Solution

1. Preparation

Gather necessary tools and equipment.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Remove the brake fluid reservoir cap.
Check the fluid level; if it’s below the minimum line, add the appropriate brake fluid (usually DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the reservoir cap securely.

3. Brake Pad and Rotor Replacement (if needed)

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench
Loosen the lug nuts on the wheels and raise the vehicle using a jack. Secure with jack stands.
Remove the wheels.
Remove the caliper bolts using a socket wrench, then carefully slide the caliper off the rotor.
Inspect the brake pads for thickness; if below 1/8 inch, replace them.
Remove the old pads and install new ones in the caliper bracket.
Reinstall the caliper and torque the bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reassemble the wheel and lower the vehicle.

4. Brake Line Inspection and Repair (if necessary)

Inspect brake lines for any cracks, corrosion, or leaks.
If a leak is found, replace the affected brake line using a line wrench to prevent rounding the fittings.
Bleed the brake system to remove any air trapped in the lines after replacement.

5. Master Cylinder Replacement (if necessary)

Tools Required: Brake line wrench, socket set, torque wrench
Disconnect the negative battery terminal.
Remove brake line connections from the master cylinder.
Unbolt the master cylinder from the brake booster and replace it with a new unit.
Reconnect brake lines and bleed the system to remove air.
