Im used to the method of bleeding where you use the lever to pump the fluid through ,exiting through a long tube and into a pot.
Works fine but apparently not the best way or quickest way to do it.The specific bleed kits force the fluid through and expelling air out.I'd like to give this a try to see if it works better for me but the usual cost of these things is about twenty five odd quid.£25 For a syringe, a couple of tubes and a plastic bottle seems a wee bit over priced to me :?

Then i spotted this on ebay and wondered what you all thought about it :?
Better price thats for sure :D

A guy who I work with employs a similar method fr bleeding his Hopes, i.e. using a big syringe and forcing fluid up from the bleed nipple through to the master cylinder. He reckon it is a lot quicker and less hit and miss. His wife gets the syringes from work so even cheaper.

I got a load of 4mm Aquarium tubing off the bay the other week for next to nothing for 2 metres.

I've been using the back bleeding method for several years now. All you need is a big plastic syringe and a bit of soft flexible plastic tubing as already stated.

Forcing the new fluid in through the bleed nipple at the caliper end is a much quicker and much more effective than patiently pouring in a bit of fluid at the master cylinder, pulling in the lever, opening the bleed nipple, closing the bleed nipple, repeat, repeat, etc, etc.

It does generally require a bit more brake fluid, and can get a bit messy if you get a bit heavy handed with the syringe.

Seen a few homemade bleed kits made out of a plastic syringe and some aquarium tubing. They work well apparently. Might have a go myself as I'm doing the lever pumping method as well. I'm buggered if I'm going to pay Avid £30 for £2 worth of tubing and syringes and little bottle of brake fluid.

based in this pic is how i bleed my brakes

that bottle i hold up so the fluid flows down
before inserting i squeeze it so it 'sucks' air out
oil flow in
not ideal for replacing the fluid but simple for bleeds
let me know if it doesnt make sense

I managed to find connectors to fit Avid Juicy:

http://stores.ebay.co.uk/fephydraulics/ ... =238154892

shove a small o-ring on them, fit and seal perfectly...........couple of horse syringes from t'local vets, and some tubing, sorted!

I'm going to see if I can find some aquarium connectors to fit Formula levers (reservoir screw is in line with piston, rather than perpendicular like Avids).

As above, 150mm surringe from the vets about £2 and 5mm clear washer hose £1.20 a metre.
I force the fluid up through the nipple, started doing it ages ago on motorbikes works just as well on Hopes :D

Would these fit Elixirs as well then? Don't see why they wouldn't but best to ask innit.

Looking at the Avid manuals, they'd do for Elixir as well........
