Diagnostic Steps

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, C-clamp or brake caliper tool, brake cleaner, bungee cord or rope.
Ensure the vehicle is parked on a level surface, engage the parking brake, and disconnect the battery (negative terminal).
Gather all necessary tools and parts before starting.

2. Raise the Vehicle

Use a lug wrench to loosen the lug nuts on the wheel where brake pads will be replaced (do not remove completely).
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (usually two bolts) and remove them using a socket.
Carefully slide the caliper off the brake rotor. Use a bungee cord to hang the caliper from the suspension or frame, ensuring not to stress the brake line.

4. Remove Old Brake Pads

Identify the old brake pads and their retaining clips.
Remove the pads from the caliper bracket.
Inspect the caliper bracket for any debris or corrosion, cleaning if necessary.

5. Compress the Caliper Piston

Use a C-clamp or brake caliper tool to gently compress the caliper piston back into the housing.
Ensure the brake fluid reservoir cap is removed to allow fluid to return without overflow.

6. Install New Brake Pads

Apply brake grease to the backing of the new pads (if needed) to prevent noise.
Position the new brake pads into the caliper bracket, ensuring they fit securely.
Reinstall the caliper over the new pads and secure it with the mounting bolts. Torque the bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).

7. Reassemble the Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and remove the jack stands.
Tighten the lug nuts to the manufacturer's torque specification (typically around 75-85 ft-lbs).

8. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure the brake pads seat properly and restore brake pressure.
Check the brake fluid level and top off if necessary.
