Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working.

2. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, new brake pads.
Remove the wheel by loosening the lug nuts and jacking up the vehicle.
Use a socket set to remove the caliper bolts and carefully slide the caliper off the rotor.
Inspect the brake pads for wear; if they are worn down below the manufacturer’s specifications, replace them.
Clean the caliper and rotor with brake cleaner and install new brake pads, ensuring they are seated properly.
Reattach the caliper and torque the bolts to manufacturer specifications.

3. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, turkey baster, funnel.
Remove the brake fluid reservoir cap and inspect fluid condition; if it is dark or contaminated, it should be replaced.
Use a turkey baster to remove old brake fluid from the reservoir.
Refill the reservoir with fresh brake fluid that meets manufacturer specifications.
Bleed the brakes to remove air from the lines by using a brake bleeder kit, starting from the wheel farthest from the master cylinder.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Socket set, torque wrench, brake cleaner.
If the rotors are found to be warped or scored during inspection, they should be replaced.
Remove the caliper and brake pads as previously described, then remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install new rotors and torque to manufacturer specifications.
