SPEC OIL BRAKE
FLUID DOT 4
DESCRIPTION
Spec Brake Fluid Dot 4 is heavy duty synthetic brake
fluid blended mainly from glycol ethers and poly-glycols and contains corrosion
and oxidation inhibitors to enhance its natural corrosion and chemical
stability. It exceeds the two internationally recognised American Standards,
viz., SAE J1703 and DOT 4 (Department of Transportation, USA). It also exceeds
the requirements of the South African Government’s Compulsory Standard
Specification (Gazette No. 4562) and passes all important tests specified for
brake fluids, e.g. fluidity at low temperatures, evaporation, water tolerance,
compatibility, resistance to oxidation and effect on rubber.
APPLICATION
Spec Brake Fluid Dot 4 is recommended for use
in both disc and drum brake systems requiring both DOT 3 and DOT 4 fluids. It
is also used in clutch hydraulic systems.
PERFORMANCE LEVEL
SAE J 1703, DOT 4, S.A. Government mandatory
requirements.
BENEFITS
- Firm braking pressure under all
service conditions
- Excellent chemical stability and
freedom from gummy deposits
- High boiling point to prevent
vapour forming in brake systems
- Protects metals and rubbers used
in hydraulic brake and clutch systems
- Compatible with other brake
fluids meeting Compulsory Government Standards
