RAL Brake Fluid DOT 4
RALBrake Fluid DOT 4s a heavy-duty synthetic brake fluid, contains antioxidant, metal deactivator and corrosion inhibitor to ensure long service life of brake fluid and brake components. Due to high boiling point, it does not give vapor lock problems in high temperature working conditions
Application
- For automotive applications where a DOT 4 fluid is specified. It should not be used where DOT 5 or mineral oil-based fluids are specified..
Benefits
- High boiling point
- Minimum rubber component swell
- Excellent corrosion protection
- Specification
- Meets and exceeds:
- FMVSS No. 116 DOT 4; SAE J1703
