Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Wear safety gloves and goggles.

2. Brake Fluid Inspection and Replacement

Sub-steps:
1. Remove the master cylinder cap and check the brake fluid level.
2. If fluid is low, top it up with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
3. If the fluid is contaminated (dark or has particles), perform a brake fluid flush.
Tools Required: Brake fluid; funnel; turkey baster (for fluid removal)

3. Brake Pad and Rotor Inspection/Replacement

Sub-steps:
1. Remove the wheel by loosening lug nuts and using a jack to lift the vehicle.
2. Remove the brake caliper by unscrewing the caliper bolts and lifting it off the rotor.
3. Inspect the brake pads for thickness; replace if less than 3mm.
4. Check the rotor for grooves or warping; replace if necessary.
5. Install new pads and reassemble the caliper, tightening bolts to manufacturer torque specifications (usually around 25-35 ft-lbs).
Tools Required: Socket set; torque wrench; brake cleaner; wire brush (for cleaning)

4. Brake Line Inspection and Repair

Sub-steps:
1. Inspect all brake lines and hoses for cracks or leaks.
2. If any damage is found, replace the damaged section of the brake line.
3. Bleed the brake system to remove air using a brake bleeder kit.
Tools Required: Brake line cutter; replacement brake line; brake bleeder kit
