•Ensure the vehicle is secure and cannot roll while working on the brakes.

Symptoms

•Brake pedal feels spongy or soft underfoot
•Decreased braking effectiveness
•Brake warning light illuminated on the dashboard
•Longer stopping distances
•Brake fluid leakage around the wheels or under the vehicle

Diagnostic Steps

1
Inspect the brake fluid level in the master cylinder reservoir.
2
Check for any visible leaks in the brake lines or around the brake components.
3
Examine the condition of the brake pads and rotors for wear.
4
Test the brake booster operation by pumping the brake pedal with the engine off, then starting the engine to see if the pedal sinks.
5
Use a brake bleeder kit to check for air in the brake lines.
6
Scan the vehicle's onboard diagnostics (OBD-II) for any related trouble codes.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid reservoir. If the level is low, top it off with the manufacturer-recommended brake fluid type.
Check for leaks; replace any damaged seals or components if found.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench
Start with the wheel farthest from the master cylinder (typically the right rear).
Attach the bleeder kit to the brake bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and old fluid; close the valve before releasing the pedal.
Repeat the process for each wheel (right rear, left rear, right front, left front).
Ensure to periodically check and refill the master cylinder reservoir during bleeding to prevent it from running dry.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, new brake pads/rotors (if necessary)
If the brake pads are worn down or the rotors are damaged, remove the wheel and inspect.
Remove the caliper and brackets, replace the brake pads, and resurface or replace the rotors as needed.
Reassemble the components and torque them to the manufacturer's specifications.

5. Test Brake System

Tools Required: None
After all repairs are completed, conduct a test drive to ensure the brake pedal feels firm and responsive.
Monitor for any unusual noises or behaviors during braking.
