I am getting a warning on the message center that says "SERVICE BRAKE BOOSTER". I was thinking about changing the master but maybe the power steering pump is a good idea.
What year is your H2? Reason I ask is because the message you received SERVICE BRAKE BOOSTER is not intended for a vehicle equipped with a hydroboost. This message is intended for vehicles that use a vacuum booster. Do you have a way to pull DTC codes? There is no reporting of DTC relating to the hydroboost. Only fluid level has a sensor.
