Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Check and Replace Brake Fluid

Sub-steps:
1. Open the master cylinder reservoir cap.
2. If fluid is low, use a siphon to remove old brake fluid.
3. Replace with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
4. Bleed the brakes if necessary using a brake bleeder kit.

3. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Remove the wheel by loosening lug nuts and then lifting the vehicle with a jack.
2. Detach the brake caliper and hang it using a wire to avoid strain on the brake line.
3. Remove the old brake pads and inspect for wear.
4. Check the rotors for scoring or warping; replace if necessary.
5. Install new brake pads and reassemble the caliper, ensuring proper torque on bolts (typically 25-35 ft-lbs).
6. Reinstall the wheel and lower the vehicle.

4. Repair or Replace Brake Lines and Hoses

Sub-steps:
1. Inspect brake lines for corrosion or leaks.
2. If damaged, replace the affected brake line/hose with OEM parts.
3. Bleed the brake system after replacing lines to remove air.

5. Test the Brake Booster

Sub-steps:
1. With the vehicle off, pump the brake pedal until it feels firm.
2. Start the vehicle and check if the pedal sinks slightly; this indicates the booster is functioning.
3. If it does not, replace the brake booster.
