Master Cylinder Reservoir Filling

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Refer to Brake Fluid Irritant Caution .

NOTE: When adding fluid to the brake master cylinder reservoir, use only GM approved or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container. The use of any type of fluid other than the recommended type of brake fluid may cause contamination which could result in damage to the internal rubber seals and/or rubber linings of hydraulic brake system components.

NOTE: Refer to Brake Fluid Effects on Paint and Electrical Components Notice .

Visually inspect the brake fluid level through the brake master cylinder auxiliary reservoir.
If the brake fluid level is at or below the half-full point during routine fluid checks, the brake system should be inspected for wear and possible brake fluid leaks.
If the brake fluid level is at or below the half-full point during routine fluid checks, and an inspection of the brake system did not reveal wear or brake fluid leaks, the brake fluid may be topped-off up to the maximum-fill level.
If brake system service was just completed, the brake fluid may be topped-off up to the maximum-fill level.
If the brake fluid level is above the half-full point, adding brake fluid is not recommended under normal conditions.
If brake fluid is to be added to the master cylinder auxiliary reservoir, clean the outside of the reservoir on and around the reservoir cap prior to removing the cap and diaphragm.
