Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Brake pad replacement kit (if needed)

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is still on the ground.
Raise the vehicle using the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it dangle from the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper for damage or sticking.
If replacement is needed, install new brake pads in the bracket.
Ensure that the pads are oriented correctly (check for wear indicators).

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotors for any grooves or warping. If damaged, remove the rotor by unscrewing the retaining screws.
Clean the new rotor with brake cleaner to remove any protective oil.
Install the new rotor and secure it with the screws.

5. Reassemble Braking System

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque value.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts in a crisscross pattern.

6. Final Checks

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