Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; if low, refill with the appropriate type of brake fluid (typically DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect for Leaks

Tools Required: Flashlight
Visually inspect brake lines, calipers, and wheel cylinders for any signs of fluid leaks.
If leaks are detected, replace the damaged components (e.g., lines, calipers).

4. Replace Worn Brake Pads and Rotors

Tools Required: Socket set, torque wrench, brake pad spreader
Remove the wheel to access the brake assembly.
Remove the caliper bolts and carefully slide off the caliper.
Remove old brake pads and inspect the rotors for wear.
If rotors are damaged, replace them. Install new brake pads and reassemble the caliper.
Torque caliper bolts to manufacturer specifications.
