What Does the Rear Brake Hose Do?
The rear brake hose is a vital component of the hydraulic
braking system.
Its primary functions include:
- Carrying
brake fluid under high pressure to the rear brake caliper.
- Allowing
suspension and steering movement without stressing the brake lines.
- Maintaining
consistent hydraulic pressure during braking.
- Providing
safe and reliable brake operation.
- Helping
deliver firm brake pedal feel and consistent braking performance.
A correctly functioning brake hose is essential for
maintaining safe braking under all driving conditions.
Why Do Rear Brake Hoses Wear Out?
Brake hoses operate in a harsh environment and are
continually exposed to pressure, movement and the elements.
Common causes of deterioration include:
- Rubber
ageing and hardening.
- Cracks
caused by repeated flexing.
- Exposure
to road salt, dirt and moisture.
- Internal
deterioration caused by ageing brake fluid.
- Abrasion
from contact with surrounding components.
- Damage
from impact or incorrect installation.
As brake hoses deteriorate, they can restrict brake fluid
flow or develop leaks, reducing braking performance and compromising safety.
When Should the Rear Brake Hose Be Replaced?
Replacement is recommended when:
- The
hose shows visible cracks or splits.
- Brake
fluid leaks are present.
- The
outer rubber has become swollen or perished.
- Corrosion
is present around the hose fittings.
- Replacing
brake calipers or rear brake pipes.
- Carrying
out a complete brake system overhaul.
- Performing
preventative maintenance on higher-mileage vehicles.
It is good practice to replace brake hoses in axle pairs to
maintain balanced braking performance.
