Sitting between the brake pedal and master cylinder, it multiplies the force from your leg so lighter pedal effort delivers strong stopping power. It installs as a direct-fit replacement for the 2001-2005 Lexus IS300 [All].
Signs this part may need replacing include a hard-to-press or mushy pedal, longer stopping distances, or a vacuum hiss at the booster.
