GS250T 1980. Need a new front brake caliper.

[Guest]

I’ve got a 1980 GS250T that I use for commuting I needed to replace the front brake pads, upon inspection it seems the caliper is off a 1978 Kawasaki and I can’t get pads for it anywhere.
I need to replace the caliper and pads with something that will do the job. Is there a “generic/ custom” replacement or has anyone got the oem caliper knocking around.
Any info will be appreciated
thanks in advance
Mark

Not mine, but there is one on ebay. Shipping is a bit high. Is the rotor stock?

To be honest I’m not 100% sure about the rotor. I’ll check it out when I’ get home tonight see if there’s a part # on it.
Thanks for the link but I see what you mean about the shipping

I got an 81 at home, probably the same, I will take a pic of the rotor for comparison later tonight.

80 and 81 are the same. I had both back in the day.

Here is my 81s brake rotor for reference. 20180724_193219.jpg

Looks like a zillion other Suzuki GS calipers. I believe this is the slightly bigger caliper used on many 1980+ single disk models and on the GK.

If you cross-reference the caliper and the caliper bracket, you might have better luck finding a caliper from a more common GS model.

Caliper is: 59300-45290

Bracket is: 59301-45841

Punch the part numbers in here, then click each of the "where used" links, and you get a list of models that used the same caliper:

https://www.onlinecycleparts.com/oemparts/partsearch/suzuki

Reference that against the models that used the same bracket, and you should end up with a longer list of possible swaps. The reason for going to the trouble is that Suzuki did some mix and match to adapt the same calipers to different forks, so you have to be careful about this. If your bike is wearing a Kawasaki caliper, then you need both the bracket and the caliper.

And when you buy a used caliper, 99% of the time you're also getting the bracket as well -- no one really separates them.
