Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Check and Top Off Brake Fluid

Locate the brake master cylinder reservoir.
Inspect the brake fluid level; if low, add the recommended DOT brake fluid (usually DOT 3 or DOT 4).
If the fluid is dirty or contaminated, proceed to replace it.

3. Inspect Brake Lines and Components

Visually inspect brake lines for any signs of wear, corrosion, or leaks.
Tighten any loose brake line fittings.
Replace any damaged brake lines with OEM or quality aftermarket parts.

4. Replace Brake Pads and Rotors (if needed)

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.
Unbolt the brake caliper and hang it securely without stressing the brake line.
Remove the old brake pads and inspect the rotors for scoring or warping.
Replace worn brake pads and rotors as necessary; ensure to use proper torque when reassembling.

5. Bleed the Brake System

Start at the wheel furthest from the master cylinder (usually the right rear).
Attach a clear hose to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and then hold it down.
Open the bleeder valve to allow air and old fluid to escape; close the valve and repeat until no air bubbles appear.
Repeat for each wheel in the following order: right rear, left rear, right front, left front.
Check the brake fluid level and top off as needed.
