Your vehicle’s brake lines might be corroded yet you won’t know it unless 
you are aware of the warning signs. Here is a quick look at the top clues 
that indicate your vehicle’s brake lines have corroded or are in the process 
of corroding.
A VISUAL INSPECTION THAT REVEALS CORROSION OR RUST
The most obvious sign that your vehicle’s brake lines are corroded might 
be found during a visual inspection. If you notice corrosion or rust on your 
brake line, it may be time to replace the line.
VISIBLE MOISTURE
If the brake lines show moisture or staining resulting from moisture, it is a 
sign that brake fluid is leaking. Leaking brake fluid is a serious problem as 
these lines are generally comprised of steel and should be able to endure 
considerable pressure. However, there is the potential for damage to occur 
and leaks to form. If even a small amount of brake fluid leaks when the 
brakes are pressed, repair or replacement will be necessary.
SQUEAKING OR SQUEALING NOISES WHILE THE VEHICLE IS IN MOTION
Even a slightly high-pitched sound that emanates from the automobile 
when the brakes are pressed is a sign there might be brake line corrosion. 
This sound is also a clue that the brake pads are excessively worn and 
require replacement to prevent rotor damage.
THE BRAKE WARNING LIGHT IS ILLUMINATED
The illumination of the brake warning light indicates the brake line fluid is leaking, 
there is a problem with the brake pads, and/or brake line corrosion is present. If 
this warning light is lit, it is a sign the brake fluid has leaked lower than an 
acceptable level and your attention is necessary.
BRAKING CAUSES VIBRATION OR WOBBLING
If the steering wheel shakes or vibrates or if the vehicle wobbles when the brakes 
are applied, it is a sign the rotor is uneven or the brake line has been 
compromised.
THE BRAKE PEDAL HAS A SOFT OR SPONGE-LIKE FEEL
If the brake pedal’s resistance has changed, meaning it feels more like a sponge or 
simply feels softer when applying pressure, it is an indication your vehicle needs 
prompt service. The brake line might be corroded or there might be moisture 
within the braking system. It is even possible air has made its way into the system 
or there is an issue with the master cylinder.
THE BRAKES GRIND
If you feel grinding in the brake pedal upon the application of pressure, it is a clue 
the brake line might be corroding. However, there is also a chance there is a rock 
or gravel caught within the caliper unit. Furthermore, there is also a chance the 
brake pads have suffered excessive wear and tear.
