Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, flashlight, safety gloves, and eye protection.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a lug wrench to loosen the lug nuts of the front or rear wheels.
Jack up the vehicle and place jack stands under the appropriate locations to secure it.
Remove the wheels to access the brake components.

3. Inspect Brake Pads

Sub-steps:
- Locate the brake caliper and visually inspect the brake pads for thickness. Pads should be at least 3mm thick to ensure safe operation.
- If worn below this threshold, replacement is necessary.

4. Inspect Brake Rotors

Sub-steps:
- Check the rotors for scoring or grooves, which can indicate wear or overheating.
- Measure the rotor thickness with a micrometer; it should meet or exceed the manufacturer's minimum specifications.
- Look for any warping by visually inspecting for uneven surface wear.

5. Check Brake Fluid

Sub-steps:
- Remove the brake fluid reservoir cap and check the fluid level. It should be between the minimum and maximum marks.
- Inspect the fluid for contamination or discoloration; if dirty, consider a fluid flush.

6. Inspect Brake Lines and Calipers

Sub-steps:
- Visually check brake lines for leaks, bulges, or cracks.
- Inspect calipers for any signs of leakage around the pistons or seals. If leaking, caliper replacement may be necessary.

7. Reassemble and Test

Replace wheels and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer’s specifications.
Test the brake system by pressing the brake pedal before driving to ensure proper engagement.
