Shimano GRX leaking shifter

[b1kes247]

Hello,

I recently noticed mineral oil will ooze out of area circled on top of left lever.
No signs of leaking anywhere else on
lever or on front brake caliper?

Bike has GRX 600 and is less than 3 months old.

Has anyone else experienced this issue or have any thoughts?

If bike is new and still in warranty that's a job for the shop that sold it to you.

If you have left it standing in very hot sun or a very hot shed you can get a little bit of leakage around the tiny breather hole due to the fluid expanding in the heat. Wipe away with IPA and keep a check on it

The Bike has been kept inside at room temp and consistently shows leakages after being wiped cleaned with IPA.

thanks for the response,

Looking to avoid lengthy warranty process, hopeful there is an easier fix or if someone else has seen this issue.

The thing is that you might invalidate the warranty by trying to fix it yourself .

In that case it may be that there is just a bit too much fluid in the brake - its not unknown for them to be overfilled at manufacture. You could try to letting a tiny bit out and see if that cures the issue.
