Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, socket set.
Safely elevate the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by loosening the caliper bolts with a socket wrench.
2. Slide the caliper off the rotor and support it using a bungee cord or similar.
3. Remove the old brake pads; inspect for uneven wear or damage.
4. Clean the caliper bracket and rotor with brake cleaner.
5. Install new brake pads ensuring they are positioned correctly.
6. Reattach the caliper and tighten bolts to the manufacturer’s torque specifications (typically around 25-30 Nm).

3. Check and Replace Brake Rotors (if necessary)

Sub-steps:
1. Inspect the rotors for scoring or warping.
2. If damaged, remove the rotor by unscrewing the retaining screws (if applicable).
3. Install new rotors, ensuring they are properly seated on the hub.
4. Reinstall the caliper over the new rotor.

4. Fluid Inspection and Replacement

Sub-steps:
1. Check the brake fluid reservoir for level and color (should be clear or light yellow).
2. If the fluid is dark or contaminated, bleed the brakes and replace with new DOT 3 or DOT 4 brake fluid.
3. Follow the manufacturer’s bleeding procedure for the brake system.
