Tridon BF-5.1

TRIDON BF-5.1 is a brake fluid for hydraulic brake and clutch system with boiling point of at least 260℃ and an extremely high wet boiling point of at least 180℃. Because of the low viscosity at low temperatures, particularly suitable for additional systems.

According to extensive test in racing, TRIDON BF-5.1can be used in on-road and off-road motorcycles, as well as passenger cars and commercial vehicle where fluid complying to the FMVSS DOT 5.1 specification is required.


  • Mixable with DOT 3, DOT 4 and DOT 5.1 non silicon base products.
  • Do not mix with silicon (DOT 5 silicon base).
  • Stores brake fluid in its original container, tightly closed to avoid absorption of moisture.

Tridon BF-4

Tridon BF-4 is a high performance brake fluid for clutch and brake systems in passenger cars and trucks. It fulfills the new FMVSS 116 DOT 4 / DOT 3 specifications as well as SAE J 1703 / Jan. 80 (previously SAE 70 R1 and SAE 70 R3) specifications.

Tridon BF-4 was developed for heavy duty applications and may be used in all passenger cars, commercial vehicles and motor cycles manufactured in the USA, Europe or Japan where an FMVSS DOT 3 or DOT 4 fluid is specified. It offers absolute reliability at all temperature between -40oC and 270oC and guards against clutch and brake problems. It is safely miscible with all brand name fluids of the same specification but can NOT be used in certain Citroen or other vehicles requiring a special mineral oil based fluid.

Tridon BF-4 is formulated specially to provide low moisture absorption thereby maintaining the fluid’s high boiling point and is specially inhibited to ensure long term protection against rust and corrosion together with additives to provide the correct degree of seal swelling Application

Modern vehicles frequently travel at high speed and under hot weather conditions with frequent application of the brakes. Such conditions can generate very high temperatures in the brake disk or drum area. At the same time, modern body designs restrict the flow of cooling air and heat is conducted to the braking system cylinders.

All brake fluids absorb water from the atmosphere and this dilution reduces the effectiveness of the fluids which leads to “vapour lock” with spongy and excessive pedal travel during services.

Brake and clutch systems should be drained, flushed and refilled with fresh fluid at intervals recommended by the vehicle manufacturer.

Tridon BF-4 can damage vehicle paintwork and any spillage should be removed immediately by flushing with plenty of water. Do not wipe off.

Tridon BF-4, like all other brake fluids, must be stored well sealed in a dry place to minimize the possibility of contamination by dust, water or mineral oil products.

Tridon BF-3

Tridon BF-3 Brake Fluid is suitable for use in brake and clutch systems of all passenger cars, trucks, buses and motorcycles except those requiring mineral oil (e.g. Citroen). It mixes safely with all brake fluids recommended by vehicle manufacturers except those requiring mineral oil. Brake fluid additions should follow manufacturer's recommendations, but if these are not available then follow the directions below. Contamination of brake fluid with petroleum, water or other liquids may result in brake failure or costly repairs. Store brake fluid only in its original container and keep container clean and tightly closed. When this container is empty, destroy it. Do not re-use container for other fluids To Add Fluid Clean away dirt from around the filter cap of fluid reservoir and remove cap. Fill to full level and replace cap.

To Bleed the System:

Place drain tube over bleed nipple. Submerge the drain end of tube in a small amount of new brake fluid in a clean container, then open bleed nipple 3/4 of a turn. Continue to depress the brake pedal and allow it to return slowly until fluid containing no air bubbles emerges from drain tube. Keep reservoir filled while bleeding. Check after each 5 strokes of the brake pedal. Tighten bleed nipple, remove drain hose and replace plug. Repeat this procedure for each wheel then fill reservoir to full level mark and replace cap.
