RC brake fluid dropping

I've got a 2020 Lexus RC with a gasoline engine and my brake fluid level seems to be dropping quicker than I'd expect. I'm getting some strange feedback from the brake pedal, almost like a soft or spongy feeling. I've checked around the master cylinder and lines for any visible leaks, but haven't spotted anything obvious. Could this be related to worn brake pads, maybe requiring more fluid to compensate? Mileage is at 112997 km. Any ideas before I dive deeper?

Hey, I had a similar issue with my RC, though I can't remember the exact year. I noticed the brake pedal feeling weird too. Have you had a brake inspection recently? Could be worth checking the pads and rotors.

Thanks for the quick reply! When you had the spongy pedal, did you also notice the brake fluid level dropping? And did replacing the pads/rotors solve the issue, or was there something else going on with your brake system?

Yeah, the fluid was definitely low, and topping it off only helped for a short while. For me, replacing the worn pads sorted everything out. I'd suggest taking it to a workshop to get it checked out properly though, just to be safe.

Appreciate the insight! I'll definitely get the brakes inspected ASAP. Turns out the worn brakes were indeed the culprit! Got the pads and rotors replaced for 480€, and the brake pedal feels normal again. Thanks for the help!
