Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gear such as gloves and goggles.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir on the driver's side of the engine bay.
Remove the cap and check the fluid level; add DOT 3 or DOT 4 brake fluid as necessary to reach the recommended level.
Replace the cap securely.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, clear tubing, wrench.
Begin with the wheel farthest from the master cylinder, typically the passenger rear.
Attach the clear tubing to the bleeder valve on the brake caliper.
Use a wrench to open the bleeder valve slightly and have an assistant press the brake pedal slowly.
Close the bleeder valve before your assistant releases the brake pedal.
Repeat this process until the fluid runs clear and free of air bubbles.
Move to the next wheel (driver rear, passenger front, driver front) and repeat.

4. Inspect and Replace Brake Components (if necessary)

If soft pedal persists after bleeding, inspect brake pads and rotors.
Remove the wheel and caliper.
Check brake pads for wear; replace if less than 3mm thick.
Inspect rotors for scoring or damage; replace if necessary.
Reassemble components and torque bolts to manufacturer specifications.
