Diagnostic Steps

1
Inspect the brake pads visually through the wheel spokes for wear indicators.
2
Use an OBD-II scanner to check for any brake-related error codes.
3
Measure the thickness of the brake pads using a caliper to confirm wear.
4
Check the condition of the brake rotors for scoring or warping.
5
Inspect the brake fluid level in the reservoir and check for leaks.

Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- C-clamp or brake caliper tool
- Brake cleaner
- Soft cloth
- Safety glasses and gloves
Sub-steps:
1. Ensure the vehicle is parked on a flat surface and the engine is off.
2. Wear safety glasses and gloves for protection.
3. Loosen the lug nuts slightly while the vehicle is still on the ground.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Wheel

Completely remove the loosened lug nuts and take off the wheel.
Set the wheel aside in a safe location.

4. Remove the Brake Caliper

Locate the caliper bolts and remove them using the appropriate socket.
Gently lift the caliper off the brake rotor. Do not let it hang by the brake line; use a bungee cord to secure it to the suspension.

5. Replace the Brake Pads

Remove the old brake pads by sliding them out of the caliper bracket.
Inspect the caliper bracket and clean it with brake cleaner.
Install the new brake pads into the caliper bracket, ensuring they are seated properly.
Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing to accommodate the new pads.

6. Reinstall the Brake Caliper

Position the caliper over the new pads and align it with the bracket.
Tighten the caliper bolts to the manufacturer's specified torque (typically around 25-30 Nm for BMWs, but refer to the service manual for exact values).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then tighten the lug nuts to the manufacturer’s specifications using a torque wrench.

8. Final Checks

Pump the brake pedal several times to ensure proper seating of the brake pads.
Check the brake fluid level and top off if necessary.
