2
Check brake rotors for scoring, warping, or damage.
3
Examine brake calipers for proper operation and any sticking.
4

Solution

1. Preparation

Tools Required: Jack and jack stands, tire iron, socket set, brake cleaner, protective gloves, safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Remove Wheel

Loosen the lug nuts with a tire iron while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check the brake pads for thickness; if below 3mm, they need replacement.
- Examine the brake pad backing for any irregularities or damage.
Replacement (if necessary):
- Compress the caliper piston back into the caliper housing using a C-clamp.
- Remove the old pads and install new brake pads, ensuring they are properly seated.
- Reattach the caliper and torque the bolts to manufacturer specifications (typically around 25-30 Nm).

4. Inspect and Replace Brake Rotors

Check the rotors for grooving or uneven wear. If damaged, they should be replaced.
To replace:
- Remove the rotor by unscrewing any holding screws (if applicable).
- Install the new rotor, ensuring it is clean and free of oil or debris.
- Reattach the caliper over the new rotor.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use the torque wrench to tighten the lug nuts to manufacturer specifications (typically around 90-110 Nm).
Reconnect the battery and test the brakes by gently applying pressure in a safe environment.
