- Commodity name： SAE J1401 Hydraulic Brake Hose 4.8mm ID EPDM SUV MPV JUNZE
- Description
-
Where a 3.2mm line limits fluid delivery — heavier curb weights, longer brake circuits, multi-piston calipers — this 4.8mm ID hydraulic brake hose steps in. The larger cross-section moves noticeably more brake fluid per pedal stroke, cutting response lag on SUV and MPV platforms without changing the vehicle's system architecture.
Construction matches the certified JUNZE process: EPDM inner tube for DOT3 and DOT4 compatibility, dual PVC yarn braid reinforcement, and an ozone-resistant EPDM outer cover. Expansion stays controlled at 1.81 ml/m under 6.9MPa for the larger bore, and the 12.5mm OD profile fits standard bracket clips and grommets on most SUV and MPV platforms.
