Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, gloves
Check the brake fluid level; if low, refill with the appropriate brake fluid type as specified in the owner's manual.
If the fluid appears dirty or contaminated, proceed to replace it:
- Use a brake bleeder kit to remove old fluid from the system.
- Refill the master cylinder with fresh brake fluid.

3. Brake Line and Component Inspection

Tools Required: Wrench set, pliers, brake line wrench
Inspect all brake lines for signs of wear, corrosion, or leaks.
Tighten any loose fittings and replace any damaged lines.
Check the brake calipers for leaks or sticking; replace if necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or a helper, clear tubing, container
Attach the clear tubing to the bleeder valve on the caliper.
Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
Close the valve before the pedal is released to prevent air from re-entering the system.
Repeat this process on each wheel until the fluid runs clear and free of air bubbles.

5. Reassemble and Test

Reconnect the battery and ensure everything is secure.
Test the brake pedal feel by pressing it several times before driving.
Conduct a test drive to verify proper braking function.
