What Are The Reasons For A Ford Parking Brake Failure?
A Ford vehicle's parking brake, often referred to as the emergency brake, plays a crucial role in securing the vehicle when parked, particularly on inclines. Ensuring its optimal functioning is not just a matter of convenience but a pivotal aspect of safety. However, like any mechanical component, the parking brake can face issues, and understanding the potential causes of a Ford parking brake failure can be invaluable for any Ford owner.
The Mechanism Behind The Parking Brake
Before delving into the reasons for malfunction, it's essential to grasp the basic functioning of the parking brake. In most Ford vehicles, the parking brake is a cable-driven system where the hand lever or foot pedal activates a series of cables that apply brakes to the wheels, usually the rear ones. This system operates independently of the car's main hydraulic brake system.
Common Culprits of Parking Brake Malfunction
Cable Wear and Tear
Over time, due to repeated use and exposure to environmental elements, the parking brake cables can become frayed or corroded. These physical changes can reduce the cable's efficiency, leading to a weak or non-responsive parking brake. In some instances, a corroded cable might snap, rendering the brake completely non-functional.
Incorrect Cable Adjustment
For the parking brake to function correctly, the tension in the cables must be accurately calibrated. If the cables are too tight, they might not release properly, causing drag. On the other hand, if they're too loose, the brake might not engage sufficiently to secure the vehicle.
Brake Shoe Degradation
In vehicles where the parking brake operates on the rear wheels using brake shoes, the wear and tear of these shoes can affect the system's performance. Over time, the lining of the brake shoes can wear down, reducing the friction needed for the parking brake to function effectively.
Contaminated Brake Fluid
While the parking brake system in Ford vehicles is mainly cable-driven, any contamination in the brake fluid can potentially affect the overall braking efficiency. Dirt, moisture, or other contaminants can reduce the hydraulic system's effectiveness, indirectly influencing the parking brake's performance.
Spring Mechanism Failure
The spring mechanism ensures the parking brake cables return to their original position, releasing the brake once the lever or pedal is disengaged. A malfunctioning or broken spring can prevent the parking brake from releasing, leading to continuous drag or an inability to engage the brake.
The Role of Regular Maintenance
As the adage goes, prevention is better than cure. Regular maintenance and inspections by certified professionals can help identify potential issues with the parking brake system before they escalate into significant problems. Ford recommends specific service intervals, during which various components, including the parking brake, are checked for wear and potential issues.
It's also prudent for drivers to be alert to any unusual signs when using the parking brake, such as reduced resistance in the lever or pedal, strange noises, or the car moving despite the brake being engaged. These could be early indicators of a problem that needs attention.
A Ford parking brake failure can compromise the safety and security of the vehicle, especially when parked on inclines. By understanding the common culprits behind such failures, Ford owners can be more proactive in seeking professional assistance when required. Regular maintenance and inspections, along with a keen sense of any operational anomalies, are crucial in ensuring the longevity and efficiency of the parking brake system.
