Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Damaged Brake Lines

Tools Required: Wrench set, brake line cutter, flare tool.
Visually inspect all brake lines for corrosion or damage.
If damaged, use the brake line cutter to remove the affected section.
Use the flare tool to create new flares on the replacement line.
Install the new line and secure it with appropriate fittings.

3. Replace Worn Brake Components

Tools Required: Socket set, torque wrench, brake cleaner.
Remove the wheel to access the brake components.
Inspect calipers and wheel cylinders for leaks; replace if necessary.
Use brake cleaner to clean any residue from the old components.
Install new calipers or wheel cylinders and torque to manufacturer's specifications.

4. Replace Master Cylinder (if necessary)

Tools Required: Wrench set, brake fluid funnel, torque wrench.
Disconnect the negative battery cable.
Remove the master cylinder by loosening the mounting bolts.
Carefully disconnect the brake lines and cap them to prevent fluid loss.
Install the new master cylinder and reconnect brake lines.
Torque the bolts to the specified value (refer to the service manual).

5. Refill Brake Fluid and Bleed System

Tools Required: Brake fluid (DOT 3 or 4 as specified), brake bleeder kit.
Refill the brake fluid reservoir with new fluid.
Use a brake bleeder kit to bleed each brake caliper, starting from the furthest from the master cylinder.
Check for air bubbles and ensure the pedal feels firm.
