Hello,
Last week I did brake fluid flush on our 2022 Pilot. This was the first time I opened the master cylinder cap, in the less of 3 years of owning the car.
The brake fluid was very dark.
Under the strainer, the lip of the reservoir, was very dirty - looked as if dirt was sucked in from the outside.
The cap rubber seal was not sitting flush on the cap, but one side was pulled away from the cap.
I flushed the system and cleaned the dirt.
I am not sure what the issue is here - defective cap seal or/and defective cap or/and reservoir or/and poor assembly at the factory.
In any case, I decided to replace the cap seal (with aftermarket, direct replacement for the exact Honda part). When I went to replace it, the OEM seal, again was not flush with the cap. Will see how the aftermarket one will work.
Tried to raise the issue with dealer ... got some nonsense that it is normal to have dirt like that, and if there is a leak from the cap I will be getting warning lights.
Has anyone seen something like this on a less than 3 years old car?
Is there a way to quickly check if the cap itself maybe bad?
The top edge of the master cylinder, where the rubber seal contacts the cylinder plastic body, is all smooth. No irregularities.
