Brake fluid going down in reservoir

[LCPLPunk]

Hey all, so I've noticed over the last few weeks my brakes feel a bit weaker and the fluid in the reservoir keeps slowly dropping. I did a quick eye/hand check around the calipers and don't see any fluid around the connections and I also looked around the reservoir and didn't see anything. After doing a bit of research I read that the system could be leaking into the brake booster.

Are there any other places I should check?

How do I find where this leak is?

And, how hard/costly is it to replace the brake booster if I need to?

Just a thought; when brake pads wear thinner, the caliper pistons require more fluid. Therefore, the fluid in the master cylinder reduces.

If you cannot find a leak, that is not necessarily bad but an indication you need to check pad thickness.

I would at least bleed your brake system and if you haven’t done so in the last 2 years. Plan to do a brake fluid bleed/replacement.

Good luck and hope you don’t have bigger issues.

It's going down much quicker than it should, unless I am loosing like a good portion of my brake pad every time I drive the car (which is pretty much M-F) then I'm not sure it would be because of that, BUT, you never know!
