Symptoms

•Check engine light or brake warning light illuminated
•ABS warning light activated
•Unresponsive brake pedal or spongy feel
•Grinding or squeaking noises when braking
•Increased stopping distance or loss of brake effectiveness

Diagnostic Steps

1
Use an OBD-II scanner to check for any stored trouble codes related to the braking system.
2
Inspect the brake fluid level and condition; look for any leaks in the brake lines or master cylinder.
3
Visually check the brake pads and rotors for wear or damage.
4
Test the brake booster for proper operation by pressing the brake pedal while the engine is off, then starting the engine to see if the pedal sinks.
5
Check the ABS wheel speed sensors for dirt or damage and ensure they are properly connected.
6
Review the brake system's electrical connections for corrosion and secure fitting.

Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools: OBD-II scanner, brake fluid, socket set, torque wrench, multimeter, and cleaning supplies.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Navigate to the "Erase Codes" option on the scanner and follow the prompts to clear the error codes.
Disconnect the scanner after clearing the codes.

3. Inspect Brake Components

Remove the wheel to access the brake components.
Inspect the brake pads for thickness; replace if they are below 3mm.
Check the rotors for scoring or warping; machine or replace as necessary.
Verify that the brake fluid is at the proper level and top off if needed with manufacturer-approved brake fluid.

4. Test Brake Booster

With the vehicle off, pump the brake pedal several times to deplete the vacuum.
While holding the pedal down, start the engine. The pedal should move down slightly indicating the booster is functioning.
If the pedal does not drop, replace the brake booster.

5. Inspect ABS Sensors

Locate each ABS wheel speed sensor at the wheel hub.
Clean any debris or dirt from the sensor and its mounting area.
Use a multimeter to check the resistance of the sensor; consult the service manual for specific values.
If the sensor is out of specification, replace it.
