Brake pad size for GS850 79 or earlier

[Jan]

I am currently overhauling the front brake caliper on my GS400L. It was very dificult to find spares for this model. But now i have managed to get a new dustcap and sealing ring as original spares, they was ok priced. But the brake pads was § 260,-/set, whitch is a 1/3 of the hole bikes value.
It seems as The GS 850 before 79 also have circular pads, and those pads i can get as non-original spare part ($43). Does any one know the diameter of the GS850 79 brake pads?? If they are too big in dia, I will be able to machine them smaller.

Best regards
Jan

Hi Mr. Jan,

Compare the part numbers. Suzuki did use similar parts across several bikes. The EBC part number for the '79 GS850G front brake pads is FA35. The manufacturer part number is 59300-44860 (supersedes: 59300-45890 and 59300-45891). What year is your bike? For the non-US GS400 you can look up the part numbers here: http://www.cmsnl.com/search/index.ph...gs400&spbmvin=

Hi Jan,

That's good news. Suzuki is known to have different part numbers for very minor differences, like if only the color is different on the same part. And a 0.3mm difference in size is probably another one of those minor differences that they thought deserved its own part number. It's just the way they do things.


Thank you for your indulgence,
