⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses and gloves when working on the braking system.
•Allow the vehicle to cool before working on components that may be hot.

Symptoms

•Brake pedal feels spongy or soft when pressed
•Increased stopping distance
•Brake warning light illuminated on the dashboard
•Unusual noises during braking (e.g., grinding or squeaking)
•Fluid leaks under the vehicle near the wheels or under the master cylinder

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for visible leaks in brake lines, hoses, and at the wheel calipers.
3
Use an OBD-II scanner to check for any ABS or brake-related error codes.
4
Test the brake booster for proper operation by pumping the brake pedal with the engine off and then starting the engine to see if the pedal drops slightly.
5
Inspect brake pads and rotors for wear or damage.
6
Bleed the brake system to check for air in the lines.

Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, turkey baster.
Remove the cap from the brake fluid reservoir.
Use a turkey baster to siphon out old brake fluid.
Refill the reservoir with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Check and Repair Brake Lines

Tools Required: Wrench set, brake line replacement kit (if necessary).
Inspect all brake lines for corrosion or leaks.
If leaks are found, replace the damaged sections of brake line.
Torque any fittings to manufacturer specifications.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or hose, catch container.
Locate the brake bleeder valves on each brake caliper (starting with the wheel farthest from the master cylinder).
Attach the bleeder hose to the valve and place the other end in a catch container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release fluid and air, then close it before the pedal is released.
Repeat until clear brake fluid is flowing without bubbles, then move to the next caliper.
Ensure the master cylinder does not run low on fluid during bleeding.

5. Inspect Brake Components

Tools Required: Jack, jack stands, lug wrench.
Lift the vehicle and remove the wheel to access brake components.
Inspect brake pads for thickness (should be at least 3mm) and replace them if worn.
Check rotors for scoring or warping and replace if necessary.
