Safety Warnings

  • ⚠Always allow the brake system to cool before working on it.
  • ⚠Ensure the vehicle is securely supported on jack stands before removing wheels.

Symptoms

  • •Spongy brake pedal feel
  • •Longer stopping distance
  • •Brake warning light illuminated
  • •Fluid leak under the vehicle
  • •Unusual noises when applying brakes

Diagnostic Steps

  1. 1Inspect brake fluid level in the reservoir.
  2. 2Check for fluid leaks around brake lines, calipers, and master cylinder.
  3. 3Test the brake pedal while the vehicle is off and then with the engine running.
  4. 4Examine brake components for wear, including pads, rotors, and calipers.
  5. 5Use an OBD-II scanner to check for any error codes related to the braking system.

Solution

Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

  1. Remove the Brake Fluid Reservoir Cap

    • Tools Required: Screwdriver (if applicable)
    • Carefully remove the cap to avoid contamination.
  2. Check Fluid Condition and Level

    • If the fluid is dark or below the minimum line, it needs to be replaced.
  3. Flush the Brake System

    • Connect a brake bleeder kit to the brake caliper.
    • Open the bleeder valve and pump the brake pedal until clean fluid flows out.
    • Close the valve and repeat for each wheel.

3. Inspect Brake Lines and Components

  1. Visual Inspection of Lines

    • Check for cracks, corrosion, or leaks in brake lines.
    • Replace any damaged lines.
  2. Inspect Brake Pads and Rotors

    • Remove wheel and caliper to access pads and rotors.
    • Measure thickness of pads and check rotor surface for warping.
    • Replace pads if worn below specification (typically 3mm) and resurface or replace rotors as needed.

4. Bleed the Brake System

  1. Bleed Each Brake Line
    • Start with the wheel farthest from the master cylinder (usually the passenger rear).
    • Open the bleeder valve, have an assistant pump the brake pedal, and hold it down.
    • Close the valve before the pedal is released.
    • Repeat until no air bubbles appear, then move to the next wheel.

5. Final Assembly

  • Reinstall wheels and lower the vehicle.
  • Check brake fluid level and top off if necessary.
  • Replace the reservoir cap securely.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
  • Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

  • •Follow the manufacturer's recommended maintenance schedule
  • •Address warning signs early before they develop into major issues
  • •Use quality parts and fluids recommended for your vehicle
  • •Keep detailed records of all repairs and maintenance

Tools & Equipment Required

  • Brake bleeder kit
  • Screwdriver
  • Wrenches or sockets for caliper removal
  • Torque wrench

Parts Required

  • Brake fluid (DOT 3 or 4 as specified)
  • Brake pads (if worn)
