Highlander low brake fluid
Summary of the thread
A 2012 Toyota Highlander Hybrid owner noticed consistently low brake fluid levels and unusual brake pedal feedback. Despite checking for leaks around the master cylinder and calipers, no obvious issues were found. A suggestion was made to inspect the brake pads and rotors, as worn components can cause fluid levels to drop. Following a brake inspection, it was confirmed that worn front brakes were the cause, and replacing them resolved the issue.

Thanks for the tip! That makes sense. How quickly did you notice your fluid dropping, and did the brake warning light come on?

The fluid dropped gradually over a few weeks but no warning light. I'd get it checked by a workshop to be sure the brake system is still working correctly and isn't leaking. Turns out for me, it was just worn brakes as I suspected.

Appreciate the help! I booked a brake inspection. Turns out, it was indeed worn front brakes like you suggested. Got the brakes replaced, along with a fluid replacement, and the total came to 480€. All good now.

Hey, I had something similar happen with my Highlander. I'd check your brake pads and rotors. When they wear down, the brake fluid level drops as the calipers have to extend further. It may be worth a quick brake inspection.
