I thought my brake fluid level was going down so marked it with a pencil. Tonight upon checking it, a month after marking & 2000 miles later it has gone down about 1.5mm from where marked. Not much I know, but is this a problem? I've remarked it to see if it goes down again. Should the level remain constant. I presume it doesn't matter if I'm checking level when engine is hot or cold?
Cheers
