Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety glasses and gloves.

2. Check Brake Fluid Level

Open the hood and locate the master cylinder.
Inspect the brake fluid level; if low, fill with the appropriate DOT fluid as specified in the owner’s manual.
Tools Required: Brake fluid, funnel

3. Inspect for Leaks

Visually inspect all brake lines, calipers, and wheel cylinders for any signs of fluid leaks.
If a leak is found, replace the damaged component (e.g., brake line, caliper).
Tools Required: Wrench set, replacement parts as necessary

4. Bleed the Brake System

Start with the brake furthest from the master cylinder (usually the right rear).
Attach a clear hose to the bleeder screw, and submerge the end in a container with brake fluid.
Have an assistant pump the brake pedal several times, then hold it down while you open the bleeder screw to allow air and fluid to escape. Close the screw before releasing the pedal.
Repeat this process for each brake, moving from the rear to the front.
Tools Required: Brake bleeder kit, wrench for bleeder screws

5. Inspect and Replace Brake Pads and Rotors (if necessary)

Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn down below specifications (usually 3mm).
Check the rotors for scoring or warping; replace if necessary.
Reassemble the brakes and wheel.
Tools Required: Jack and jack stands, socket set, torque wrench

6. Check Brake Booster

Inspect the brake booster for vacuum leaks by listening for hissing sounds.
If defective, replace the brake booster.
Tools Required: Replacement brake booster, socket set
