Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, brake caliper tool, torque wrench.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if below manufacturer's specifications.
To replace, remove the caliper bolts using a socket set, then slide off the caliper.
Replace old pads with new ones, ensuring they are correctly aligned.
Reattach the caliper and torque bolts to manufacturer specifications.

3. Inspect and Replace Brake Rotors

Tools Required: Rotor puller (if needed), torque wrench.
While the caliper is removed, inspect the rotors for warping or excessive wear.
If replacement is needed, remove the rotor by unscrewing any retaining screws or using a rotor puller if necessary.
Install new rotors by aligning them properly and securing them with screws.
Ensure to clean the surface of the rotor with brake cleaner to remove any protective coating.

4. Brake Fluid Check and Replacement

Tools Required: Brake fluid, funnel, turkey baster.
Check the brake fluid reservoir for level; top up if necessary.
If the fluid is contaminated or has absorbed moisture, perform a brake fluid flush.
Remove the old fluid using a turkey baster and replace it with new fluid, ensuring it meets manufacturer specifications.

5. Suspension Inspection and Repair

Tools Required: Jack and jack stands, socket set.
Raise the vehicle using a jack and secure with jack stands.
Inspect the struts, shock absorbers, and control arm bushings for visible wear or damage.
Replace any worn components with new parts, ensuring proper alignment and torque specifications are followed.
