•Brake pedal feels soft or spongy

Diagnostic Steps

1
Inspect brake pads visually for wear; look for less than 1/4 inch of pad material.
2
Check for any abnormal noises during brake operation while driving.
3
Measure brake rotor thickness with a micrometer to ensure they are within specification.
4
Test brake fluid for contamination or low levels.
5
Inspect brake lines for leaks or damage.
6
Perform a brake performance test to assess stopping power.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, micrometer, safety goggles, gloves.
Park the vehicle on a level surface and turn off the engine.
Loosen lug nuts on the wheels where brakes will be inspected but do not remove them.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and wheels to access the brake components.

3. Inspect Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it without stretching the brake line.
Check the thickness of the brake pads; if less than 1/4 inch, replace them.
Look for signs of uneven wear, cracking, or glazing.

4. Inspect Rotors

Measure the rotor thickness with a micrometer.
If the thickness is below the manufacturer's minimum specification or if the rotor is warped, replace the rotors.
Clean the rotor surface with brake cleaner before reassembly.

5. Reassemble

Reinstall the caliper over the new or inspected brake pads.
Tighten caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs, but check service manual).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (usually around 80-100 ft-lbs).
