Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow brake components to cool before handling.

Symptoms

•Brake pedal feels soft or spongy when pressed
•Increased stopping distance
•Brake warning light illuminated on the dashboard
•Fluid leaks around brake components
•Brake system making unusual noises (e.g., grinding or squealing)
•Reduced braking effectiveness

Diagnostic Steps

1
Inspect the brake fluid level in the reservoir and check for leaks in the brake lines and around the master cylinder.
2
Check the condition of the brake pads and rotors for wear or damage.
3
Look for air in the brake lines by performing a brake fluid pressure test.
4
Inspect the brake master cylinder for signs of failure or internal leaks.
5
Examine the brake booster for proper function and any vacuum leaks.

Solution

Solution

1. Preparation

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

2. Check Brake Fluid and Lines

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; if low, refill with the recommended brake fluid (DOT 3 or DOT 4).
- Inspect brake lines and connections for leaks; replace any damaged lines.

3. Bleed the Brake System

Sub-steps:
- Start with the wheel farthest from the master cylinder (usually the right rear).
- Use a brake bleeder kit or a clear hose attached to the bleeder valve.
- Have an assistant press the brake pedal while you open the bleeder valve to release air and fluid until a steady stream of fluid is observed.
- Tighten the bleeder valve before the assistant releases the brake pedal.
- Repeat for the left rear, right front, and left front brakes in that order.

4. Inspect and Replace Brake Components

Sub-steps:
- Remove the wheel to access the brake caliper and rotor.
- Inspect brake pads for thickness; replace if worn below the manufacturer's specification.
- Check rotors for warping or damage; resurface or replace as necessary.
- Reassemble all components, ensuring proper torque specifications for lug nuts and caliper bolts.

5. Test Drive and Final Inspection

Sub-steps:
- After completing repairs, test drive the vehicle in a safe area to ensure brakes are functioning correctly.
- Recheck brake fluid level and inspect for leaks once again after the test drive.
