Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues while working.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket set.
Take off the wheel to access the brake system.

3. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper by loosening the caliper bolts with a socket set.
Sub-step 2: Carefully slide the caliper off the rotor and support it using a bungee cord or suitable hanger.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check the rotors for any scoring or warping.
Sub-step 2: If replacement is needed, remove the rotor by unscrewing any retaining screws or bolts.
Sub-step 3: Install the new rotor, ensuring it is aligned and secured.

5. Reassemble Brake Components

Sub-step 1: Reattach the caliper over the new brake pads and rotor.
Sub-step 2: Tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-30 Nm).
Sub-step 3: Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads and restore brake pressure.
Check brake fluid level and top up if necessary.
