Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Wear safety glasses and gloves.

2. Inspect Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; if low, top off with the manufacturer's recommended brake fluid type.

3. Bleed the Brakes

Tools Required: Brake bleeder kit or clear tubing, container for old brake fluid.
Start with the brake furthest from the master cylinder (usually the passenger side rear).
Attach the clear tubing 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 allow air and fluid to escape, then close it before the assistant releases the pedal.
Repeat this process until no air bubbles are seen in the fluid and the pedal feels firm.
Move to the next brake in the sequence: driver side rear, passenger side front, and finally driver side front.

4. Inspect Brake Components

Visually inspect brake pads and calipers to ensure they are properly seated.
Check that the caliper pistons are retracted fully and that there are no obstructions.

5. Check Master Cylinder

If the brake pedal remains soft, it may indicate a faulty master cylinder.
Remove the master cylinder from the brake booster and inspect for internal leaks or damage.
Replace the master cylinder if necessary.
