Maintenance and Specifications
The desiccant cartridge should be replaced or rebuilt when it has been
determined that the desiccant is contaminated and does not have
adequate water absorption capacity. The desiccant change interval may
vary; it is generally recommended that the desiccant be replaced every
12 months (yearly). If experience has shown that extended or shortened
life has resulted for a particular installation, then the yearly interval can
be increased or decreased accordingly.

Hydraulic brakes - inspection and adjustment

A regular schedule for periodic cleaning, lubrication, adjustment and
inspection should be established based on the type of vehicle operation.
It is difficult to predetermine an exact maintenance interval (time or
mileage), since vehicles will be used in a wide variety of applications and
conditions. If you are uncertain of the proper schedule and procedures
for your vehicle, contact your dealer.
Inspect the brake lining every maintenance interval. Establish inspection
intervals that provide for lining replacement before damage to the disc
occurs. Excessive lining wear may expose the backing plate to the disc
causing scoring of the disc faces.
This inspection should be performed by a qualified technician and must
be in accordance with instructions provided by the service manual.
Note: Hydraulic brake system are power assisted. Braking capabilities
will be greatly reduced without engine assist.

Hydraulic brakes - fluid level

Fluid level should be at the bottom edge of the ring on each reservoir fill
port. Do not fill the master cylinder to the top of the reservoir.
Note: If brake fluid requires attention to maintain a proper master
cylinder level, this is an indication of either severe operation (pad wear)
or fluid system leakage. A more frequent and thorough brake inspection
will be required.

Hydraulic brakes - fluid precautions

The HydroMax brake system consists of two completely separate
hydraulic systems operating with two different and incompatible fluids;
power steering fluid and hydraulic brake fluid. Failure to observe
precautions preventing the contamination of either system with fluid
from the other will result in swelling and deterioration of rubber parts
leading to reduced brake performance and eventual brake failure.
