Common Brake System Inspection Procedures

Brake Pad Inspection

Steps:

1. Remove the wheels to access brake components
2. Visually inspect brake pad thickness (should be at least 3-4mm)
3. Check for uneven wear patterns
4. Inspect for glazing or contamination
5. Measure pad thickness with brake gauge
6. Document findings and recommend replacement if needed

Brake Rotor Inspection

Steps:

1. Clean rotor surface for proper inspection
2. Check for scoring, grooves, or deep scratches
3. Measure rotor thickness with micrometer
4. Compare measurements to manufacturer specifications
5. Check for warping using dial indicator
6. Inspect for heat damage or cracking
7. Recommend resurfacing or replacement based on findings

Brake Fluid Inspection

Steps:

1. Check fluid level in master cylinder reservoir
2. Inspect fluid color (should be clear to amber)
3. Test fluid for moisture content using test strips
4. Check for debris or contamination
5. Verify fluid age (recommend replacement every 2-3 years)
6. Document findings and recommend flush if needed

Brake Line Inspection

Steps:

1. Visually inspect all brake lines for damage
2. Check for leaks at fittings and connections
3. Look for rust or corrosion
4. Inspect flexible hoses for cracks or bulging
5. Verify proper line routing and securing
6. Test line pressure using brake pressure gauge
7. Document any issues requiring repair

Brake Caliper Inspection

Steps:

1. Check caliper mounting and sliding
2. Inspect dust boots and seals for damage
3. Verify piston movement and return
4. Check for fluid leaks around piston
5. Test caliper sliding pins for smooth operation
6. Lubricate sliding components as needed
7. Document any repairs needed

Master Cylinder Inspection

Steps:

1. Check for external leaks
2. Inspect reservoir cap and seal
3. Test brake pedal feel and travel
4. Verify proper fluid level
5. Check mounting security
6. Test brake warning light operation
7. Document any issues found

Note:All inspections should be performed by qualified technicians using proper safety equipment and following manufacturer specifications. Regular brake system inspections are recommended every 12,000 miles or annually, whichever comes first.

Safety Warning: Brake system maintenance is crucial for vehicle safety. If you notice any unusual brake behavior, have your vehicle inspected immediately by a professional technician.
