Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent accidental deployment of electric components during repair.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
C-clamp or brake caliper tool
Multimeter (for electronic components if needed)

2. Remove Wheel and Brake Components

Sub-step 1: Loosen lug nuts slightly before lifting the vehicle.
Sub-step 2: Use the jack to lift the vehicle and place jack stands for safety.
Sub-step 3: Fully remove the lug nuts and take off the wheel.
Sub-step 4: Remove the brake caliper by unscrewing the caliper mounting bolts.
Sub-step 5: Carefully take off the brake pads from the caliper bracket.

3. Inspect and Replace Parts

Sub-step 1: Examine the brake rotors for warping or scoring; replace if necessary.
Sub-step 2: Inspect caliper for signs of sticking; clean or replace as needed.
Sub-step 3: Install new brake pads, ensuring they are of equal thickness and quality.
Sub-step 4: Clean the caliper bracket and apply anti-squeal lubricant to the back of the new pads.

4. Reassemble Brake Components

Sub-step 1: Reinstall the brake caliper over the new pads and torque the mounting bolts to the manufacturer's specifications (refer to service manual for exact torque values).
Sub-step 2: Reattach the wheel and hand-tighten the lug nuts.
Sub-step 3: Lower the vehicle back to the ground and torque the lug nuts to the specified value.

5. Final Checks

Sub-step 1: Reconnect the battery.
Sub-step 2: Pump the brake pedal a few times to ensure proper pad seating.
Sub-step 3: Start the vehicle and check for any warning lights or unusual noises.
