Abstract
Corrosion inhibiting hydraulic fluid additives, kits, and methods are disclosed. The hydraulic fluid additive may be adapted for use with brake fluid in vehicular brake systems. The kits may include an additive, a hydraulic fluid tester, and/or correlated information on test results and hydraulic fluid service actions.
Claims16
A corrosion inhibiting brake fluid additive configured to be added to a brake system, comprising:
- a water-soluble carrier fluid;
- and
- a corrosion inhibitor comprising an organic compound comprising an azole that, in response to addition of the corrosion inhibiting brake fluid additive to the brake system, inhibits corrosion of the brake system;
- and
- wherein the corrosion inhibiting brake fluid additive is not suitable for use, alone, as brake fluid;
- wherein the corrosion inhibiting brake fluid additive is packaged in one of:
- a volume of about 1 fluid ounce, with about 0.45% benzotriazole by weight;
- and
- a volume of about 3 fluid ounces, with about 0.15% benzotriazole by weight.

A corrosion inhibiting brake fluid additive configured to be added to a brake system, the corrosion inhibiting brake fluid additive comprising:
- a water-soluble carrier fluid;
- and
- a corrosion inhibitor comprising an organic compound comprising an azole that, in response to addition of the corrosion inhibiting brake fluid additive to the brake system, inhibits corrosion of the brake system;
- wherein the corrosion inhibiting brake fluid additive is not suitable for use, alone, as brake fluid;
- wherein the corrosion inhibiting brake fluid additive is packaged in a volume of 25% or less of a total volume of the brake system, wherein the total volume of the brake system is 3 liters or less.
2 more elements
A corrosion inhibiting brake fluid additive comprising:
- a water-soluble carrier fluid suitable for addition to a hydraulic fluid comprising used brake fluid of a brake system, the used brake fluid comprising a DOT 3, DOT 4, or DOT 5.1 brake fluid comprising a significant concentration of a corrosion product;
- and
- a corrosion inhibitor comprising an organic compound comprising an azole that, in response to addition of the corrosion inhibiting brake fluid additive to the used brake fluid, within the brake system, inhibits corrosion of the brake system;
- wherein the corrosion inhibiting brake fluid additive is not suitable for use, alone, as brake fluid.
