Symptoms

•Brake pedal sinks to the floor with little resistance
•Increased stopping distance
•Brake warning light illuminated on the dashboard
•Uneven braking or pulling to one side
•Possible fluid leak under the vehicle

Diagnostic Steps

1
Inspect the brake fluid level in the master cylinder reservoir.
2
Check for visible brake fluid leaks around brake lines, calipers, and wheel cylinders.
3
Test the brake booster for proper operation by pumping the brake pedal with the engine off, then starting the engine and observing if the pedal sinks slightly.
4
Scan the vehicle for any fault codes related to the brake system using an OBD-II scanner.
5
Inspect brake pads and rotors for wear and damage.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Locate the brake master cylinder reservoir.
Remove the cap and check the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect and Replace Brake Lines (if leaking)

Inspect all brake lines for signs of wear or leaks.
If leaks are found, carefully disconnect the affected brake line using a wrench.
Replace with a new brake line, ensuring it is securely fastened and properly bled to remove air.
Use a flare wrench to prevent damage to the brake line fittings.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually the passenger rear).
Use a brake bleeder kit or a helper to press the brake pedal while you open the bleeder valve on the brake caliper.
Close the valve before the pedal reaches the floor and repeat until no air bubbles are visible in the fluid.
Repeat for each wheel in the correct sequence (passenger rear, driver rear, passenger front, driver front).

5. Replace Brake Pads and Rotors (if worn)

Remove the wheel and tire to access the brake assembly.
Remove caliper bolts and slide the caliper off the rotor.
Replace old brake pads with new ones; ensure they are properly seated.
Inspect the rotor for wear; if warped or excessively worn, replace with a new rotor.
Reinstall the caliper and wheel, ensuring all components are tightened to the manufacturer's torque specifications.
