Step-by-Step: What Mechanics Check During a Brake Inspection

Brake Pad Thickness Check

Mechanics first inspect brake pad thickness. Thin pads cause squealing, longer stopping distances, and rotor damage. Pads should be replaced at 3mm or less to maintain safety.

Brake Rotor and Drum Inspection

Your brake rotors or drums are checked for cracks, grooves, and warping. Damaged rotors can cause vibrations and reduced stopping power. If they’re too thin or warped, they may need resurfacing or replacement.

Brake Caliper Function Test

The brake calipers are tested for leaks, sticking pistons, and uneven pad wear. Calipers must work correctly to ensure balanced braking.

Brake Fluid Level and Quality Check

The brake fluid is inspected for level and contamination. Dirty fluid causes a spongy pedal and poor performance. Most experts recommend a brake fluid flush every 2–3 years.

Brake Hose and Line Examination

Brake hoses and lines are examined for leaks, cracks, and corrosion. Any damage can lead to dangerous brake failure.

Emergency Brake (Parking Brake) Test

The parking brake is tested to ensure it can hold the vehicle securely, which is especially important on slopes and for passing state inspections.
