from a UK (or maybe EU) company.

      Those parts seem to be discontinued through Suzuki. The good news though is that the later year calipers are a direct bolt on and they work better. Parts support is better too.

        Wemoto has complete rebuild kits. Nessism is right though. The early calipers aren’t really that great.

          Good to know, what years are you referring to exactly?

            1980 onwards. Bolt for bolt fitting, but if you're buying used (and you will be) make sure they're off a NON-L model, as the brackets on the L models are different, although the calipers are the same.

              Ok thanks. Does the pitting on this piston look too extensive? No vertical scoring.

                  Ah geez. Wonderful. Back to ebay, or the used parts forum... at least powerhouse has the pistons too, if I stick with these.
                  Thanks everyone.

                    Have you checked Brake Crafters yet? They sell good kits with stainless parts that should last a long long time. https://www.brakecrafters.com/

                      Yeah, they only show brake pads for my bike, nothing else. Thanks

                        I wonder if you gave them the measurements if they could find one that's the same?

                          Worth asking, I guess. I emailed them to find out. They do show several 38mm OD sizes, though the original Suzuki service manual specifies 38.105mm minimum service limit, so they'd have to be checked exactly for that spec, no?
