Spelli Posted December 9, 2021 Posted December 9, 2021 I am struggling to find a master cylinder repair kit for my 1980 gsx1100et. I have replaced all seals ect in both front and rear callipers and also the rear master cylinder but I can not seem to find a suitable kit for the front master cylinder. looks like the original is no longer available. Tourmax do one for the rear but not the front. all places I have tried so far have come to a dead end. Any advice about where I can find one? Is there an alternative kit that in which the seals would fit ? Quote

Mike711 Posted December 9, 2021 Posted December 9, 2021 Check the piston diameter, that kit's for a single disc so it's likely to be smaller than for an 1100. Quote
Spelli Posted December 9, 2021 Author Posted December 9, 2021 Thanks for the input. I will give the seller a call in the hope he can measure it for me. I can only hope. Quote

Is this the right part number? how can you check if it is correct ? Quote
Spelli Posted December 9, 2021 Author Posted December 9, 2021 (edited) I have checked the part number listed on the cms web site and that part number from goparts looks correct. that is absolutely fantastic success. What a ⭐️ Thanks Mike. Edited December 9, 2021 by Spelli Quote

Spelli Posted December 9, 2021 Author Posted December 9, 2021 Part is ordered. carriage is a bit steep at €20.00 but it is a lot better that trying to cobble something together from Mis matched parts. let’s just hope it is the right one when it comes !!! Thanks again for the help Mike. Quote
Spelli Posted January 17, 2022 Author Posted January 17, 2022 So just an update on previous saga. Goparts have eventually come back to me after about 5 weeks to tell me the GSX master cylinder repair kit is not available and is refunding the money. I found another supplier in Australia who has 3 in stock but will not export the part because it is in short supply and is saving them for his long term loyal clientele. ( fair enough. ) does anyone have any other suggestions as to how I might track down the part or any alternative ideas as to how I might solve this issue….. ie alternative pattern parts / visually similar master cylinder that might be available.

Poldark Posted January 17, 2022 Posted January 17, 2022 Do you need to keep everything original? If not, there are plenty of aftermarket master cylinders and newer model salvage options. A friendly hydraulics repair shop might be able to help you find the piston rings for your original master cylinder. 1 Quote
TonyGee Posted January 17, 2022 Posted January 17, 2022 Im sure their will be plenty of bikes that use the same size seals but its finding out which ones are the same ????? have you got a friendly bike shop you could take them too so they can compare ? Quote
TonyGee Posted January 17, 2022 Posted January 17, 2022 just had a quick look and theirs a few suzuki's use the same size. gs1000 1980 gs500 1980 gs650g 1980-83 and others. P.N. 59600-49810 / 59600-49811 the OEM kit is no longer available but their are after market kits out their. the piston might not look the same as OEM but as long as the seals are the same size this looks like it'll work.

Spelli Posted January 17, 2022 Author Posted January 17, 2022 Toni, can I ask you, how did you manage to cross reference the part numbers to discover they are used in other machines? Quote

TonyGee Posted January 17, 2022 Posted January 17, 2022 only kidding I use this site but it didn't come up with much, but after a google search another site came up with the info. # SUZUKI MOTORCYCLES - Genuine Spare Parts Catalog (bike-parts-suz.com) Quote
bomberone Posted February 10, 2022 Posted February 10, 2022 How did you get on with sourcing a front brake repair kit or replacement unit? Did you get a repair kit for the rear? I'm in a similar position with a std Katana, rear needs a repair kit & front needs replacement master cylinder. Quote

Hi, bomberone, I am still struggling with getting a repair kit for the front master cylinder. There is a company in France that is listing the part as available but having had a less than happy experience Will ordering the part from goparts in the Netherlands I am a bit weary. Their digital footprint looks a bit off so I am not going down that line. I am currently looking at a similar looking kit for a GS1000 and hoping the seals might fit. a repair kit for the rear master cylinder is available from Tourmax so you shouldn’t have a problem with that. I think the only option for a front master cylinder is either a used part or to try to get one that looks similar. Please let me know how you get on. It would be interesting to compare notes.

bomberone Posted February 13, 2022 Posted February 13, 2022 Ta Spelli, Took a look at Tourmax, as you say several Suzukis using MSR301 for the rear kit, so that's sorted. Also shows a front kit MSB301 for gs1000/850 but guess that's the cylindrical reservoir... Quote
Joseph Posted February 14, 2022 Posted February 14, 2022 Tourmax quality overall is iffy at best Quote
no class Posted February 14, 2022 Posted February 14, 2022 made in Japan ( apparently)….. bought a kit for the Katana ….. looks to be legit Quote

It is really appreciated Edited February 15, 2022 by Spelli Quote
