Context

I have a Merida Speeder 200 with a Shimano MT-200 hydraulic brake system, which uses BL-MT200 levers.

Over time these levers have developed a rattling sound. It appears to come from the lever rattling against its housing at the pivot point. Intuitively I would tighten the pivot bolt, but it appears to be a rivet, so I can't really do anything with it.

Things I've looked into

The answer to this related question mentions using an o-ring, but because of the rivet-like pivot I can't disassemble the lever.

The sound can be damped easily by just resting my fingers on the levers, but I sometimes prefer to just hold the bar without my fingers on the lever.

Question

Can I silence these rattling levers? Or is there perhaps a compatible lever that does not rattle?

  • Any chance to tighten the rivet? Maybe just by compressing it slightly in a vice?

    Maybe a thick grease pressed into the pivot? Something that will lubricate but also stay in place and dampen the vibrations?

    @Michael Bad idea in my opinion. It's not a true rivet, more of a press-fit pin. You wouldn't achieve much, and you risk cracking the lever body.

    Further to @NateW suggestion, some grease in between the lever and the pin would help, but maybe so would grease or a fibre washer between the lever and the body of the brake. Depends what is rattling on what.

  • It may be possible to make a new pin, but these are brakes and they absolutely must work when needed. If the rattling annoys you enough, replace the levers.

The lever of this specific model is not replaceable. So you can try your luck with a thick grease, or by "inserting" some layer of foam, or gluing little patches of old tubes in between the lever and the housing, close to the rivet.

The rattling is happening because of some play between the parts. The weight of your finger is enough to keep the parts in contact ---> replicate that by putting some material in between.
