Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Locate the caliper and remove the caliper bolts with a socket wrench.
3. Carefully slide the caliper off the brake rotor without disconnecting the brake line.
4. Inspect the brake pads for uneven wear and replace if necessary.
5. Install new brake pads, ensuring they are properly seated.
6. Reattach the caliper and torque bolts to manufacturer specifications (typically around 25-30 Nm).
7. Replace the wheel and lower the vehicle.

3. Brake Fluid Inspection and Replacement

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the brake fluid level and condition; it should be clear and at the appropriate level.
3. If the fluid is low or contaminated, drain the old fluid using a brake bleeder kit.
4. Refill with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
5. Bleed the brakes to remove air from the system.

4. Caliper and Brake Line Inspection

Sub-steps:
1. Inspect the brake calipers for proper movement and functionality.
2. Check for any leaks in the brake lines, paying attention to connections.
3. If a caliper is sticking, it may need replacement.
4. Tighten or replace any damaged brake lines.

5. Suspension Component Check

Sub-steps:
1. Visually inspect suspension components, including control arms and bushings.
2. Look for any signs of wear, cracks, or damage.
3. Replace any worn or damaged parts with OEM or high-quality aftermarket components.
