⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported before working on brakes.
•Always wear safety glasses and gloves when handling brake fluid, as it can damage paint and skin.

Symptoms

•Soft or spongy brake pedal feel
•Longer stopping distance
•Brake warning light illuminated
•Unusual noises (squeaking or grinding) when braking
•Brake fluid leakage under the vehicle
•Increased travel of the brake pedal before engaging brakes

Diagnostic Steps

1
Inspect brake fluid level in the master cylinder reservoir.
2
Check for any visible leaks in the brake lines or at the calipers.
3
Examine the brake pads for wear and the condition of the rotors.
4
Test the brake booster for proper operation by pressing the pedal while the engine is off, then starting the engine to see if the pedal drops slightly.
5
Scan for any diagnostic trouble codes (DTCs) using an OBD-II scanner.
6
Bleed the brake system to check for air in the brake lines.

Solution

1. Preparation

Gather tools and materials: socket set, brake bleeder kit, brake fluid (DOT 3 or DOT 4), and safety glasses.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves for protection.

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder reservoir.
Inspect the fluid level; if low, add the appropriate brake fluid until it reaches the full mark.
If the fluid is dirty or contaminated, consider a brake fluid flush.

3. Inspect and Replace Brake Components

Inspect Brake Lines and Calipers:
- Visually check all brake lines for signs of wear, corrosion, or leaks.
- Inspect brake calipers for leaks or damage. Replace any faulty components.
Check Brake Pads and Rotors:
- Remove the wheel to access the brake assembly.
- Measure the thickness of the brake pads; replace if worn below specifications (usually 3mm).
- Inspect rotors for warping or excessive wear; replace if necessary.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (usually right rear).
Attach the brake bleeder kit.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and fluid, then close the valve before the assistant releases the pedal.
Repeat until no air bubbles are present in the fluid.
Move to the next wheel and repeat the process (right front, left front, left rear).

5. Final Inspection and Reassembly

Recheck all connections and ensure there are no leaks.
Reinstall the wheel and torque the lug nuts to the manufacturer's specification.
Test the brake pedal for firmness before driving.
