Frequently Asked Questions
Where does this brake hose install?
The catalog lists it for the front-left and front-right positions, as the flexible link between the rigid brake line and the caliper. Sold individually — order two to cover both front sides.
What is it made of?
The hose is EPDM rubber with a rubber outer sleeve, and both fittings (male End 1, female End 2) are treated steel with a corrosion-resistant coating.
Does it include mounting hardware, a bracket, or a gasket?
No. Mounting hardware, bracket, and gasket or seal are not included; consult the vehicle service information for the correct fasteners and whether they may be reused.
Will it fit my truck?
It's cataloged for many 1987-1998 International medium-duty models (M1600/M1400 Metro II, 4600, 4700, 4800, 4900, 3800, 1652 and more). Check the "Vehicles it fits" section for your exact year and model.
How do I know if my brake hose needs replacing?
Signs a brake hose may need replacing include cracking, bulging, leaks, or a soft, spongy pedal. Diagnose the cause first; if the hose is at fault, this replaces it.
