What is a brake hose replacement?
When getting a brake hose replacement service, the mechanic will assess the hose to confirm that a replacement is needed. The mechanic will also check all other hoses and lines to see if others are due for a replacement and to check for bad brake lines.
The brakes need the brake hose to function—it is a flexible pipe linking your rigid brake line to the brake caliper or wheel cylinder. Because the brake hose is flexible, it adjusts to your wheel movements easily.
If the brake hose is leaking, insufficient brake fluid will reach the brake caliper. Without sufficient hydraulic pressure to force the brake caliper closed, clamping the brake pads against the rotors or the brake shoes against the drum, the brakes would not be able to function at full capacity. A snapped hose would cause the brakes to lose their function completely.
How do I know if my brake hose is faulty?
If you see any physical damage or seepage, it's time to replace your brake hose.
Other signs to look out for that may indicate a damaged brake hose include:
Brake warning light—if there are issues with any part of your brake system, your vehicle’s brake warning light should activate
Physical damage—cuts, cracks, abrasions, bulging, or rust at the hose fitting ends
Internal hose failure—can cause fluid blockages and is diagnosed using test gauges
End of lifetime—if you haven’t changed your hose in 10 years, it’s best to replace the hose
How often should a brake hose be replaced?
Like most other brake system components, brake hoses are designed to be durable and last. However, depending on your brake hose's material, they may experience corrosion from exposure to moisture and salt, or they can be flattened and interfere with fluid flow back and forth.
That said, steel brake lines and rubber or steel hoses don’t have a recommended replacement schedule—they typically won’t need replacing unless something goes wrong and they become damaged. Rubber hoses generally last about six years, while stainless steel hoses are more durable and can last between seven and fifteen years. Still, you should have them inspected during routine car maintenance
. Can I replace my brake hose myself?
If you’re handy in the automotive department and looking for a DIY job, replacing your brake hoses is possible from home—as long as you have the right tools. But if you’re not confident in your automotive repair knowledge and are hesitant about tackling the job, leave it to a professional mechanic to change your brake hoses.
