pressure loss

[FE3-323]

hrmm i suppose i'll just see what happens.

[13thghost]

i had the same problem when i chage 2 stander

[13thghost]

my mecanic faund the problem ??

[13thghost]

just take a bolt longer then the stick thets in the sleve and cut the bolt a littel longer and thet will make up for the lost of pressure

[13thghost]

i dont know it sound stupid but it work's

[FE3-323]

are you implying a longer slave cylinder pushrod???

If so i already have one.

Ok, sounds like a good idea, but A: Don't you have to roundover the end and put the nipple on so it stays in the arm? and B: Don't you run the risk of pushing the throwout bearing off of the shaft it rides on? and C: Am I able to use the Synthetic DOT 4 after using regular brake fluid, (ie..Does it cause any leaking?).

[FE3-323]

if you extend the pushrod properly & grind it accordingly to fit in the slave cylinder piston you won't have issues, I know jack about dot4 synthetic.

[91scortgt]

What did you use to make yours?, and how much longer than stock?

I was hoping rusty would clue us in on the DOT 4.
Using synthetic does seem like a better idea, but like you said I don't want to have issues after converting to it.

i cut 2 pushrods welded them together & ground it down to my liking.

Does synthetic DOT 4 pass by the seals if you've previously run regular non-synthetic & change or what?? I don't want to replace my calipers all over again.

It doesn't in my car.

I just use what we buy by the gallon at work....it's free for me.

Off the top of my head, I'm pretty sure it's Castrol Synthenic that exceeds Dot 3 and 4 ratings.

Cool, sounds like it's time for another well deserved upgrade.

As long as you are not converting to dot 5, using dot 4 sythetic you don't have to change any parts out. I would just recommend bleed the old fluid out.

[91scortgt]

Are there going to be any leaks going from regular fluid to synthetic?

As long as you are not converting to dot 5, using dot 4 sythetic you don't have to change any parts out. I would just recommend bleed the old fluid out.

Right.

Dot 3 and DOT 4 are compatible. DOT 5 is silicone based.


You shouldn't have any leaks when converting to synthetic.
