- Spongy Brake Pedal: A spongy brake pedal can be a sign of a faulty brake booster. If the pedal feels soft or squishy when pressed, it may indicate that the brake booster is not functioning properly.
- Brake Pedal Travel: If the brake pedal travels further than normal when pressed, it may indicate that the brake booster is not providing enough pressure to slow or stop the vehicle.

How to Check the Brake Booster
Checking the brake booster is a relatively simple process that can be done at home or in a garage. Here’s a step-by-step guide on how to check the brake booster:
Step 1: Locate the Brake Booster
The brake booster is typically located under the dashboard, near the brake master cylinder. You may need to remove some trim panels or dashboard components to access it.
Step 2: Check the Brake Booster Diaphragm
The brake booster diaphragm is responsible for amplifying the driver’s foot pressure on the brake pedal. To check the diaphragm, look for any signs of wear, cracks, or damage. If the diaphragm is damaged, it may need to be replaced.
Step 3: Check the Brake Booster Vacuum Hose
The brake booster vacuum hose connects the brake booster to the engine’s vacuum system. Check the hose for any signs of damage, cracks, or leaks. If the hose is damaged, it may need to be replaced.
Step 4: Check the Brake Booster Mounting
The brake booster is mounted to the firewall or dashboard. Check the mounting points for any signs of wear, cracks, or damage. If the mounting points are damaged, they may need to be replaced. (See Also: How Do I Know if I Need a Brake Flush? Signs To Watch Out For)

Step 6: Check the Brake Booster for Leaks
Check the brake booster for any signs of leaks, such as oil or brake fluid leaks. If the brake booster is leaking, it may need to be replaced.
