Diagnostic Steps

2
Check the owner's manual for recommended brake fluid change intervals.
3
Use a brake fluid tester to measure moisture content in the fluid.

Solution

1. Preparation

Gather Tools: Brake fluid tester, clean cloths, funnel, new brake fluid (DOT 4 recommended), and safety goggles.
Safety Warning: Ensure the vehicle is parked on a level surface and the engine is off. Wear gloves and goggles to protect against brake fluid.

2. Inspect Fluid Condition

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent contamination.
Remove the cap and visually inspect the fluid for clarity and color. If it appears dark or contaminated, it should be replaced.

3. Check Fluid Level

Ensure the brake fluid level is between the minimum and maximum markings on the reservoir.
If the level is low, top it up with new brake fluid before proceeding to a full change.

4. Change Brake Fluid

Drain Old Fluid:
- Begin by using a brake bleeder kit or a turkey baster to remove old fluid from the reservoir.
- Dispose of the old fluid according to local regulations.
Refill with New Fluid:
- Use a funnel to pour new brake fluid into the reservoir until it reaches the maximum mark.
Bleed the Brakes:
- Start with the wheel farthest from the master cylinder (usually the rear passenger side).
- Attach a hose to the bleeder valve on the brake caliper.
- Have an assistant pump the brake pedal several times and hold it down.
- Open the bleeder valve to let out old fluid and air bubbles, then close it before your assistant releases the pedal.
- Repeat until clear fluid flows from the bleeder valve, then move to the next wheel in order (rear driver side, front passenger side, front driver side).

5. Final Checks

Recheck the brake fluid level in the reservoir and adjust if necessary.
Replace the reservoir cap securely.
Dispose of old brake fluid properly.
