Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Lift the Vehicle: Use a jack to lift the front or rear, depending on which brakes are performing poorly. Secure with jack stands.
Remove Wheel: Use a lug wrench to remove the wheel.
Inspect Brake Pads: Check for uneven wear. If thickness is below 1/8 inch, replace.
Remove Caliper: Unbolt the caliper from the bracket using a socket set. Support it with a bungee cord to avoid stressing the brake line.
Replace Pads: Remove old pads and install new ones. Ensure they are properly seated.

3. Inspect and Resurface/Replace Rotors

Check Rotor Condition: Using a dial indicator, measure for warping. If more than 0.002 inches, resurface or replace.
Remove Rotor: Unbolt and remove the rotor from the hub.
Resurface or Replace: If resurfacing, follow the machine shop’s guidelines. If replacing, install the new rotor and torque to manufacturer specifications.

4. Inspect Suspension Components

Visual Inspection: Check for worn bushings, loose bolts, and damaged components.
Replace Worn Parts: If any parts are found to be defective, replace them with OEM or aftermarket parts.

5. Alignment and Balancing

Check Alignment: Take the vehicle to a professional alignment shop.
Balance Wheels: Inspect and balance the wheels if necessary.
