Brake bleeding kits

[Ant132]

Hi,

I changed the pads on my bike a few weeks ago due a spongy feeling lever and the fact they were close to the limit so i also cleaned everything up which involved replacing the fluid.

But now, even after new pads the lever still doesnt feel very firm and is quite spongy. So it must be air still in the system?

What brake bleeding kits are the best for this (cheapish though), i found this one on ebay. It says you can pop the tube on, open the bleed nipple and pump away until bled but do they really work?

Cheers, Ant

A brake bleedin' kit? Just get thee some clear plastic tube my local motorfactors sells 2 metres for £2.

What you do is pop a ring spanner on the bleed nipple, then put the plastic tube over the end of it. then put the end of the plastic tube in some brake fluid. This prevents back flow of air into the system.

Pump the brake lever a few times at the master cylinder, use a cardboard tube to hold it in, then undo the bolt. Air should come out along with some brake fluid. tighten it up then pump again and repeat. Top up the master cylinder now and again make sure you do not expose the hole to air. The bubbles should become less and less and eventually you'll hear a creaking noise this is the pistons pushing against the pads and most of the air should be out of the system.

You can actually bleed the brakes without a plastic tube at the top if you want I used to do that, but it will take a very long time.

For a bike what Itchy says is the right thing.

For a car etc I would use an "easybleed" kit.

The one that you have a link to is not the best as the second you have an air leak in the pipe you are back to square one.

You can buy Easybleed brake bleeding nipples. but they are twice the price of standard bleed nipples.

Do what Itchy says, get the knack, and from then on it`s the easiest and cheapest way.

hi,
i always find the reverse filling/bleeding method the easiest.
a metre length of washer hose & a 25ml or 50ml syringe from the chemist.
cut 6 inches of hose off the metre lenth & connect to syringe. (the remainder can be used for bleeding the way suggested above)
suck up some brake fluid from your fresh bottle of brake fluid.
connect the syringe/pipe to the bleed nipple.
loosen off nipple & "inject" the brake fliud up.(this will also shove any trapped air up into the reservoir)
simples.
cheers,
GAZ

I have a little piece of rubber tubing with a bung in the end and a slit in it. Allows fluid out of the slit but nothing back in.

I have the same kit adverticed on Ebay i got it in Halfords for about £5. I works amazingly well. You loosen of the bleed "niple" (Gigady) attach the tube and pull your leaver a few times and its all over.

A tip for the sponge feeling your getting now is just keep pulling the lever and it should stiffin up.

I did this on a YZ 250 and worked

Agree with above I have tried various 'kits' and nothing works better than a bit of clear tube and a pickle jar.
