Some cars require a DOT 4 or Dot 5. Check your specs. Wait, probably a wasted comment. If you are competent to replace brake fluid, you probably already know that.

Most cars can get a full flush with a single 32oz bottle. I usually have extra available though. You don't want to run out, and once you start the process, you don't want to skimp and leave any dirty fluid in there.

Regarding availability, my main store was out, but my second choice, about 4 miles away allowed me to buy 3.

DOT 3 and DOT 4 are often co-specified and interchangeable on most cars. The difference in the spec has to do with slightly different wet vs. dry boiling points. Both types are good for cars driven on the street. Better to change the fluid than to worry about precise details on the specs. Whatever fluid you put in there will start absorbing moisture from the atmosphere immediately, so change frequently and don't worry about brand or exact quantitative ratings. Just my opinion, which is 100% correct.

Great deal.

There's not a production vehicle that specifies DOT 5. DOT 5 is silicone based fluid is is incompatible with ABS systems.

Quote from The_Whaler :
I'd recommend checking your brake fluid to make sure it needs to be replaced before unnecessarily changing it. Manufacturer recommended intervals are often a bit ambitious. Brake fluid can be checked a couple of ways: 1) with a multimeter in voltage where you are looking for less than 0.30V or 2) with litmus paper where you are looking for a pH of greater than 7.0.
There's too many variables for either of those tests to be remotely accurate. The pH test doesn't account for the pH of the fluid when new. Different manufacturers use a different pH formulation. If yours is very alkaline, it has absorbed too much water at a pH of 7. The voltage test has so many issues between different designs of the brake master cylinder, the particular fluid (again pH varies) and the meter itself since we are discussing a very small ghost voltage. The manufacturer's service interval is trying to remove the old fluid before it absorbs enough fluid to really fail any test. By the time the fluid fails a test strip for copper content, your brake system is already braking down.

I don't know of any current production vehicles but there have been plenty of production vehicles specifying DOT 5.

I stand corrected regarding "specifications". However, many restoration shops, hot rodders, and classic cars owners, etc., pre ABS up grade to DOT 5 for the low moisture absorption characteristics and other reasons. Some race car mechanics prefer it because of its high boiling point that combats brake fade.

Others avoid DOT 5 because it can be difficult to bleed, does not play well with any other type of fluid left in the system, may result in a spongy feel on the pedal, likes to leak, and so on.

Lets not forget DOT 5.1.

For more advice, ask Google, she knows everything.

Autozone online experience is the worst... Order two. Now I got an email showing order has been canceled.. no explanation or any reason as to why they did it.

yet took money from my credit card for the online order.

complete waste of time and energy.. now I got to dispute the charge

So you shouldn't put them on top of each other?

That's good to know - I always store my chemicals side by side.

Not the problem of storing chemical side by side, the problem is brake fluid lasts for about two years only, it is just going to expire and totally waste of money.
(May be even putting you in danger if you dont know it is already expired and continue to use it in your car)

DOT 5.1 or 4+ aren't real standards by the DOT but ways glycol based brake fluids are marketed to show they have higher boiling points than a standard DOT 4. Many European cars use these types of fluids.

That's only an issue if it has been opened and moisture is allowed to enter the container. As long as the seal is intact, you don't have to worry.

If you stand by what you said then list one. DOT 5 is silicone based brake fluid only used in racecars. All road cars for as long as there was a DOT spec have used glycol based fluid.

Can you just please shed some light on why you feel the need to make completely false statements? It's completely annoying.

*Sigh*. No way. Dot 5 is silicone based? OMG I'm a complete moron. Seriously though, it must be hard being you. Since you need to be spoon fed, basically every Harley-Davidson that rolled off the line from the mid-70s through the mid 2000s was spec'd for Dot 5.

Now class, let's review- I said:

"I don't know of any current production vehicles but there have been plenty of production vehicles specifying DOT 5."

Now stop being annoyed and go back and like my post. Then go sit in the corner and think about what you've done.
