Solution

1. Preparation

Park the vehicle on a flat surface and set the parking brake.
Gather tools and parts required for the repair.
Wear appropriate safety gear (gloves and goggles).

2. Inspect and Repair Brake Lines

Sub-step 1: Visually inspect all brake lines for corrosion, wear, or leaks.
Sub-step 2: If leaks are found, replace damaged sections of the brake line.
Tools Required: Wrenches, brake line flaring tool (if needed).

3. Replace Brake Fluid

Sub-step 1: Remove the master cylinder cap and check for contamination in the brake fluid.
Sub-step 2: Use a brake bleeder kit to flush the old brake fluid and replace it with new, manufacturer-recommended fluid.
Tools Required: Brake bleeder kit, turkey baster, new brake fluid.

4. Bleed Brake System

Sub-step 1: Begin bleeding at the farthest wheel from the master cylinder, typically the rear right.
Sub-step 2: Have an assistant pump the brake pedal and hold it down while you open the bleeder valve to release air.
Sub-step 3: Close the bleeder valve and repeat until all air is removed; check fluid levels frequently.
Sub-step 4: Repeat for all wheels in the correct order (rear right, rear left, front right, front left).
Tools Required: Brake bleeder wrench, clear hose.

5. Inspect Brake Pads and Rotors

Sub-step 1: Remove the wheels and inspect the brake pads for thickness; replace if below manufacturer specifications.
Sub-step 2: Check the rotors for scoring or warping; replace if necessary.
Tools Required: Socket set, torque wrench.
