Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder reservoir cap.
2. If brake fluid is low, top it off with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
3. If the fluid is contaminated, proceed to flush the brake system.

Tools Required: Brake fluid tester, funnel, safety gloves.

3. Repair or Replace Brake Lines

Sub-steps:
1. If leaks are found, replace damaged brake lines with new lines of appropriate specifications.
2. Use brake line wrenches to avoid stripping fittings during removal.
3. Bleed the brake system after replacement to remove air from the lines.

Tools Required: Brake line wrenches, line cutter, brake fluid, bleeder kit.

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheels to access brake calipers and pads.
2. Inspect brake pads for wear; replace if they are below the manufacturer’s minimum thickness.
3. Check rotors for warping or damage; machine or replace as necessary.

Tools Required: Socket set, torque wrench, brake caliper tool.

5. Check and Replace Brake Booster (if necessary)

Sub-steps:
1. Inspect the brake booster for any signs of damage or vacuum leaks.
2. If faulty, disconnect the brake lines and unbolt the brake booster from the firewall.
3. Install the new brake booster and reconnect all lines and fittings.

Tools Required: Socket set, vacuum gauge.
