Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Brake Pedal Assembly

Remove the lower dash panel to access the brake pedal assembly.
Inspect for any obstructions that may be causing the pedal to stick.
Clean the pivot points using a lubricant like WD-40 or lithium grease.

3. Check and Replace Brake Fluid

Locate the brake master cylinder and remove the cap.
Use a turkey baster to remove old brake fluid.
Refill with fresh brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
Bleed the brake lines if necessary to remove air from the system.

4. Inspect Brake Booster

Disconnect the vacuum hose from the brake booster.
Check for any cracks or damage to the booster.
If faulty, replace the brake booster with a new unit, following the manufacturer’s specifications.

5. Inspect and Replace Master Cylinder (if necessary)

Remove the brake lines from the master cylinder using a line wrench.
Unbolt the master cylinder from the brake booster and remove it from the vehicle.
Replace it with a new master cylinder and torque the bolts to manufacturer specifications (typically around 15-20 ft-lbs).
Reconnect the brake lines and bleed the system to remove air.

6. Final Assembly

Reinstall the lower dash panel.
Reconnect the negative battery terminal.
Test the brake pedal operation by pressing down and ensuring it returns to its resting position.
