Brake System External Leak Inspection
Warning: Refer to
Brake Fluid Irritant Warning .
Caution: Refer to
Brake Fluid Effects on Paint and Electrical
Components Caution .
1. |
In order to inspect for
external brake fluid leaks, first check the fluid level in the
master cylinder. |
|
While a slight brake fluid level drop can be considered a
normal condition due to brake lining wear, a very low level may
indicate a brake fluid leak in the hydraulic system. |
2. |
Start the engine and allow it
to idle. |
3. |
Apply constant, moderate foot
pressure to the brake pedal. |
|
If the brake pedal gradually falls away while under foot
pressure, there may be a brake fluid leak. |
4. |
Turn OFF the ignition.
|
5. |
Visually inspect the following
brake system components for brake fluid leaks, excessive corrosion,
and damage. Give particular attention to all brake pipe and
flexible hose connections to ensure that there are not any slight
brake fluid leaks - even though the brake pedal may feel firm and
hold steady: |
|
• |
Master cylinder brake pipe
fittings |
|
• |
All brake pipe
connections |
|
• |
Brake hoses and
connections |
|
• |
Brake calipers and/or wheel
cylinders, if equipped |
6. |
While slight dampness around
the master cylinder reservoir can be considered acceptable, brake
fluid leaking from any of the brake system components requires
immediate attention. If any of these components exhibit signs of
brake fluid leakage, repair or replace those components. After the
repair or replacement, reinspect the hydraulic brake system to
assure proper function. |
