Book calls for dot 4 brake fluid,but all I can find is dot 3 an 4 Valoline makes it.Is this ok to use or do I have make a trip to the stealer

 

There is a chemical difference between the two types. You could have some component seal failures (unlikley) if you use dot 3 in a dot 4 system. Also dot 4 has a higher heat rating then dot 3.

You should be able to find dot 4, I'd keep looking.

 

dot 4 try auto zone or an o'rieliys they should have it

 

You should be able to find DOT4 at any auto parts store

 

Absolutely do not use dot 3. you need dot 4.

 

Didn't they use DOT 5 for a couple of years?

I should really change out my brake fluid.........27000 miles on it so far, I'm sure it's pretty nasty.

What years used which fluid?

I think they changed from DOT 5 to DOT 4 in 2005.

I am still using DOT 5
Do not use DOT 3 ( seal failure )

Peter

 

My '04 Ultra uses dot 5 (silicone). Do not mix as others have said.

 

Vavloline an castrol make a brake fluid that says on the bottle for dot 3 an dot 4 or exceeds dot 3 an dot 4 , I hit 4 auto parts stores today an no dot 4 brake fluid. Is it just bad timing hitting the stores .
