•Reduced braking performance or responsiveness
•Unusual noises when braking (squeaking or grinding)
•Brake pedal feels spongy or too firm
•ABS (Anti-lock Braking System) light activated

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to retrieve specific brake-related codes.
2
Inspect brake fluid level and condition in the master cylinder reservoir.
3
Visually inspect brake pads and rotors for wear and damage.
4
Check for leaks in brake lines and connections.
5
Test the brake booster for proper operation.
6
Verify the operation of the ABS system by checking the wheel speed sensors.

Solution

Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to ensure safety while working on the braking system.

2. Fluid Check and Replacement

Sub-steps:
1. Remove the cover of the master cylinder reservoir.
2. Check the brake fluid level; if low, top up with manufacturer-recommended brake fluid (e.g., DOT 4).
3. If the fluid is contaminated or old, perform a complete brake fluid flush.
  - Use a brake bleeder kit to remove old fluid from each brake caliper.
  - Refill the master cylinder with new brake fluid and bleed the system until clear fluid is observed.

3. Brake Pad and Rotor Inspection/Replacement

Sub-steps:
1. Remove the wheel to access the brake assembly using a socket set.
2. Inspect brake pads for thickness; if less than 3mm, replace them.
3. Check the brake rotor for scoring or warping; replace if necessary.
4. Install new brake pads, ensuring they are properly seated.
5. Replace the rotor if needed, ensuring proper torque specifications (typically 80-100 ft-lbs for rotor bolts).

4. ABS System Check

Sub-steps:
1. Reconnect the battery and use the OBD-II scanner to clear any existing codes.
2. Start the vehicle and perform a road test to ensure the ABS system functions correctly.
3. Monitor the ABS light; if it remains illuminated, additional diagnostics may be required for wheel speed sensors or the ABS module.
