eezibleed with twin master cylinders?
daniel mason - 4/1/12 at 09:46 PM

do the same principles apply when using gunson eezibleed with twin master cylinder arrangement? eg just force the pressurised fluid to brake fluid chamber?
is there a sequence of which calipers to bleed first or should i jack the rear up and bleed the fronts first? is 20 psi a reasonable tyure pressure to use? cheers

Follow normal instructions, and know which cylinder is front do fronts etc

As above 40psi works better, a hose nipp can be very handy to control the air flow.


If you have oridinary tintop style hoses you can also use a hose nipp to control the fluid.

was just concerned about fluid flow out of the twin outlet resevoir,but i suppose if its pressurised it will pump equal ammounts to both cylinders

Is the eezibleed the system you pressure up with a "spare tyre"? If so, I thought I read that 10psi is about as high as you want to go - any higher could split the fluid resevoir.

From my experience a normally inflated tyre is perfect (ie 25-30 psi) andything less than that and it will run out of puff before you finish, (especially if your doing a full system after a fresh install or major works)

Do you have one reservoir serving both M/C?

i do mate. 2 x outlets from bottom

ReMan - 4/1/12 at 10:57 PM

sorry missed the single reservoir point, even easier then..

but why would you you jack up the back to bleed the fronts?

loggyboy - 4/1/12 at 11:10 PM

All you need to do is wack the system on, bleed the one axel at a time (assuming you have a front/rear split), and just make sure you check the fluid level between each, as if it drops to low you will need to bleed them all through completely and start again!

just work them a seperate systems bleed one master cylider and its paired axle then refill gunson and do the second master cylider and its paired axle i normaly go for 20-25 psi but depending on the size of tyre you may have to pump it up half way through

The problem with using more than about 15psi is getting the eezibleed cap to seal on the reservoir, I always found more you woulod get fluid leaking from the cap/seal. Better to try with less pressure to start with IMHO

He cant do them seperately as he only has one reservoir to secure the ezibleed to!

Don't even think about running it at over 20 psi or it will pi$$ out every where. At 40 psi it will blow it out all over you paint! 15 psi is more than adequate.

It doesn't matter that there is only one reservoir it will just pressurise both master cylinders all the time

Always had a problem with Eezi bleed getting to seal, leaking, correct pressure etc. Ended up buying a Mitvac works brilliantly.

same here - ended up buying this -> Linky

haven't used it yet as i'm full of cold

I found the seal is very variable depending on the type of master cylinder e.g. it works perfectly with old minis that use the tin reservoirs and small caps. I have a MityVac and it's pretty good, but you have you seal the bleed nipples with lots of grease or you get air sucked in through the threads which makes it impossible to tell if there is any air left in the system. It also failed to bleed the front calipers on my bike properly, despite passing a vast amount of fluid through. Eventually I bodged the easybleed onto the master cylinder and it bled the air out instantly.

took me a while to get a decent seal on my wilwood cylinders with the easibleed. ended up having to take another rubber seal out of the other caps to make it work, ended up with a resevoir full to the top and overflowing with fluid, and still didn't get the brakes bled. wasn't a proper effort on my part though, was just trying it out really, but with some care, they are very useful

I agree

I resorted to replacing the easibleed cap with the one of the actual resevoir by drilling a hole in it and fitting the pipe!

DRCorsa - 5/1/12 at 12:38 PM

Why not bleed them the old traditional way?
I have not any experience on easibleed, but i feel that while it requires only one person, it adds some complexity to the process.

daniel mason - 5/1/12 at 12:42 PM

it said on intructions that when using twin master cyliders to jack up the rear and bleed the fronts. thats why i suggested it.
