Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Wear safety goggles and gloves for protection.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Locate the brake fluid reservoir under the hood.
Check the fluid level; if it is low, refill it to the appropriate level with the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
Inspect for any visible leaks around the reservoir, brake lines, and calipers.

3. Replace Worn Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set, brake pad replacement kit
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake caliper.
Use the socket set to remove the caliper bolts and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket and replace them with new ones, ensuring correct orientation.
Reattach the caliper and wheel, then lower the vehicle.

4. Check and Replace the Brake Master Cylinder (if necessary)

Tools Required: Brake line wrench, new master cylinder, brake fluid
Disconnect the battery to avoid electrical shorts.
Use a brake line wrench to carefully disconnect the brake lines from the master cylinder.
Remove the mounting bolts securing the master cylinder to the brake booster and remove it.
Install the new master cylinder in reverse order, making sure to bleed the brakes afterward to remove any air from the lines.

5. Inspect and Replace Brake Warning Switch (if necessary)

Tools Required: Multimeter, replacement brake warning switch
Locate the brake warning switch near the brake pedal assembly.
Use a multimeter to test the switch for continuity.
If faulty, disconnect the wiring harness and remove the switch.
Install the new switch, reconnect the wiring, and test for proper operation.
