Solution

1. Preparation

Tools Required: Socket set, brake cleaner, torque wrench, multimeter, jack stands, tire iron.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Check and Replace Brake Fluid

Inspect the brake fluid reservoir for proper levels.
If fluid is low or discolored, drain old fluid:
1. Locate the brake fluid reservoir.
2. Use a turkey baster to remove old fluid.
Refill with manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
Bleed the brakes using a brake bleeder kit to remove air from the lines.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader.
Remove the wheel using a tire iron.
Remove caliper bolts and lift the caliper away from the rotor.
Inspect the pads for wear; replace if less than 3mm thick:
1. Remove old pads by sliding them out of the caliper bracket.
2. Insert new pads, ensuring proper orientation.
Reattach the caliper and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotors for thickness and any signs of warping or scoring.
If replacement is needed:
1. Remove caliper and pads as described above.
2. Unbolt the rotor from the hub.
3. Install new rotor, ensuring it is clean and free of oil.
4. Reassemble caliper and pads.

5. Check and Replace Brake Lines (if needed)

Inspect brake lines for any signs of wear or leaks.
If damaged:
1. Use a wrench to unbolt the old line from the caliper and master cylinder.
2. Install the new line, ensuring it is securely fastened.
3. Bleed the brake system after replacement.

6. Optimize Regenerative Braking Settings

Access the vehicle’s settings through the infotainment system.
Navigate to the driving settings and adjust regenerative braking levels to enhance performance.
