The brakes on your vehicle are one of the most critical safety features, and ensuring they are functioning properly is essential for safe driving. One of the key components of a well-functioning brake system is the brake pedal free play. Free play refers to the amount of movement or “give” in the brake pedal before it begins to apply pressure to the brake pads. Adjusting the brake pedal free play is a crucial maintenance task that can help prevent brake failure and ensure your vehicle stops safely.
When the brake pedal free play is set too high, it can cause the brakes to become less effective, leading to longer stopping distances and increased risk of accidents. On the other hand, if the free play is set too low, it can cause the brakes to become over-sensitive, leading to premature wear on the brake pads and other components. Properly adjusting the brake pedal free play is essential to ensure your vehicle’s brakes are functioning at their best.
