Wilwood FIVE is a highly refined silicone brake fluid, formulated to preserve the looks and reliability of classic vehicles and show cars. Its non-hygroscopic blend blocks moisture absorption to inhibit internal system corrosion. It is paint-friendly and will not harm most custom finishes should a spill or leak occur. Wilwood FIVE provides superior lubrication for all brake system wear surfaces with long life from the master cylinder and caliper pistons, bores, and seals. It is a fully DOT 5 compliant fluid meeting or exceeding FMVSS 116 and MIL-PRF-46176B-DOT specifications and can be used in any vehicle that is OE-specified for DOT 5 use. Wilwood does not recommend using DOT 5 fluid in any racing applications.
