Important safety information - read before proceeding

•Always wear safety glasses when working on brakes.
•Allow brake components to cool before inspection or repairs to avoid burns.

Symptoms

•Check engine light illuminated
•ABS warning light on the dashboard
•Brake pedal feels soft or spongy
•Unusual noises during braking (squealing or grinding)
•Vehicle pulling to one side during braking
•Increased stopping distance

Diagnostic Steps

1
Scan the vehicle's onboard computer using an OBD-II scanner to retrieve any stored trouble codes related to the braking system.
2
Inspect brake fluid level and condition in the master cylinder reservoir.
3
Check brake pads and rotors for wear or damage.
4
Examine brake lines for leaks or corrosion.
5
Test the brake booster for proper operation.
6
Verify the functionality of the ABS module and associated sensors.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Socket set
•Torque wrench
•Brake fluid
•Brake cleaner
•Basic hand tools (screwdrivers, pliers)

Parts Required

•Brake pads
•Brake rotors (if worn)
•Brake lines (if damaged)

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear tires for safety.

2. Retrieve Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note down the trouble codes displayed on the scanner.

3. Inspect Brake Components

Brake Fluid Level:
- Open the hood and check the brake fluid level in the master cylinder.
- If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Brake Pads and Rotors:
- Remove the wheel to access the brake caliper and rotor.
- Check the thickness of the brake pads; replace if below the manufacturer's minimum specification (usually around 3mm).
- Inspect the rotor for scoring or excessive wear; replace if necessary.

4. Check Brake Lines

Visually inspect the brake lines for any signs of leaks, cracks, or corrosion.
If any damage is found, replace the affected brake line(s) as needed.

5. Test the Brake Booster

With the engine off, pump the brake pedal several times to deplete any vacuum.
Start the engine and press the brake pedal; it should feel firmer and drop slightly underfoot, indicating the booster is functioning properly.

6. ABS Module and Sensor Verification

Inspect ABS wheel speed sensors for dirt or damage.
If necessary, clean or replace the sensors.
Clear the DTCs using the OBD-II scanner and perform a test drive to check for reoccurrence of codes.
