Diagnostic Steps

1
Inspect brake pads for wear and proper installation.
2
Check brake rotors for warping or damage using a runout gauge.
3
Examine the brake calipers for proper operation and alignment.
4
Inspect wheel bearings for play or damage.
5
Check tire condition and balance.
6

Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, wheel chocks, brake cleaner.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery (if necessary) to prevent electrical issues.

2. Inspect and Replace Brake Pads

Remove Wheel:
- Loosen lug nuts and lift the vehicle with a jack.
- Secure with jack stands and remove the wheel.
Inspect Brake Pads:
- Examine for uneven wear or thickness below specifications (usually below 3mm).
- If worn, remove caliper bolts and slide the caliper off the rotor.
Install New Brake Pads:
- Clean caliper bracket and ensure the new pads are compatible.
- Apply brake grease to the backing of the new pads to reduce noise.
- Reinstall caliper over the new pads and torque bolts to manufacturer specifications (typically 20-30 Nm).

3. Inspect and Replace Brake Rotors

Check Rotor Condition:
- Measure rotor thickness with a micrometer and check for warping using a runout gauge.
- If warped or below minimum thickness, proceed to replace.
Remove Old Rotors:
- Remove caliper and caliper bracket.
- Unscrew rotor retaining screws (if equipped) and slide the rotor off the hub.
Install New Rotors:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Place the new rotor on the hub and secure with retaining screws.

4. Brake System Bleed

Bleed Brakes:
- Reconnect the brake line if disconnected.
- Use a brake bleeder kit to remove air from the system, starting from the wheel farthest from the master cylinder.
- Ensure fluid levels are maintained in the master cylinder throughout the process.
