Ok, leaving the milk bottles, beer bottles and 'Casualty style' plastic tubes running from every vein to one side for a second.

Who is using a fancy gadget such as a MityVac or other brand? Which specific ones do you use and do they work well. If I'm going to fork out for one I really want it to do the job first time with no ar$ing around.

I use none, the old fashioned method is enough for me and I don't find it any slower to do.

Learn how to do it the proper old skool way and save yourself £40! The Mity vac gets the thumbs up from those who use it

whilst I use the traditional milk bottle and tube. I got one of these some years ago and it is so easyhttp://www.uktools.com/images/sea/big/VS020.V2.jpg

Yeah, perhaps I should have mentioned that this was about brake bleeding :-)

I do happily bleed brakes with tubes and bottles etc but thats only because I've never used one of these new fangled brake bleeders before. On top of that I do like buying tools :-)

90% of the time using tubes is fine but every now and then you get a dry brake line thats a pain in the backside to get started. Once its flowing through properly then no problem. I find this happens more often with the back brake perhaps due to its layout.

Only used my Mityvac once (last weekend was the first time I needed it, since I got it), have used the jam jar/old brake fluid/hosing method half a dozen times. I found the Mityvac good, mainly because so long as you keep a vacuum in it by pumping, you don't need to keep snapping the bleed nipple open/closed all the time. I couldn't get the lever any harder than I could with the traditional method, but then, I could get it hard enough to be more than adequate with that.

Mityvac for me, I have a diecast dual action version with gauge because I use it for other things (transducer calibration etc). The plastic ones are good quality industrial products, we used them in the engine test facilities in automotive industry.

Sure you can bleed brakes by a number of methods, but the continuous flow system makes it so easy to get reliable results that I find you tend to change fluid more regularly.

If you're likely to be doing brake bleeding for the forseeable future years, the cost of the mityvac will be easily justifiable.

Motrax do a more expensive version ("Big bleeder")

The only correct answer, Mityvac etc undoubtedly good quality tools but ultimately unnecessary for bleeding brakes.

Unnecessary? Yes, undoubtedly.

However, being able to push fluid up from the bottom instead of down through the system works out a lot easier for me. No faffing with cable tying the brake lever overnight either (not that I'm saying anyone else here has to).

MityVac (plastic jobby) for me.

How do you push the fluid from the bottom using the mityvac?

Mine has 2 outlets on the hand pump vacuum, one on the front, one on the top. The top one is an air outlet, the front one is an air inlet.

If you hook the inlet up to a reservoir of brake fluid (like the pot supplied with the black lid), and the outlet to the bleed nipples, then just pump by hand, and the fluid goes up through the calipers & up the hoses.

All the pipework came with mine, and it tells you how to do it in the instructions.

Ta, I'll have a look at that when I do the rear.

Just watch the brake reservoir on the bike, you don't want to push so much fluid through that it overflows! :lol:

Obvious, but worth stating IMO.

Definately. That bit of the bike is covered with wet rags whenever I work on the brakes. :)

I've had a basic plastic MityVac for about 6 or 7 years and use it about twice a week. It saves god knows how much time when bleeding new braided lines and makes changing brake fluid on any bike a 5 minute job without all the 'lever in, nip up nipple, lever out... repeat until bored' palaver.

M&P (http://www.mandp.co.uk/productsList.aspx?tier1=Braking&tier2=Bleed-kits&tier3=Mityvac) do them at the same price inc. p&p as an alternative

Big syringe is IMO far better than a Mityvac. Brake fluid in syringe, attach to bleed nipple, open nipple, push fluid into caliper till it comes out the reservoir. Repeat for other line. Sometimes repeat again- you can also use the syringe as a handy airtight catch bottle, pushing fluid back down to carry out any bubbles in the caliper. I hate bleeding brakes but I can do mine from dry lines (well, line) in about 5 minutes. And that includes finding the syringe :mrgreen: All for £1.99 off ebay.

It's well worth learning to do it the old-fashioned way but IMO there's no reason to put yourself through that when this is easier and faster, and cleaner too if you're clumsy- no bottles to kick over.

I bought a motrax little bleeder today for a tenner and it's got to be the best ten pounds I've ever spent. It certainly took a lot less time messing about than using the loosen, squeeze, tighten method. Think I'd have frozen to death without it! I like Northwind's method too. Reckon I'll get one of those.
