Note: When adding brake fluid to the master cylinder reservoir, use only Delco Supreme 11 fluid or equivalent (DOT-3) from a clean sealed container.
1. Assess the level of brake fluid in the master cylinder reservoir.
2. If the brake fluid level is below the midpoint of the regular level checks, have the brake system checked, see above.
3. If the system check showed no noticeable damage or necessary repairs were made, add brake fluid to the maximum level.
4. If the brake fluid level is above the midpoint of the regular level checks, topping up fluid is not recommended.
