Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial gauge.
2
Check brake pads for uneven wear or contamination.
3
Verify caliper operation by inspecting for sticking or binding.
4
Assess suspension components, including control arms and bushings for wear.
5
Examine wheel alignment and tire condition for uneven wear or damage.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Wear safety gloves and glasses.

2. Remove Wheels

Use a jack to lift the vehicle and secure it with jack stands.
Remove lug nuts using a socket wrench and take off the wheels.

3. Inspect and Replace Brake Components

3.1. Inspect Brake Rotors

Check rotors with a dial gauge for warping.
If warped, replace with new rotors. Torque new rotors to manufacturer specifications (typically around 80-100 ft-lbs).

3.2. Replace Brake Pads

Remove caliper bolts and carefully lift the caliper off the rotor.
Remove old brake pads and clean the caliper bracket.
Install new brake pads, ensuring they are properly seated.

3.3. Inspect and Replace Calipers (if necessary)

If calipers are found to be sticking, replace them.
Ensure new calipers are bled properly to remove air from the brake lines.

4. Reassemble Components

Reattach the caliper and secure it with bolts.
Reinstall the wheels and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle from the jack stands.
Torque the lug nuts to the specified value (usually around 100-120 ft-lbs).
