5 Reasons Why You Should be Concerned About a Hissing Sound from the Brake Pedal

A hissing noise from the brake pedal is a common issue that is often caused by a faulty master cylinder. This can occur when there is a buildup of air in the brake lines, or when there is an issue with the seals in the master cylinder. The hissing sound can often be heard when pressing and releasing the brake pedal, or even when the vehicle has been idle for some time. If left unchecked, this issue can lead to increased braking distances and decreased overall performance of the brakes. To fix this issue, it is recommended that a qualified mechanic inspect and replace any faulty components as necessary.
