Suck or pump?
Afternoon,
My easy bleed brake bleeding tool is doing in my nut, it's either leaking round the cap, exploding completely off the reservoir or leaking past
the reservoir seals. I can only go to 20psi which tbh is rather lame with systems like my landy which are full of bends and twists, any higher and
fluid is pouring out all over the place (usually on my paint work)
I can only put it down to useless quality of parts as the system design works it’s just what it’s made of doesn’t.
I was thinking I would be better getting a suction bleeder instead, anyone recommend me one that doesn’t cost the earth??
I have a low flow airline.
Thanks.

I use a painters syringe, they use them to mix paint colours. Bit of suitable hose, and draw it through from master to wheel cylinder. Do about a
dozen cars a year with it, never had a problem, have to be a bit patient with it, but it works. Cheap too

I think the working pressure for the EZ bleed is 20psi so any greater and it will start to leak.

You shouldn't need 20psi even a couple of psi is enough., I normally pump my Sealey VS820 up to 10 to 12 psi. If you go too higher you are more
likely to get a trapped pocket of compressed air in a calliper.
Normally I can bleed an ABS system circuit after an ABS unit to wheel brake pipe renewal in 15 seconds.
The key is not to let air into the master cylinder by not letting it drain down, use the Polly bag trick and block off open ports and clamp flex
hoses to stop fluid loss while you are making up pipes. If the master cylinder drains then the pedal must be pumped a couple times during
bleeding.

Mr Whippy.... if it's a TLS 109 (1967, SII) like mine, you'll need to remove the front backplates, rotate 180 degrees to get the bleed
nipple at the top(!), bleed and then replace. Mine has the single cylinder, single circuit brake setup which can take a long time to get working
properly - and then a short time before the wheel cylinders start to weep.
I suspect however, like everybody on here, that it's a new Evoque with ABS and a whole lot of other grief. I don't know how to bleed
those.... others may.

I didn't think the Gunsons Eeezibleed should be used above 15 psi ?
Use an electrical suction pump meself and its been really useful

There's no way you should need 20+psi to bleed a brake system. In fact with the height difference between res' and bleed points on a
LandRover it should almost gravity bleed despite the routing.

gunsons eazi bleed connects to tyre,20-25 PSI is plenty.
I've had the cap come off when doing the land rover so know all about the mess!! can't remember if I sorted it.
I made a one way cable, piece of brake pipe flared at one end that is pushed into hose that goes onto nipple, other end blocked by soldering and a
small hole drilled in the side. the hole is covered by another piece of hose. cut off the bottom of a brake fluid button or a container with same
diameter opening and using bike inner tube attatch it to the resevoir. this increases the reservoir volume so you get more pedal strokes before
checking brake fluid is too low.
