To restore the brake travel, start the vehicle and wait for the idle speed to stabilize (about 2-3 minutes). Then, firmly press the brake pedal all the way down for two seconds and pull up the handbrake. Maintain the pressure on the brake pedal for a few more seconds without releasing. Finally, slowly release the brake pedal and release the handbrake. If there's no change in the brake travel after this procedure, it's essential to visit a repair shop promptly to diagnose the exact issue.
Extended brake travel in cars is usually caused by issues within the brake system, including brake fluid contamination, wear in the hydraulic brake system, brake pads, and brake discs. One of the more common problems is moisture contaminating the brake fluid. Most modern vehicles use a hydraulic brake system, which has entirely replaced the older cable-driven brake system. However, the reservoir for brake fluid isn't entirely sealed, and a small gap exists. This allows moisture from the air or external sources to seep into the brake fluid.
The vehicle's brake system relies on the coordination of brake discs, brake pads, and brake fluid. If there's air within the brake system, the response time will be prolonged, leading to reduced braking efficiency. Moreover, an insufficient amount of brake fluid will also result in longer brake travel. Over time, a portion of the brake fluid may evaporate. If there's not enough brake fluid, the braking effectiveness decreases, posing a safety risk. It's recommended for vehicle owners to periodically inspect the entire brake system. Also, during driving, it's wise to maintain a reduced speed and keep a safe distance from other vehicles.
