gs1000 front brake reservoir

[Baz1954]

Guys/gals I'm back with another question re my 1978 GS1000. I'm overhauling my brakes replacing master cylinder internals and I want to replace the 'O' ring under the front brake reservoir. Tried putting it in hot water to see if expansion would help remove the reservoir but no it didn't. Somewhat wary of breaking the reservoir as I cannot find any online if I do. Do not want to replace assembly with rectangular type. Any ideas?

Thanks

Keep filling it up with boiling water. It should break free ok.

[Baz1954]

Will do Toni.

Thanks

Got it out with no damage. Four hot and cold dips.

Perseverance. Name of the game! Bits and pieces are getting far too expensive to break.

You should be able to buy a new reservoir from Suzuki

The originals tend to get brittle over time

Discontinued and couldn't find any on the net. Found OEM 'o' ring for it in Germany (again discontinued). It was still quite flexible although a little opaque compared to original.

Thanks for that Rijko, I'll save site in-case I have any problems. The 'o' rings site  I ordered from don't ship to Oz so going thru a buddy in UK. The shipping cost for that reservoir is a bit "out there" but if I have to I will.

Thanks

Couldn’t you have just made an o ring? And the OE price and shipping for that new res? Silly money! Get some sterilising fluid, used neat. Steep the old res. in it. That’ll whiten it up a tad!

Alright Tony. Humor this Yank and explain what sterilizing fluid is? Bleach? Rubbing alcohol?  

[Swiss Toni]

@slayer61It’s a sort of mild bleach. Commonly used for sterilising babies bottles and the like. 

[Baz1954]

I'll check out the 'sterilising'. As for 'o' ring I rate them as one of the greatest inventions ever. Used them a lot when I was a submariner. So prefer manufactured.

I wondered if there should be a comma after babies LOL.

I think he means hydrogen peroxide

[Baz1954]

Ok, thanks BigT will look into that.

I think I have a whole master cylinder, you can have it for the cost of postage. if you break it

[Baz1954]

I got it out Reinhoud  and I'm going to go the peroxide way to lighten it, I'll post result in a couple of days.

I love this site, access to info and parts as well.

Thanks for the offer.
