Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical issues.

2. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Inspect the brake fluid level; if low, fill it with the recommended brake fluid type (usually DOT 3 or DOT 4).
If the fluid is dirty or contaminated, drain the system by removing the brake fluid reservoir cap and using a turkey baster to remove old fluid. Refill with fresh brake fluid.

3. Inspect and Replace Brake Pads and Rotors

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, new brake pads, new rotors.
Lift the vehicle and remove the wheel to access the brake assembly.
Remove the caliper bolts and slide the caliper off the rotor. Hang the caliper securely without putting stress on the brake line.
Remove the old brake pads from the caliper bracket.
Measure the thickness of the rotors; if below the manufacturer's minimum specification, replace them.
Clean the rotor surface with brake cleaner and install new rotors if necessary.
Install new brake pads, ensuring they are correctly oriented.
Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Hoses (if necessary)

Tools Required: Wrench set, brake line wrench, new brake hoses.
Inspect brake hoses for any signs of wear or leaks. Replace if damaged.
To replace, remove the old hose by loosening the fittings and carefully detach it from the caliper and brake line.
Install the new hose, ensuring all fittings are tightened securely.

5. Test Brake Booster (if applicable)

Tools Required: Vacuum gauge (if available).
With the engine running, check the brake booster operation by pressing the brake pedal; it should feel firm.
If the pedal feels hard, the booster may need replacing.
