Symptoms

•Spongy or soft brake pedal feel
•Extended stopping distance
•Brake warning light illuminated on the dashboard
•Brake fluid leak under the vehicle
•Unusual noises from the braking system (squealing or grinding)

Diagnostic Steps

1
Inspect brake fluid level in the reservoir; ensure it is within the recommended range.
2
Check for visible brake fluid leaks around brake lines, calipers, and the master cylinder.
3
Inspect brake pads and rotors for wear; measure thickness and check for glazing or damage.
4
Examine brake lines for any signs of corrosion or damage.
5
Test the brake master cylinder for internal leaks by pumping the brake pedal and observing if it sinks gradually.
6
Bleed the brake system to remove any air trapped in the lines.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; if low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
3. Replace the cap securely.

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads and rotors; replace if worn below minimum thickness (usually 3mm for pads).
3. Check for any damage or warping on the rotors; replace if necessary.
4. Inspect the calipers for proper operation and ensure they are not sticking.

4. Bleed the Brake System

Sub-steps:
1. Begin at the wheel farthest from the master cylinder (usually the right rear).
2. Use a brake bleeder kit or a helper to pump the brake pedal while you open the bleeder valve on the caliper.
3. Allow old fluid and air to escape until clear fluid is seen, then close the valve before releasing the brake pedal.
4. Repeat for each wheel in the correct order (right rear, left rear, right front, left front).
5. Recheck the brake fluid level and top off as needed.
