What to Do When the Brake Pedal is Hard to Press?

[NoraLee]

If the brake pedal is hard to press, it may be due to a leak or failure in the car's brake booster pump. Regular maintenance of the brake system is essential during normal vehicle use. Issues such as excessive impurities in the brake master cylinder, poor sealing, leakage in the brake master or wheel cylinders, failure of the vacuum booster pump, or overloading can all lead to brake failure. In addition to regular inspections and timely replacement of worn friction components, the brake system should also undergo proper periodic maintenance: 1. Clean the surfaces of brake friction components and their cooling channels with solvent-based cleaners; 2. Apply long-lasting protective agents to the rubber dust boots of the brake wheel cylinders and areas prone to rust; 3. Apply long-lasting lubricants to the contact surfaces between the tire rims and the car hubs; 4. Use high-temperature and impact-resistant lubricants on areas such as the back of the brake friction components and noise-damping shims.
