I am having a problem with my front master cylinder on my 2012 Carbon Red. It keeps leaking, I got it replaced last weekend for a new one but I have noticed it is still leaking. It looks like it is coming from the very small hole in the lid. Any ideas. Thanks Eddie.
The hole is the breather for the space above the seal, to allow air in as the pads wear, so I would have a look at the seal to make sure it’s not leaking into the space between the seal and the lid.
