•Possible noise during braking (grinding or squeaking)

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a run-out gauge.
2
Check brake pads for wear, ensuring they have sufficient thickness.
3
Examine suspension components (tie rods, ball joints, control arms) for play or damage.
4
Verify wheel alignment and balance to rule out related issues.
5
Inspect brake calipers for proper operation and check for any sticking.

Diagnostic Steps

1

2
Check brake pads for wear, ensuring they have sufficient thickness.

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure electrical safety.

2. Remove Wheel

Tools required: Socket set, lug wrench.
Loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors

Check the rotors for warping using a run-out gauge.
If warped beyond tolerance (usually 0.002 inches), proceed to replace.
Remove the caliper by unbolting it from the bracket (use a torque wrench for reinstallation).
Remove the rotor; if it is stuck, gently tap it to loosen.
Install the new rotor and torque the mounting bolts to manufacturer specifications (typically around 80-100 lb-ft).

4. Replace Brake Pads

Tools required: Brake pad spreader tool, torque wrench.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly.
Apply anti-squeal lubricant to the back of the pads for noise reduction.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle, then torque the lug nuts in a crisscross pattern to the manufacturer's specifications (typically 80-100 lb-ft).
Reconnect the battery.
