Problems and solutions for flexible metal hose
A brake hose assembly consists of two key components: the auto hose (flexible tubing) and its permanent crimped joint. This secure connection ensures reliable performance under pressure.
Performance Standards
Max Expansion: At 6.9 MPa and 10.3 MPa, expansion must not exceed specified limits (see Table 2).
Burst Strength: Each brake line must withstand 27.6 MPa for 2 minutes without failure, with a minimum burst pressure of 34.5 MPa.
How to Choose the Right Brake Hose
Certification Matters: Only select hoses from certified brands displaying CCC marks, production dates, and clear labeling.
Match Your Vehicle:
Identify hose markings: “HR” (standard expansion), “HL” (low expansion).
“A” denotes air brake hose systems. While “V” indicates vacuum brake compatibility.
Inspect Before Use: Never install hoses with cracks, corrosion, or bubbles.
Essential Maintenance Tips
Regular Cleaning: Prevent corrosion by keeping the auto hose surface dirt-free.
Avoid Strain: Protect hoses from external pulling or twisting forces.
Check Connections: Ensure joints remain tight and leak-free.
Timely Replacement: Replace aging, scratched, or poorly sealed brake lines immediately.
Why Proper Care Matters
A well-maintained air brake hose is critical for vehicle safety. So follow these guidelines to ensure optimal performance and longevity.
