Firm up brake-pedal effort and keep power-assisted stops feeling smooth with the ADVICS Power Brake Booster BBT-088 (also written BBT088). It drops in as a direct-fit replacement for the 2004-2007 Toyota Highlander [All], using engine vacuum to multiply the force you apply at the pedal and pass it on to the master cylinder for confident, low-effort braking.
