Front caliper corrosion

[a_morti]

M in sc I think you have the right idea. I am really satisfied with the front brake, it doesn't need a big caliper. Assuming it's otherwise ok when the pads need changed I will probably do that.

Octane it's a good idea but they're well past that. You'd rub the rust off and since there's no plating there you just leave bare metal to rust.

its a common modification to old bikes. Let me know if you find a source, should be pretty easy to find a shop to do it. good luck!

You could also look at getting the pistons chromed. That shouldn't cost too much and will keep them from rusting. They should have been chromed in the first place or made from stainless.

Real close, like half a mile.

It just lives outside without a cover.

I am aware that doesn't help, .

You live 1/2 mile from the ocean, and leave your GROM outside under a cover... What do you expect ??? That is going to rust the shit out of anything !!! Given reports, the GROM is more susceptible to corrosion than most bikes, which is why you should EXPECT this kind of thing and worse. I would NEVER leave my GROM outside... Given where you live, If you do not want you GROM to be a useless pile of rust, keep it in your living room ! It is tiny enough to even put in a closet

You quoted me saying without a cover but don't let that get in the way of a good rant.

I live on the fifth floor.

Thanks for your helpful comments (y)

You could also invest in a bike cover would help a little bit I'm sure but it really should be inside. With you on the 5th floor that won't happen unless you get a garage. Only options would be new stainless pistons, brembo or chrome the stock pistons and re hone the piston bores.

I spent a while shopping eBay for a master cylinder suitable for my bigger caliper for cheap. I settled on a Honda 599 master cylinder - it's used to drive 2x small sliding calipers (25.3mm pistons, same as grom) so should work well on my big Brembo with 30+34mm pistons.

I found one for good money and it came with a pair of calipers, so I am planning to try out the caliper from a 599 on the Grom. It's still Nissin, it's still a sliding design, but it uses an alloy carrier and is just generally a better quality longer-lasting piece. Anyone already tried that, or have the parts around to give it a shot?

It'll have to wait til my folks visit me from UK... Mid-October. I'll update here, ofc.
