About to try Motive bleeder WET for first time. Question, once filled and attached in place and pressurized, what happens to all that air in the hose from Motive to brake reservoir ? Is there a way to pre load line?

Sorry. Don't know. only ever bother to use the dry method myself.

Don't worry abt the air. It'll just keep the resevoir filled . The air will not get into the system.

Don't go above 20 lbs of pressure. If you crack the resevoir, I'll be bad.

I own one and have used it many many times. The air in the tube has never made its way into the brake lines. There will always a slight amount of air in the hose. The reservoir isn't full to the brim at the beginning and that left over volume contains air. When pressurizing the system that air is replaced by fluid and the air rises to the highest point in the clear tube attached to the bleeder. I was nervous the first time as well. Make sure you pinch off the overflow line with a clamp or vice-grips. If not it wont pressurize and you'll dump fluid all over the floor by your right front wheel. I use 20-25psi on my cars.

I usually make sure that the res is pretty well full to start; this will prevent the level in the res from being driven too low before the air in the pressure line is purged out.

You can also 'prime' the line by holding the Motiv high and letting fluid fill the hose through gravity.

And don't forget to pinch off the vent line, or you will have Brake fluid everywhere. Personally I prefer to bleed dry, that way there is no clean up, but each to their own.

I usually take a lot of the fluid out of the reservoir with a turkey baster and fill with fresh fluid of course not taking it all out. That way you first brake will be getting fresh fluid sooner.

All points very true. Just want to add when done slowly undo the top of the pressure bleeder or you can have a mess. It's a little tricky as you kinda have to tighten it a little if the fluid and air rushes too quickly. Already cover the fender and surround the reservoir with a old towel so fluid doesn't rip off the paint on the inside of the frunk also.

I do it dry, easier to see when fluid is running low.

On these reservoirs, get the 993 / later style cap that is internally vented and plug the external vent line / remove it. That's what I did.

greg1990964

Good idea on the cap. What do you mean do to dry?

crg53

Dry = no fluid in the Motiv. Fill the reservoir then pressurize with Motiv. Keep an eye on fluid level, and refill as necessary.

Spyerx

yep, no fluid in the motive just keep the reservoir full, you'll only fill it 2-3 times on a full flush. i use motive at 10lbs and its fine

Removing the old hose isn't hard but it is a bit of a pain you have to remove the driver side fender liner. Getting that body plug in (the only real way is from the outside) is a test of patience. Removing the old one with the hole in it isn't too hard.

Look in my build thread First few pages you'll see some pics.

Thanks for the info. I added a speed bleeder to the clutch slave and Murphy showed up, have all the small metric wrenches and the bleeder is metric thread and takes an SAE wrench that I don't own irritating!

Spyerx

Lol. I have very few standard wrenches myself, 99% metric.
