⚠️ Safety Warnings

Important safety information - read before proceeding

•Always park on a flat surface and engage the parking brake.
•Use caution when working with brake fluid, as it can damage vehicle paint and be harmful if ingested.

Symptoms

•Brake pedal feels spongy or soft when pressed
•Longer brake pedal travel before engagement
•Increased stopping distance
•Possible brake warning light illuminated on the dashboard
•Unusual sounds during braking (e.g., grinding or squeaking)

Diagnostic Steps

1
Check brake fluid level by inspecting the brake fluid reservoir for adequate fluid levels and check for contamination.
2
Inspect brake lines for leaks, cracks, or corrosion that could lead to loss of pressure.
3
Assess the condition of brake pads and rotors for wear or damage.
4
Perform a brake pedal pump test to determine if air is present in the brake lines.
5
Use an OBD-II scanner to check for any related error codes that might indicate electronic brake system issues.

Solution

Solution

1. Preparation

Gather tools and safety equipment.
Wear safety glasses and gloves.
Ensure the vehicle is parked on a level surface with the engine off.

2. Brake Fluid Inspection

Tools Required: Brake fluid tester, clean cloth.
Remove the brake fluid reservoir cap and check fluid level.
If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Wipe any spilled fluid immediately, as it can damage paint.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleeder screws, clean cloth.
Start with the wheel farthest from the master cylinder (usually the rear passenger side).
Have an assistant pump the brake pedal several times and hold it.
Open the bleeder valve on the brake caliper to release air and fluid until a steady stream appears.
Close the bleeder valve and have the assistant release the brake pedal.
Repeat for each wheel in order: rear passenger, rear driver, front passenger, front driver.
Ensure the brake fluid reservoir does not run dry during this process.

4. Inspect and Replace Brake Pads (if needed)

Tools Required: Socket set, torque wrench, brake pad spreader.
Remove the wheel and inspect the brake pads for thickness.
If worn beyond specification, remove the caliper and replace the brake pads.
Reassemble and torque the caliper bolts to manufacturer specifications.

5. Final Reassembly and Testing

Reinstall the wheel and lower the vehicle.
Test brake function by pressing the pedal several times to ensure it feels firm.
Check for any leaks around the brake components.
