Understanding Brake Pedal Drops
A brake pedal drop occurs when the brake pedal suddenly drops or sags when the engine is started. This can happen due to a range of reasons, from worn-out brake pads to faulty brake master cylinders. In some cases, the drop may be accompanied by a grinding or screeching noise, which can be a sign of more serious issues.
It’s essential to understand that brake pedal drops are not always a cause for concern. However, if left unchecked, they can lead to more severe problems, such as brake failure, which can have catastrophic consequences. As a responsible car owner, it’s crucial to identify the root cause of the issue and address it promptly.
Common Causes of Brake Pedal Drops
There are several reasons why a brake pedal might drop when the engine starts. Here are some of the most common causes:

Brake Caliper Issues: The brake caliper is responsible for applying pressure to the brake pads. If it’s faulty or worn out, it can cause the brake pedal to drop.
-
Worn-out Brake Rotor: A worn-out brake rotor can cause the brake pedal to drop. This is often due to excessive heat buildup or improper brake pad installation.
-
Brake Hose Issues: The brake hose is responsible for carrying brake fluid from the master cylinder to the brake caliper. If it’s damaged or clogged, it can cause the brake pedal to drop. (See Also: Brake Pads How Many Km? Ultimate Guide)
