Hi,

Sorry for posting in the wrong section but as this is quite common i was hoping for a quick response on here.

I have fresh dot4 fluid in, and i want to put my rbf600 in. How should i go about doing this?

Am i ok to fully drain the system on each corner to just air. Then fill the reservoir with new fluid and pump it through. Or will this make blockages somewhere which other than normal bleeding wont clear?

Hope someone can advise.

Thanks

Chris

Ok. Whats the actually amount of fluid in a full system?

Im thinking if i bleed out and top up as i go. Then ill be able to work out how much ive bled out, based on how much ive put in.. And can then guess when the old crap is out and the new stuff is fully in and near the caliper..

What you rekon on this method?

The easiest way is to bleed furthest away from master cylinder nsr keep topping up and go to each wheel finishing with osf.

Problem is i need to know when the old stuff is out and the new stuff is in. As the performance difference between the two is quite large. Dont wanna waste rbf600 at the price of it, and dont want most of it in but dot4 left at the calipers.

I think ill just go at it till i think its done. The dot4 is only 3 days old so cant even do a dirty clean thing lol.

So whats the capacity of the braking system?

Don't drain it to air!
What method are you going to use! You need a pressure system of some kind to push the new fluid through.
To make sure you get rid of pretty well all the old fluid, you'll need a couple of litres.
I use the Gunson Ezibleed which uses air pressure from a spare tyre, but for the Subaru you need the universal reservour cap as the supplied caps don't fit.

I was not going to use a pressurised system as i have a nonmembraned one man kit.

Instead my brother is going to be manually pumping the stuff through.

I have two liters. I suspect it will store approx 1.5 liters which means i can go into my final bottle and be fairly confident all the old stuff is out.

Going to do a few (perhaps 10) pumps on each corner to get the old out whilst topping up with the new. This should evenly pull the new fluid into each corner. Dont want to end up with 3lines with rbf and one with dot4.

There doesnt seemed to be a good way to do this other than buying ATE superblue.

Im sure my method will work. if it doesnt ill change the method or i just wont know .
