  • Total Items: 29
  • Compliance: FMVSS 105 (Hydraulic Brake Systems), FMVSS 121 (Air Brake Systems), ASE A5 Brakes Certification Standards, NATEF Brake Service Task Standards, SAE J866 Brake Lining Standards

Brake Pad / Shoe Thickness Measurement

Measure and document brake pad/shoe thickness on all four corners. Minimum thickness varies by vehicle; typically 2mm (1/16") is the absolute minimum - recommend replacement at 3-4mm for safety.

  • Left Front - Inner pad thickness (mm)?
  • Left Front - Outer pad thickness (mm)?
  • Right Front - Inner pad thickness (mm)?
  • Right Front - Outer pad thickness (mm)?
  • Left Rear - Pad/shoe thickness (mm)?
  • Right Rear - Pad/shoe thickness (mm)?

Rotor / Drum Measurement & Condition

Measure rotor/drum thickness against manufacturer's minimum discard specification. Never machine or reinstall rotors below minimum discard thickness.

  • Left Front rotor thickness (mm) - at or above minimum discard spec?
  • Right Front rotor thickness at or above minimum discard spec?
  • Left Rear rotor/drum at or above minimum spec?
  • Right Rear rotor/drum at or above minimum spec?
  • Rotor lateral runout checked (should be under 0.05mm / 0.002")?
  • Rotors free of deep scoring grooves exceeding 1.5mm?

Hydraulic System & Caliper Inspection

Inspect the brake hydraulic system including master cylinder, calipers, wheel cylinders, and brake lines for leaks and proper function.

  • Master cylinder fluid level between MIN/MAX and no external leaks?
  • Brake fluid clear (not dark/black) and moisture content under 3.5%?
  • Caliper slide pins lubricated and moving freely (no seized calipers)?
  • Caliper dust boots intact - no cracks, tears, or fluid contamination?
  • Flexible brake hoses soft, no external cracking, bulging, or internal collapse?
  • Steel brake lines free of corrosion, damage, and secure mounting?

ABS, ESC & Electronic Brake Systems

Verify ABS, ESC, and electronic parking brake systems are fully functional.

  • ABS warning light extinguishes after startup (no active fault codes)?
  • Electronic stability control (ESC) system functional - no warning light?
  • ABS wheel speed sensors inspected - no damage, correct gap?
  • Brake pedal firm at mid-stroke with no spongy feel or fade?
  • Parking brake holds on 20% grade and releases fully?

Service Recommendations & Documentation

Document brake findings and communicate recommendations to customer with written documentation.

  • Brake service urgency rated (OK / Monitor / Service Soon / Safety Stop)?
  • Front brake service recommendation documented (pads/rotors/calipers)?
  • Rear brake service recommendation documented?
  • Brake fluid flush recommended (over 2 years old or >3.5% moisture)?
  • Customer notified of all brake findings verbally and in writing on repair order?
  • Photos taken of worn pads, rotors, or brake defects to show customer?
