Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, torque wrench, jack, jack stands, brake cleaner.
Remove the wheel on the affected side.
Inspect the brake pads for wear; replace if they are below the minimum thickness.
Check the rotor for scoring or warping; replace if damaged.
Clean the rotor surface with brake cleaner before installation.

3. Check and Clean Brake Calipers

Inspect the caliper for proper movement and ensure the piston is not seized.
If the caliper is sticking, it may need to be rebuilt or replaced.
Clean the caliper slides and apply brake grease to ensure smooth movement.

4. Perform Wheel Alignment

Tools Required: Alignment machine (usually requires professional service).
After replacing brake components, take the vehicle to a professional alignment shop.
Ensure that the toe, camber, and caster are within manufacturer specifications.

5. Inspect Suspension Components

Check tie rods, control arms, and bushings for signs of wear.
Replace any worn or damaged components to ensure proper steering and suspension function.
