LX470 Brake Issue (1 Viewer)

More mechanically educated compatriots, any idea on why the brakes look like they're low on fluid after pressing the pedal a few times, but return to full if the vehicle sits a while? Bad master? Something else? There is inconsistent amounts of dead play in the pedal before the brakes engage depending on usage. Brakes were bled and serviced ~3000 miles ago. Pads and rotors were replaced on all four corners at the same time. There are no visible leaks under the vehicle. Thanks!

Should've clarified in the original post but it's an '01 with about 239k on it. Thanks

The brake fluid level does that because the fluid fills the accumulator. If you look closely at the brake fluid reservoir, it has instructions how to read/fill brake fluid.

Bleeding this master cylinder and getting all the air out of the system (and ABS) can be a bit more tricky than other vehicles. Might be worthwhile to take it to a Toyota specialist to bleed.

Got it, thank you!!
