Solution

1. Preparation

Gather tools and parts needed for the brake inspection and replacement.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves to protect yourself.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper by loosening the caliper bolts (usually 12-15 Nm torque).
Sub-step 2: Carefully slide the caliper off the brake rotor and suspend it using a bungee cord to avoid straining the brake line.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Inspect the caliper for any leaks or damage; replace if necessary.
Sub-step 5: Clean the caliper bracket using brake cleaner and a brush.
Sub-step 6: Install new brake pads, ensuring they are oriented correctly and seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check rotor thickness with a micrometer; if below minimum spec, replace.
Sub-step 2: Remove the brake rotor by loosening the rotor screws (if equipped) or gently tapping it with a rubber mallet to dislodge.
Sub-step 3: Clean the hub surface where the rotor mounts.
Sub-step 4: Install the new rotor and secure with screws.

5. Reassemble and Test

Sub-step 1: Reinstall the caliper over the new brake pads and tighten the caliper bolts to manufacturer specifications.
Sub-step 2: Reattach the wheel and hand-tighten the lug nuts.
Sub-step 3: Lower the vehicle and torque the lug nuts to the specified value (usually 100-120 Nm).
Sub-step 4: Pump the brake pedal to seat the pads before taking the vehicle for a test drive.
