what a brake pedal kick back is and why it’s a problem
A brake pedal kick back is a phenomenon that occurs when a vehicle’s brake pedal suddenly moves or “kicks back” when pressure is applied to it. This can cause the vehicle to jerk or lurch unexpectedly, which can be dangerous and make it difficult for the driver to control the vehicle.
It can also cause the brake system to fail, which can lead to accidents or collisions.
Brake pedal kick back is generally considered to be a problem because it can compromise the safety and control of the vehicle.
Causes of brake pedal kick back:
There are several possible causes of brake pedal kick back. Some of the most common causes include:
- Worn out brake pads: Brake pads are the components of a vehicle’s brake system that are responsible for creating friction and stopping the vehicle’s wheels. Over time, brake pads can wear out and become less effective. When this happens, the brake pedal may feel spongy and kick back when pressure is applied to it.
- Faulty brake calipers: The brake calipers are the components of a vehicle’s brake system that squeeze the brake pads against the rotor to create friction and stop the vehicle. If the brake calipers are sticking or not functioning properly, they may not release the brake pads as they should, causing the brake pedal to kick back.
- Air in the brake lines: The brake lines are the pipes that carry brake fluid from the brake pedal to the brake calipers. If there is air in the brake lines, it can cause the brake fluid to become aerated, which can cause the brake pedal to feel spongy and kick back when pressure is applied.
Other possible causes of brake pedal kick back include a faulty master cylinder, a leaking brake booster, or a problem with the brake system’s hydraulic system. In some cases, brake pedal kick back may be caused by a combination of these factors.
Symptoms of brake pedal kick back:
When a vehicle’s brake pedal is kicking back, the driver may experience a range of symptoms. Some common symptoms include:
- A spongy or soft brake pedal: When a brake pedal kick back occurs, the brake pedal may feel soft or spongy when pressure is applied to it. This can make it difficult to stop the vehicle smoothly and control the brake force.
- Difficulty stopping the vehicle: Because the brake pedal is not responding consistently, the driver may have difficulty stopping the vehicle when needed. This can be particularly dangerous in emergency situations, where quick and precise braking is necessary to avoid accidents or collisions.
- Sudden jerking movements: When the brake pedal kick back occurs, the vehicle may suddenly jerk or lurch unexpectedly. This can be disorienting for the driver and can make it difficult to maintain control of the vehicle.
In some cases, brake pedal kick back may also cause the vehicle’s brake system to fail completely, resulting in a loss of braking ability. This can be extremely dangerous and should be addressed as soon as possible.
Solutions for brake pedal kick back:
There are several possible solutions for brake pedal kick back, depending on the specific cause of the problem. Some common solutions include:
- Replacing the brake pads: If the brake pads are worn out, they will need to be replaced. This will restore the brake system’s ability to create friction and stop the vehicle’s wheels effectively.
- Servicing the brake calipers: If the brake calipers are sticking or not functioning properly, they will need to be serviced by a mechanic. This may involve cleaning and lubricating the calipers, or replacing them altogether.
- Bleeding the brake lines: If there is air in the brake lines, it will need to be removed by bleeding the brake system. This involves using a specialized tool to remove the air from the brake lines and replace it with fresh brake fluid.
In some cases, brake pedal kick back may be caused by a combination of these factors, in which case multiple solutions may be needed. It is important to have a mechanic diagnose the specific cause of the problem and recommend the appropriate repairs.
