Gunsons don't recommend high pressure;they do recommend dropping the tyre pressure in the spare before you use it.Our garage used a can suspended about 6 feet above a car connected to the master cylinder lid.I've also heard good reports of vacuum guns connected to the bleed valve(jar fitted between valve and gun.)

I've had a Gunsons eazibleed for several years.
It doesn't suit every car on the road as the adaptor top used in place of the master cylinder cap has to form an airtight seal at about 15psi, and not every car has a screw cap and one of my family's cars had an odd cap size that didn't fit, blowed if i can remember which though.
Its big benefit to me was after syphoning out the old fluid before starting the job, you could see the change in colour at each slave as the fresh fluid came through the transparent drain pipe.

gb,
Presumably, one of the main advantages of the Gunsons gadget is it makes bleeding a one-man job?

I like my Ezibleed as well. For pressure I use the trailer (10" wheel); it's easier to get to than the car spare wheels and easier to hoick about.

I prefer to leave the old fluid in and let it wash the gunge out as it travels down the brake system.

IIT,
Yes its an easy one man job, saves any embarrasement as you call to SWMBO...up....down...up....down...hold it there...etc..
Hawkeye,
I only syphon out the reservoir and then refill with fresh, so we are doing the same thing, as usual i didn't explain clearly..
I too keep an old tyre/wheel lying around for the job, the rest of the time it weighs down a tarp covering the boxes of tools etc i may need one day..
..;)

Exactly GB......she has earned the title "mrs pumpy pumpy" hence the need for a one man jobie.
Can these bleeders not be used with an air compressor with the pressure regulated down to suit the job?
I presently use the jam jar method but find it can get messy.

Thought we'd crossed into a Steptoe plot there for a moment with little bleeders..;)
There's nothing to stop you using your compressor tank once up to 15psi and turned off, i shouldn't want it running though and risk going overpressure splitting the brake cyl reservoir, sods law dictating it will squirt the entire contents straight into your eye.

I have used the Gunson bleeder for years with great success, but always with cars without ABS. Would it still work OK with ABS?

A bit expensive?
I too use the simple one where there is a pipe with a one-way ball valve that you put into a large clear jar (such as pickled onion jar)
I think it is a clone of a Gunsons one man kit.
After sucking out and refilling the reservoir, I pump the brake slowly 10 times, while holding onto the steering wheel and hanging out the car door looking underneath watching the fluid squirt into the jar. The first time you do it you need to be careful that the reservoir doesn't run dry and soon get the hang of how many pumps you can do safely without topping up.
I can do a car's brakes in 15 minutes while smoking a cigar without jacking up in summer. Also, when you pour the new fluid in, be very careful not to entrain air as it pours, it holds tiny air bubbles very well without them floating to the surface they just seem to hang around in the fluid and would get bled down into the system. Pour the old fluid into another jar to see what I mean.

Yes, worked fine on all our MB 124's and they were all ABS.

My Gunsons will not fit the Yaris master cylinder so I used the old fashioned way with a rubber tube and a one way valve and manual pumping. BUT I wedge the brake pedal down with a stick which is kept in place by the front seat.
Works perfectly well with no problems. (I have done this since I started DIY on hydraulic systems with a 1954 Rover P4 75, in the mists of antiquity).
Yaris has ABS.
What I did do when changing the disks though, was to clamp each flexible hose, and open bleed valves and then gently push back the disk pistons with a clamp to avoid fluid reverse flowing through the master cylinder and possibly inverting the cylinder seals ( new cylinder job).
Again dead easy.
For other cars - 106.. Gunsons works fine.

Bought an Gunson Eezibleed today, darling daugters had topped their Fiat Grand Punto brakes up with water thought it was the washers but knew something was wrong when they only got a bit in and washers empty. O don't I just love them, it was dark when they did it and I always do it so it's my fault ?
Anyway managed to get lot's of fliud and water out with a oral medication sringe I got from work very handy. Then on with eezibleed with no fluid in to test for air leaks not good, leaked from where little union goes into plastic top that goes on reservoir tried tightening but gave up in end and went back to old pipe with little valve on the end very cheap tried and tested.
Then it was the clutch as it uses the same reservoir that was dead easy had to take the wheels off for brakes.
I've not given up with the gunson just need more time to get the air leaks sorted.
I was out side and it was raining a bit

I have used various bleed systems over the last 20yrs or so but they can be messy if you can't get a good seal. I reverted back to 'jar and tube' some years ago.
It is an easy 'one man' job. Cut a peice of wood to fit between seat and depressed pedal, you can adjust the seat to suit. Put fluid in the jar and open the valve until some comes out of the slave. Put the end of the pipe in the fluid, pump the pedal about 5 times and hold it down on the last pump with the wood. Tighten the bleed valve. Repeat on all wheels. To make things easier I use a well cleaned and dried glass jar. I leave the lid on and puncture it to suit the pipe. I also wrap some thin welding rod round the neck and fasion it into a hook which you can hang on any convenient spot near the valve. Result...no wife induced rage when she doesn't understand what you want her to do.
