Have 82 with no history.Master cylinder and calipers are "New".Master cylinder casting has "Use DOT 5 Only".How do i test to verify type of fluid.DOT 5 is silicon and i have never seen,felt or smelled DOT 5. :nopity :nopity

 

Hmmmmm......why would you be interested in getting new calipers if you have new ones....perhaps for your 73-454?

That is a first......now I've read everything

 

Must be a motorcycle master cylinder.

 

Does the label say "DOT 5" or does it say "DOT 5.1"?

DOT 3, DOT 4, and DOT 5.1 are glycol based and are compatible. DOT 5 is silicone based and is not compatible with glycol based fluids. DOT 5 and DOT 5.1 are therefore not compatible.

The only way to convert a system to DOT 5 is to remove and rebuild all the hydraulic parts using DOT 5 as assembly lube. DOT 5 fluid contains a blue dye to make it easier to avoid accidentally adding it to the wrong reservoir. It's surprising how often this happens in the real world.

DOT 3 (4/5.1) brake fluid is hydroscopic (it will absorb water). You might purchase a bottle of DOT 5 brake fluid and a bottle of DOT 3 brake fluid. Take a sample of about 3-4 tablespoons from each. Into these samples put a drop of water. Do you get an "oil and water" type effect where the water is not absorbed into the fluid?

Now try the same experiment on a sample of the brake fluid drawn from your master cylinder. Do you get the same effect?

The reaction of water to the known DOT3 and DOT 5 samples, and any color (dye) differences in comparison to the sample drawn from your master cylinder, should identify which type brake fluid you have.

I won the 82 vette in a bar room contest.1st contest was the no rules brawl which i won.Then was the knife fight that i won.Had the loser survived the knife fight we were to compete in a gunfight.
Now to the free vette.It had all new brakes parts put on in 2001 but had only been driven 3214 miles.As you know "New don't mean good".
I want VBandP O'Ring Calipers and i make good money working the Honky Tonks and entering any kind of contest or event that involves money. :reddevil :reddevil

 

uh huh...... :leaving:

 

Hi George :hurray: :seeya :seeya

 

The best think for you to do is pay for a classic car inspector. He'll tell you what needs to be done with your vette. The good and bad problems. Inside and outside. :smash: :banghead:
