⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety gloves and goggles when working on the braking system.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Brake pedal feels spongy or goes to the floor with little resistance.
•Brake warning light illuminated on the dashboard.
•Reduced stopping power or longer stopping distances.
•Fluid leakage under the vehicle, particularly near the wheels or master cylinder.
•Unusual noises (squealing or grinding) when applying brakes.

Diagnostic Steps

1
Check the brake fluid level in the master cylinder reservoir.
2
Inspect for any visible leaks in brake lines, hoses, and around the master cylinder.
3
Scan the vehicle for any diagnostic trouble codes (DTCs) using an OBD-II scanner.
4
Test the brake booster functionality by applying pressure to the brake pedal while the engine is off, then starting the engine to see if the pedal drops slightly.
5
Inspect the brake pads and rotors for wear or damage.
6
Look for signs of air in the brake lines by performing a brake pedal pump test.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear safety gloves and glasses for protection.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth.
Inspect the master cylinder reservoir and determine if the fluid is low.
If low, clean the reservoir cap and add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Close the cap securely after filling.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit (if applicable).
Visually inspect all brake lines and hoses for cracks or leaks.
If any leaks are found, replace damaged brake lines or hoses.
Tighten any loose connections, especially at the master cylinder and calipers.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, container.
Start at the wheel furthest from the master cylinder (right rear, left rear, right front, left front).
Attach the tubing to the bleeder screw and submerge the other end in the container filled with brake fluid.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder screw to release air and fluid, then close it before the pedal is released.
Repeat until no air bubbles are present, then move to the next wheel.

5. Inspect and Replace Brake Components (if necessary)

Tools Required: Socket set, torque wrench, brake pads/rotors (if needed).
If brake pads or rotors are worn or damaged, remove the wheel and use a socket set to remove the caliper and bracket.
Replace the pads and/or rotors as needed, ensuring to torque all bolts to manufacturer specifications.
