Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment such as gloves and goggles.

2. Raise the Vehicle

Using a jack, lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspection: Using a caliper gauge, measure the thickness of the rotors. Look for signs of warping.
Replacement Steps:
1. Remove the caliper bolts using a socket set and lift the caliper away from the rotor.
2. Secure the caliper using a bungee cord to avoid stress on the brake line.
3. Remove the rotor by unscrewing the retaining screws or simply sliding it off if there are none.
4. Install new rotors by reversing the removal steps. Torque the retaining screws to manufacturer specifications (usually around 10-15 lb-ft).

4. Inspect and Replace Brake Pads

Inspection: Check brake pads for uneven wear or damage.
Replacement Steps:
1. Remove the brake pads by sliding them out of their brackets.
2. Compress the caliper piston using a brake caliper tool to make space for new pads.
3. Install new pads, ensuring they are oriented correctly.
4. Reattach the caliper over the new pads and torque caliper bolts to specifications (typically around 25-30 lb-ft).

5. Reassemble and Lower the Vehicle

Reinstall the wheels and torque lug nuts to the manufacturer’s specifications (usually around 75-85 lb-ft).
Lower the vehicle and remove jack stands.

6. Final Checks

Pump the brake pedal to ensure proper operation before driving.
Check for any visible leaks or issues after reassembly.
