Product Information

Dry boiling point: >260°C (>500°F)

Wet boiling point: 155°C (311°F)


Synthetic brake fluid based on glycol ethers, alkyl poly glycols and glycol ether esters. It contains inhibitors to prevent the corrosion of metallic brake components and to reduce oxidation at increased temperatures. The brake fluid has a high wet and dry boiling point, thus ensuring safe braking even after the absorption of some moisture over an extended period of use. Special moisture scavengers help to prevent against the formation of steam bubbles.


  • miscible and compatible with high-quality syntheticbrake fluids
  • outstanding protection against the formation of steam bubbles
  • excellent elastomer compatibility
  • assures a high degree of lubricating action on all moving components in the hydraulic brake circuit
  • extremely high wet and dry boiling points
  • excellent viscosity/temperature properties
  • excellent low temperature behavior
  • highest thermal stability

Specifications and approvals:

  • FMVSS 116 DOT 3
  • FMVSS 116 DOT 4
  • ISO 4925 Class 3
  • ISO 4925 Class 4
  • SAE J 1703
  • SAE J 1704


Liqui Moly DOT 4 brake fluid can be used with all conventional brake fluid bleeding devices. Liqui Moly DOT 4 brake fluid is miscible and compatible with all highquality synthetic brake fluids. The optimal period of use for this brake fluid is, however, only ensured when it is used alone. It is recommended that the brake fluid be changed in accordance with the specifications from the automobile manufacturer.

Brake Fluid

Brake fluid is essentially hydraulic fluid which meets the standards set by the Society of Automotive Engineers (SAE) and the Department of Transportation (DOT). There are three main categories of brake fluid: DOT 3, DOT 4, and DOT 5. DOT 3 and 4 are polyglycol based while DOT 5 is synthetic brake fluid. Glycol based fluids are hygroscopic which is a benefit as the fluid absorbs any water which prevents water droplets from forming in the fluid. By absorbing the water, this in turn prevents water from collecting which could either boil, freeze or corrode components. Changing the brake fluid in your vehicle routinely will reduce the chances of boiling brake fluid which could lead to brake fade or loss of brake operation altogether.

Brake Fluid Failure Symptoms
  • High moisture content causing low boiling point
  • Dirty or tarnished color
  • Boiling over of the brake system under extreme braking conditions

Overall Fantastic

Over all fantastic. From the ordering process, to how fast the shipping is and also the customer service. This is why I only shop on GenRacer for my coupe! Keep up the stellar work

Awesome Service

I recently purchased the ARK test pipes for my 2010 Hyundai Genesis Coupe 3.8 and must say was the best thing I’ve done aside from from getting my aftermarket exhaust. Sounds louder and drives faster! No hassle, got the pipes within three days. Thank you GenRacer,

Simply the Best Service

Most places just sell parts and when you call them it feels like you are bothering them. My last transaction with GENRACER left nothing to be desired, meaning it could have not been better. I purchased front and rear WHITELINE sway bars, front & rear DBA rotors, and EBC YELLOWSTUFF brake pads. I called just after I ordered the parts because I received an "out of stock" email notification. When I called back to chat with someone *** answered the phone. He couldn't have been more knowledgeable about exactly what I was looking for when it came to the right brake pad for my needs (street/track). Come to find out the pads I picked (DBA's) were not the best pads for my application so im very glad I talked to ***!! I just recently had everything installed, bedded the pads and I am so happy I used GenRacer for my 16 R-Spec Coupe!! Thanks again ***!!!

So Awesome

Order came fast and looks amazing on my car. I did have one problem where one tail light would blink sequentially and the other didn’t. I sent an email late in the day inquiring about it. I wasn’t expecting a response until at least the following day as it was so late. Within an hour they had gotten back to me informing me of a switch on the inside of the housing where you can choose sequential or regular. Sweet! Top notch customer service.
