Solution

1. Preparation

Gather tools and replacement parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to ensure safety while working on the brake system.

2. Remove Wheel

Use a socket set to loosen the lug nuts of the wheel with the braking issue.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel and set it aside.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or fluid leaks.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged or excessively worn, remove the old rotor by unscrewing any retaining screws.
Install the new rotor, ensuring it is properly aligned and secured.
Clean the rotor surface with brake cleaner to remove any residue.

5. Reassemble Components

Reattach the caliper over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (often about 76 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
