Diagnostic Steps

1
Inspect brake pads visually for uneven wear patterns.
2
Measure the thickness of each brake pad using a caliper.
3
Check brake rotor condition for warping or scoring.
4
Examine caliper function and alignment for sticking or binding.
5
Inspect suspension components (e.g., bushings, control arms) for wear or damage.
6
Assess brake fluid level and condition, ensuring it is clean and at the proper level.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, torque wrench, socket set, brake cleaner, and safety glasses.
Safety Warnings: Ensure the vehicle is on a flat surface. Use jack stands to support the vehicle securely after lifting.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Pads:
- Use a caliper gauge to measure the thickness of each brake pad. Note any significant differences.
Replace Pads:
- If uneven wear is significant, remove the caliper bolts with a socket set and slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease on the contact points of the new pads.
- Install new brake pads, ensuring they are seated correctly in the bracket.
Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer's specifications.

4. Check and Replace Brake Rotors (if necessary)

Inspect the brake rotors for signs of warping or scoring.
If replacement is required, remove the caliper and brake pads as previously described.
Remove the rotor by unscrewing the retaining screws (if equipped) and pulling the rotor off the hub.
Install the new rotor and reassemble the brake components in reverse order.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
Press the brake pedal several times to seat the new pads and ensure proper contact with the rotors.
