- Check the fluid level against the minimum and maximum indicators.
- If the fluid is low, top it up with the appropriate brake fluid type (DOT 3 or DOT 4).
Tools Required: Brake fluid, funnel.

3. Check Brake Lines and Hoses

Sub-steps:
- Trace the brake lines from the master cylinder to each wheel.
- Look for any signs of corrosion, cracks, or damage.
- Replace any damaged brake lines or hoses using appropriate fittings.
Tools Required: Wrench set, replacement brake lines or hoses.

4. Inspect Brake Calipers

Sub-steps:
- Remove the wheel to access the brake caliper.
- Examine the caliper housing and seals for signs of fluid leakage.
- If leaks are present, replace the caliper or seals as necessary.
Tools Required: Socket set, jack stands, replacement caliper or seal kit.

5. Check Master Cylinder

Sub-steps:
- Locate the master cylinder near the brake fluid reservoir.
- Inspect for leaks around the base and reservoir cap.
- If leaks are found, replace the master cylinder using proper torque specifications for the mounting bolts.
Tools Required: Socket set, torque wrench, replacement master cylinder.

6. Test the Brake System

Sub-steps:
- Reconnect the battery and fill the brake fluid reservoir to the proper level.
- Bleed the brake system to remove any air bubbles.
- Test by pressing the brake pedal to ensure firmness and proper operation.
Tools Required: Brake bleeder kit, brake fluid.
