Solution

1. Preparation

Gather necessary tools: clean rag, funnel, and new brake fluid.
Ensure the vehicle is on level ground and the engine is off.

2. Assess Fluid Level

Check Reservoir: Look at the brake fluid reservoir to see if the fluid is at or below the minimum line.
Clean the Area: Wipe the cap and surrounding area with a clean rag to prevent contamination when opening.

3. Add Brake Fluid

Open Reservoir Cap: Carefully remove the reservoir cap without spilling any fluid.
Add Fluid: Using a funnel, add the appropriate type of brake fluid (typically DOT 3 or DOT 4, refer to the owner's manual).
Do Not Overfill: Fill only to the maximum line; avoid overfilling as it may cause fluid to overflow when brakes are applied.

4. Reassemble

Replace Cap Securely: Ensure the reservoir cap is tightly closed to prevent moisture contamination.
Clean Up: Wipe any spills immediately to prevent damage to paint and surfaces.

5. Test the Brakes

Pump the Brake Pedal: Press the brake pedal several times to ensure it feels firm.
Check for Leaks: Inspect the area around the brake components for any signs of leaks after adding fluid.
