Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Repair Brake Fluid

Sub-steps:
1. Check the brake fluid reservoir; if low, top up with the recommended DOT fluid.
2. If the fluid is contaminated (indicated by moisture), drain and replace the entire brake fluid.
Tools Required: Brake fluid, funnel

3. Check for Leaks

Sub-steps:
1. Inspect all brake lines, calipers, and the master cylinder for any signs of leaks.
2. If leaks are found, replace the damaged components (e.g., hoses, calipers).
Tools Required: Wrench set, socket set

4. Bleed the Brake System

Sub-steps:
1. Start from the brake furthest from the master cylinder (usually the rear passenger side).
2. Attach a clear hose to the bleeder valve of the brake caliper and submerge the other end in a container with brake fluid.
3. Have an assistant pump the brake pedal several times, holding it down on the last pump.
4. Open the bleeder valve to release air and fluid; close the valve before the assistant releases the pedal.
5. Repeat until no air bubbles are seen in the fluid flowing through the hose.
6. Move to the next brake in the sequence (rear driver side, front passenger side, front driver side).
Tools Required: Brake bleeder kit, clear hose, wrench

5. Inspect Brake Components

Sub-steps:
1. Remove the wheels and inspect brake pads for wear; replace if thickness is below the manufacturer’s specification.
2. Inspect rotors for warping or grooves; resurface or replace as necessary.
Tools Required: Jack and jack stands, lug wrench, caliper tool
