EBC sub-contracts the blending of its brake fluids to a UK based company who specialise in the OE supply of quality brake fluids and are considered a suitable quality partner. EBC offers five brake fluid options for the market separated into two families, both of which are very different in their chemistry – glycol fluids and silicone fluids.

EBC brake fluids imageMost modern cars and motorcycles use a glycol fluid in their system. Care should be taken to read your owners manual before buying or mixing brake fluids; adding the wrong fluid to your vehicle brake system can cause many problems and even degrade the seals in your brake hydraulics. The specification and toxicity info (COSHH and OSHHA) for our brake fluids can be found by clicking on the Material Data Safety Sheets below.

Our BF307+ high performance Super DOT 4 brake fluid has been specially formulated to provide outstanding performance for braking systems routinely operated at extreme temperatures making this fluid ideal for fast street use, track days and racing. Do not mix BF307+ brake fluid with other brake fluids or its high performance may be compromised.

  • Available in two bottle sizes – 500ml (16.9 US fl.oz) or 1 litre (33.8 US fl.oz).
  • Typical dry boiling point – 310°C (590°F). Typical wet boiling point – 204°C (399°F)

NOT SUITABLE FOR USE WITH MINERAL OIL SYSTEMS. If in doubt consult vehicle handbook.

This product conforms to and exceeds the current specification U.S. FMVSS No.116 DOT 4.

DOT 4 brake fluid is a high quality brake fluid recommended for use in the hydraulic brake and clutch systems of all cars, commercial vehicles and motorcycles for which a glycol based DOT 3 or DOT 4 fluid is specified. With a higher boiling point than DOT 3 fluid, this fluid is ideally suited for higher performance vehicles where the braking system routinely reaches moderate brake temperatures.

  • Available in a choice of two bottle sizes – 250ml (8.8 US fl.oz) or 1 litre (33.8 US fl.oz).
  • Typical dry boiling point – 270°C (518°F). Typical wet boiling point – 170°C (338°F).

NOT SUITABLE FOR USE WITH MINERAL OIL SYSTEMS. If in doubt consult vehicle handbook.

This product conforms to and exceeds the current international specifications U.S. FMVSS No.116 DOT 4 & DOT 3, SAE J1703 & J1704 and ISO 4925 (Classes 3 & 4).

DOT 5 silicone brake fluid is a very high specification fluid based on polydimethylsiloxanes (silicones) and offers many advantages over conventional glycol based fluids. Silicone fluid does not absorb water from the surrounding atmosphere while in service and therefore offers greatly extended service life whilst improving corrosion resistance of the main components of the braking system.

Recommended for use in the hydraulic brake and clutch systems of all cars, commercial vehicles and motorcycles for which non-petroleum based fluid is specified. Particularly recommended for classic cars or vehicles that are garaged for much of their life but must be usable at short notice.

This fluid must only ever be mixed with DOT 5 fluid which has the same silicone base. Never mix DOT 5 with regular glycol based fluids.

  • Available in a 250ml (8.8 US fl.oz) bottle only.
  • Typical dry boiling point – 300°C (572°F). Typical wet boiling point – 180°C (356°F).

This product conforms to and exceeds the current international specifications U.S. FMVSS No.116 DOT 5.

COMING SOON – DOT 4LV low viscosity brake fluid is a very high specification brake and clutch fluid, exhibiting exceptional viscosity performance even at low temperatures (max. cSt @ -40°C) which makes this product especially recommended for use in the hydraulic brake and clutch systems of modern vehicles fitted with ESP/ASR (Electronic Stability Program) systems. This product can be mixed with other glycol fluids of the same base and is recommended for use in the hydraulic brake and clutch systems of all cars, commercial vehicles and motorcycles for which a glycol based DOT 3 or DOT 4 fluid is specified.

  • Available in 500ml (16.9 US fl.oz) bottle only.
  • Typical dry boiling point – 266°C (511°F). Typical wet boiling point – 173°C (343°F).

