I was hoping to flush the brake fluid today, but could not find any Dot 4 anywhere.

The most I found is the Dot 3/4. I am a little hesitate to use it.

The fluid in my brake system is not synthetic and I would like to stay consistent.

Does anyone know where I can find Dot 4 brake fluids.

I hate to order something online pay $10 shipping for 2 liters of brake fluids. I'd rather pick it up in local auto supplies store if you know what I mean.

Oh, I went to autozone in Braintree and some smaller stores. They don't have Dot 4.

 

If the fluid says it is 4 complaint, you are good to go.

 

bobs speed shop quincy ma?

 

i don't know what motorcycle's use weymouth honda has a motorcycle shop too

 

Thomas, I've seen it at Pep Boys and Auto Zone.

 

I've checked. They have the Dot 3/4 ones (synthetic).

All I need is Dot 4 conventional, because that is what I have in the car now.

Good news, Vdub dealership in Allston has some Dot 4 brake fluid. I am going there after work.

 

Technically...isn't all moden brake fuild synthetic?

 

"In the USA brake fluid comes in a number of forms, standardized under by the United States Department of Transportation (DOT). DOT 2 is essentially castor oil; DOT 3, DOT 4, and DOT 5.1 are composed of various mineral oils, glycol esters, and ethers; some are synthetic oil based, and DOT 5 is silicone-based. As of 2006, most cars produced in the U.S. use DOT 3........"

If some are synthetic oil based, that means the rest is mineral oil based then.
