PEAK BRAKE FLUID DOT 4
PRODUCT DESCRIPTION
PEAK BRAKE FLUID DOT 4 is a premium, high performance, high boiling point heavy-duty brake fluid for superior performance in the conventional disc and drum brake requiring FMVSS No 166 DOT 4 (ISO 4925 Class 4, SAE J1704 and ISO 4925) fluid.
PEAK BRAKE FLUID DOT 4 is suitable for use in hydraulic clutch systems, PEAK BRAKE FLUID DOT 4 comes in two different colors blue and clear.
BENEFITS
- Extremely high boiling points deliver the optimum performance of the brake system
- Excellent low-temperature viscosity resulting in an improvement in the brake response behavior
- Corrosion Protection through a specially formulated Inhibitor Package
- Optimal Lubricity avoids the abrasion of the brake system by friction
- High Elastomer Compatibility provides an improvement in Brake fluid loss
NOTE: Do not use in hydraulic/brake systems where DOT4 and DOT 5 (Silicone Brake Fluid) are specified.