NOT SUITABLE FOR USE WITH MINERAL OIL SYSTEMS. If in doubt consult vehicle handbook.
This product conforms to and exceeds the latest ISO 4925 Class 6 standard. It also meets current international specifications U.S. FMVSS No.116 DOT 3, DOT 4, SAE J1703, SAE J1704 and ISO 4925 (Classes 3 & 4).

COMING SOON – DOT 5.1 high performance brake fluid is recommended for use in the hydraulic brake and clutch systems of all cars, commercial vehicles and motorcycles for which a non-petroleum based fluid is specified. DOT 5.1 has a significantly higher boiling point than standard DOT 3 and DOT 4 fluids and is therefore well suited to modern high performance vehicles and/or vehicles fitted with ESP/ASR systems. Can be mixed with other glycol fluids of the same base e.g. DOT 3, DOT 4 and DOT 5.1 fluid types.

  • Available in a 500ml (16.9 US fl.oz) bottle only.
  • Typical dry boiling point – 269°C (516°F). Typical wet boiling point – 184°C (363°F).

NOT SUITABLE FOR USE WITH MINERAL OIL SYSTEMS. If in doubt consult vehicle handbook.

This product conforms to and exceeds the current international specifications U.S. FMVSS No.116 DOT 5.1, DOT 4 & DOT 3, SAE J1703 & J1704 and ISO 4925 (Classes 3 & 4 and 5.1).

Glycol fluids have a hygroscopic characteristic – this means that they attract and absorb water. Over the years the fluid in your vehicle’s braking system will degrade by the absorption of water. It is not uncommon to find glycol fluids containing up to 13 or 14% water which corrodes internal steel parts in your brake system and will promote early brake fade under heavy brake use. For this reason, glycol fluids should be used only from a sealed container. Once opened, the container will start the degradation process immediately.

For this reason EBC Brakes do not sell large containers of brake fluid which have a definite shelf life and prefer to sell only in smaller bottles so that the fluids can remain sealed until used thus minimising waste.

Glycol fluid is highly corrosive and contact with paintwork by fingers contaminated with brake fluids can cause severe paint damage. Ensuring that you do not touch paintwork and cleaning hands is essential when working with glycol.

Silicone fluids are commonly classed as DOT 5 and MUST NOT be mixed with glycol fluids. Many US-built custom big twin motorcycles have brake systems that are designed for use with silicone brake fluid. Silicone is expensive but has the advantage that it is not hygroscopic i.e. it does not degrade by absorbing water and it does not damage paintwork.

Ensure that you choose the right brake fluid for your vehicle by always referring to the owner’s manual.

This is a general purpose glycol fluid with a dry boiling point of 270°C (518°F) and a minimum wet boiling point of 170°C (338°F). Suitable for use in most modern motorcycle and automotive brake systems. MUST NOT be mixed with DOT 5 silicone fluids.

For track or race use, choose BF307+ racing brake fluid.

A highly refined DOT 4 glycol fluid that has less tendency to cause vapour lock. Remember that once you open this container it will start to degrade. After use, remember to seal your vehicle’s brake system and discard the remainder of the bottle. MUST NOT be mixed with DOT 5 silicone fluids.

Unlike glycol fluids, silicone will not damage paintwork is used as standard in some high quality US-built big twin motorcycles. Always check your vehicle owner’s manual and do not mix this fluid with glycol fluids to prevent damage to hydraulic seals and the entire brake system.

DOT 4LV low viscosity brake fluid can be mixed with other glycol brake fluids of the same base. Recommended for use in all cars, commercial vehicles and motorcycles which require a DOT 3 or DOT 4 fluid.

DOT 5.1 high performance brake fluid has a higher boiling point than DOT 3 and DOT 4 fluids which makes it suitable for modern high performance vehicles. Can be mixed with other glycol fluids of the same base.
