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 electrical issues.

2. Inspect and Replace Brake Booster

Tools Required: Wrench set, vacuum gauge, brake booster replacement (if necessary).
Remove the vacuum hose connected to the brake booster. Check for cracks or leaks.
Use a vacuum gauge to test the brake booster; a reading below 18 inches of mercury indicates a problem.
If defective, unbolt the brake booster from the firewall and disconnect the pushrod from the brake pedal.
Install the new brake booster by reversing the removal steps, ensuring all connections are secure.

3. Check and Replace Master Cylinder

Tools Required: Wrench set, brake fluid, master cylinder replacement (if necessary).
Inspect the master cylinder for leaks, and if any are found, proceed with replacement.
Disconnect the brake lines from the master cylinder and remove any retaining bolts.
Install the new master cylinder by reversing the removal steps, ensuring lines are tightened to manufacturer specifications (typically 12-15 ft-lbs).

4. Brake Fluid Replacement

Tools Required: Brake fluid, bleeder kit.
After installing the new components, refill the brake fluid reservoir with the appropriate DOT fluid.
Bleed the brake lines starting from the furthest wheel from the master cylinder to ensure all air is purged from the system.
