Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it on jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and hang it using a wire to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the rotor for grooves or damage; replace if necessary.
Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Check and Replace Calipers (if needed)

If calipers are sticking, remove them from the bracket.
Examine the caliper piston for corrosion or damage.
If necessary, replace the caliper with a new or remanufactured unit.
Reinstall the caliper over the new brake pads.

5. Reassemble

Reattach the caliper bolts and torque them to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Brake System Bleed (if applicable)

If air was introduced to the brake lines, bleed the brakes using a brake bleeder kit.
Follow the proper bleeding sequence and ensure the brake fluid is at the correct level.
