As an IATF 16949 & E-mark certified ceramic brake pads manufacturer, Frenobrake has delivered over 8 million noise-free brake pads to European and global OEMs. Through our rigorous quality control system, we’ve identified three systemic causes of brake noise – and more importantly, how to eliminate them at the production level.
Problem #1: Material-Rotor Compatibility Failures
Why It Happens Under ECE R90 Standards
High-pitched squealing (＞5kHz) often occurs when:
- Ceramic friction material hardness doesn’t match rotor specs (per ECE R90 Annex 5 testing)
- Temperature range exceeds E-mark certification limits (e.g., urban driving vs. performance applications)
Our IATF 16949 Controlled Solution
Dynamic Friction Testing
- SAE J2522 + ECE R90 Annex 7 compliance
- Customized low-noise ceramic compound (see our ceramic compound formula)(see our ceramic compound formula)
Material Traceability
- Batch-level documentation per IATF 16949 §8.5.2
- XRF spectroscopy to verify heavy metal compliance (EU Regulation No 465/2012)
Problem #2: Non-Conforming Chamfer Geometry
E-mark Certification Gap Analysis
Many noise complaints stem from:
- Chamfer angles deviating beyond ±0.05mm tolerance (vs. ECE R90 §6.2.3)
- Mold wear exceeding IATF 16949 preventive maintenance thresholds
Our Process Controls
- Laser QC Every 50 Pads (IATF 16949 §8.6.2)
- EMARK-Approved Die Designs (30°/45°/60° options)
- PPAP Documentation for all custom geometries
Problem #3: Inadequate Bed-in Procedures
Legal Risks Under EU Market Surveillance
Improper bedding causes:
- Premature noise complaints (＞72% of warranty cases)
- Non-compliance with ECE R90 Annex 9 durability requirements
Our Compliance-Backed Solution
Laser-Etched Bed-in Instructions
- Multilingual guidelines engraved per UN Regulation No. 90
- QR code linking to video instructions
Customer Training Kits
- IATF 16949 §7.2.3 compliant training materials
- E-mark test reports included with bulk orders
