Diagnostic Steps

1
Inspect brake pads for wear; measure thickness and check for any damage.
2
Examine brake rotors for scoring, warping, or excessive wear.
3
Check for debris or foreign objects lodged between brake components.
4
Inspect brake calipers for proper operation and any signs of leakage.

Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Existing Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor without disconnecting the brake line.
- Inspect the brake pads for wear; if they are below the minimum thickness (usually 3mm), replace them.
Replace Brake Pads (if necessary):
- Remove old pads and clean the caliper bracket using brake cleaner.
- Install new brake pads ensuring they are oriented correctly.
- Apply brake grease to the backing of the pads to prevent squeaking.

4. Inspect and Replace Brake Rotors

Inspect Existing Rotors:
- Check the surface of the rotor for scoring or warping.
- Measure rotor thickness; if below specifications or if damaged, replace.
Replace Rotors (if necessary):
- Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Clean the hub surface before installing a new rotor.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble and Test

Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (usually around 23-35 Nm).
Reinstall the wheel and tighten lug nuts in a star pattern to the specified torque (usually around 100 Nm).
Lower the vehicle and reconnect the battery.
