Excessive Brake Pedal Travel (No Fluid Leaks and No Air in System) [06/2018 - ]: Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus ES 300h, 2023 Lexus ES 300h, 2022 Lexus ES 300h, 2021 Lexus ES 300h, and 2020 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

Depending on the malfunction, the skid control ECU (brake booster with master cylinder assembly) prohibits operation of the electronically controlled brake system to protect components and prevent incorrect operation when DTCs are stored.

If the switching solenoid is disabled due to prohibition of the electronically controlled brake system, the response of the brake pedal changes and braking performance is reduced.
