I've owned a Gunsons bleeder for decades but never us it now. You have to find a cap that will fit your reservoir, which can be hard to do.
What do you you mean by "the old fashioned way"?
I usually do my bleeding (one-man method) by fitting a small plastic non-return valve on the calliper nipple (the valves are meant for use on fish tanks and are very cheap on ebay e.g. https://www.ebay.co.uk/itm/183569274052?epid=25026751982&hash=item2abd94d4c4:g:WYUAAOSwlLlcC9RW ). As soon as you press on the pedal, the fluid flows thro the system with negligible back pressure, and the valve prevents air getting back in by closing the instant you release pressure on the pedal. Admottedly, these cheap valves don't last forever (though I put heat shrink over them and that's good). Brake systems are designed to work by having pressure on the master cylinder; never been too sure about the merits of suction systems???

Yes I’ve got a compressor, up Until now I’ve always just pumped the brake pedal to bleed the brakes, BMW master cylinders don’t like this, it knackers the seals, I found this out the hard way with my X5.
Hence why I want a pressure bleeder, also makes it easier to do it solo.

That would be the Easy Bleed kit then from Gunsons, ok but after a while the seals tend to knacker up so the pressurised cylinder just leaks. Biggest mistake most people use with these is they don't let the tyre down enough that you connect them too.
You can get hand operated suction systems but they tend to not be powerful enough for tricky systems or first time bleeds of new systems.
The compressed air suction versions are in a whole different league, they work brilliantly and I've never failed to get a perfect pedal.

haven't used one and don't know the name... but gave mechanic next door a hand once for 2 min... he used a pressure system that pushed fluid back up the system from the bleed nipple..... worked really well
no idea what other people think of them

The ones that work on a car tyre are absolute ****.
I have this one: https://www.ebay.co.uk/itm/35358558...RBRY5mxSPi&var=&widget_ver=artemis&media=COPY but not this seller.
Work really well. You can back bleed easily with it. I use it on trucks.

You sure about that knighty ? Surely that wouldn't expel the air and would just push it back up further into the system

I know it as back bleeding. Pushes it from the nipple up into the res.
I suppose it depends on the system but sometimes it’s the only way to get it all out.
Often it’s necessary to go one way, then the other, and repeat a few times

you can push up as well.
Have to do it regularly on air / hydraulic clutches on DAFs if you get air in them.
Not really very helpful to OP, but some stuff now needs to be bled via computer using ABS pump. Nissan / Renault vans is one. Can’t remember the model.

Yeh thanks James, that was one I had looked at, think I might get that one. I bought a pressure bleeder years ago which worked on tyre pressure, didn’t like it and it stopped working, unknown eBay brand, at least sealey is well proven.

I recently used a Sealey pressure bleeder, I'm now a fan

It does have the issue of needing the right cap but having used many solutions over the years including one way valves, suction bleeders, Gunson etc this one is the best yet

Coincidentally I stopped in at my Indy in Inverness yesterday morning before hospital clinic/Edinburgh visit to have the fluid changed on the E60, total invoice came to £41 odds.
At that price (Inc iDrive reset, although I could have done that myself) it seemed like a bargain for two years brake service costs....

I’m a bit of a DIY guy, and have a few cars, and my plans now that have my workshop is to be working on cars to buy and sell them as a bit of a sideline, so diy is the way for me. I don’t like paying for work I can do myself ….. and that includes house Diy, and owning a 100 year old house jeez I go to work to have a break!Coincidentally I stopped in at my Indy in Inverness yesterday morning before hospital clinic/Edinburgh visit to have the fluid changed on the E60, total invoice came to £41 odds.

I have this one too - I also bought the whole set of adapters.
Pardon our interruption...

For reverse bleeding - I use a mitivac hand pump and bottle (I only use this for bleeding clutches up with thou!)
