What is the reason for the Hyundai ix35's brake pedal being hard to press?
1 Answers
The reason is air leakage or failure of the vacuum booster pump. The following is an introduction to the vacuum booster pump: 1. Overview: The vacuum booster pump, commonly known as the brake booster pump, controls the vacuum entering the booster pump during braking, causing the diaphragm to move. Through a linkage device, it uses the push rod on the diaphragm to assist human force in pressing and pushing the brake pedal, thereby amplifying the force exerted by the driver on the pedal. 2. Working principle: The vacuum booster pump utilizes the principle of air intake during engine operation to create a vacuum on one side of the booster. This generates a pressure difference compared to the normal air pressure on the other side, and this pressure difference is used to enhance the braking thrust.
