Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the vehicle is powered off and the key fob is removed from the vicinity.

Tools Required:

Torque wrench
Socket set
Brake pad spreader or C-clamp
Jack and jack stands
Screwdriver set
Brake cleaner
Gloves and safety glasses

2. Lift the Vehicle

Sub-step 1: Loosen the lug nuts on the front or rear wheels slightly while the vehicle is still on the ground.
Sub-step 2: Use the jack to lift the vehicle and secure it with jack stands.
Sub-step 3: Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Sub-step 1: Locate the caliper mounting bolts and remove them using the appropriate socket.
Sub-step 2: Carefully slide the caliper off the rotor. Do not let the caliper hang by the brake line; support it with a bungee cord or similar device.
Sub-step 3: Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Sub-step 1: Clean the caliper and rotor surfaces using brake cleaner.
Sub-step 2: Apply brake grease to the backing of the new brake pads to prevent noise.
Sub-step 3: Insert the new brake pads into the caliper bracket.

5. Reassemble the Brake Assembly

Sub-step 1: Compress the caliper piston using a brake pad spreader or C-clamp until it is fully retracted.
Sub-step 2: Slide the caliper back over the new pads and rotor.
Sub-step 3: Reinstall and torque the caliper mounting bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

6. Reattach the Wheel

Sub-step 1: Place the wheel back onto the hub.
Sub-step 2: Hand-tighten the lug nuts.
Sub-step 3: Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications (usually 100-120 ft-lbs).

7. Final Checks

Sub-step 1: Pump the brake pedal several times to ensure proper brake function and to seat the new brake pads.
Sub-step 2: Check the brake fluid level and top off if necessary.
