Morning all,

I am looking for a small compressor for use in the garage for odd jobs. One of those odd jobs is bleeding brakes. Would I be ok using this Hyundai 24l compressor with a max psi of 100psi:

...with something like this Sealey brake bleeder which recommends a usage of 90-120psi or am I cutting it a little close?

The one possible issue with vacuum bleeders is that the bleed nipple seal is on the cone, which you have lifted off it's seat to bleed, so the vacuum can suck in bubbles of air through the nipple thread and give the false impression of air in the system.

As above, a 20+ year user of the eezibleed & it has been excellent especially when used in combination with the brake pedal for added volume/speed.

Another eezybleed user here, and as long as you lower the pressure of the tyre it's connected to, to the correct low level, it works fine.

Also use a Mitty vac type vac pump to bleed brakes, works ok.

I have exactly that setup in my garage, the little Hyundai silent compressors are very good if you're not aiming to run large air tools etc. (who does in the days of Lithium batteries) or run a spray gun.

The Sealey vacuum bleed and their copies work very well, you're only trying to pull a mild vacuum constantly to get a good bleed so you don't need crazy amounts of air, the Hyundai compressor is sufficent that when it starts running there is sufficent air to continuously bleed.

As mentioned you can pull air in around the bleed nipples, however this doesn't matter as when using a vacuum bleeder you should be bleeding based on quantity of fluid pulled through the system not if the lines have bubbles in them or not. If you really want to seal the nipples a quick wipe around of thick grease will do it or just turn the vacuum down by dropping the air pressure. Remember as well that bleeding with a vac bleeder is not like bleeding with a pressurised reservoir system, on a vac bleeder you'll use the hook on the handle to hold the trigger pulled and leave it on the caliper for a couple of minutes while it pulls the required amount of fluid through rather than it being a quick open and close job.

Thanks for the responses guys. I should have added that I'd be looking to do motorbike brakes along with cars so althoough the eezybleed looks good its not usable with bikes.

poppopbangbang thanks for your reply. I'm pleased to hear you have the same setup and can run it consistently with the pressures set accordingly. Any other hints, tips or observations you've made while using the Hyundai compressor? I understand its limitations and I wont be using it to run air tools.

I have the hyundai as well, it managed a leak down test ok but the shut off and restart point could be closer.
100psi shut off then doesn't restart till close to 80psi from memory. Not sure if this is adjustable??

FYI - they do an EeziBleed Pro which uses a PCL connector

Spendy though, bloody hell.

Wonder if you could replicate a Schraeder to PCL then you could use a standard Eezibleed.

Last couple of occasions I've tried my eezi bleed I've struggled to get any pressure at the caliper bleed nipples.
Even bought a spare to try.
Set at 18 psi, no leaks.
Yesterday was a 2010 Audi A3, had to resort to 2 man bleeding to get the pedal back after a caliper change.
Any ideas why this is happening?

Kinked/blocked hose.

Basically, if there is 20 psi air in the reservoir that pressurises the fluid at 20 psi & when you open the nipple fluid comes out at 20 psi, couldn't be easier unless the brake pedal is down as that closes off the inlet from the reservoir to the master.

Hi - what I mean is you need a diagnostic tool to bleed the brakes as the ABS valve block needs to be activated.

I have never had, needed, or used one personally.
