Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Jack stands, lug wrench, socket set, brake fluid, torque wrench, brake cleaner, OBD-II scanner.
Safety Warnings: Always wear protective gear, and ensure the vehicle is securely lifted before working underneath.

2. Check and Replace Brake Fluid

Open the hood and locate the master cylinder.
If the fluid is low, top it up with the manufacturer-recommended brake fluid.
If the fluid is dark or contaminated, perform a brake fluid flush.

3. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench.
Use a socket set to remove the caliper bolts and take off the caliper.
Inspect the brake pads for thickness; replace if they are worn down below the minimum thickness (usually 3mm).
Install new brake pads, ensuring they are properly seated.

4. Check and Resurface or Replace Rotors

Inspect the rotors for any signs of warping or excessive wear. If they are warped, they may need to be resurfaced or replaced.
If resurfacing, ensure the rotor thickness is within the manufacturer's specifications.
Install the rotors back onto the hub and torque the bolts to the specified values.

5. Test Brake Booster

Start the engine and press the brake pedal. If the pedal feels hard, the brake booster may be malfunctioning.
Check the vacuum line for cracks or disconnections and replace if necessary.
