Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Check and Replace Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir under the hood.
2. Remove the cap and inspect the brake fluid level.
3. If the fluid is low, top it off with the appropriate DOT brake fluid (check the owner’s manual for specifications).
4. If the fluid is contaminated or discolored, proceed to flush the brake system.
5. To flush, connect a brake bleeder kit to the brake bleeder valve on each wheel and pump through clean fluid until clear fluid appears.

Tools Required:

Brake bleeder kit
Funnel

3. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect the brake lines for any signs of wear, corrosion, or leaks.
2. If any damaged sections are found, replace the affected brake lines using a pipe cutter and flaring tool.
3. Refill the brake fluid reservoir and bleed the brakes at each wheel to remove air.

Tools Required:

Pipe cutter
Flaring tool
Wrenches

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check rotors for scoring or excessive wear; replace if necessary.
4. Clean or replace any rusted calipers or wheel cylinders.
