Ny mate bled his with water, he opened the reservoir and pulled the brake so he could see air bubbles come to the top. Then filled the reservoir with water. Seemed to work, you can do the same with maggie oil.

to be honest buddy id wait till next wee and go to your local bike shop and getting them to bleed it for you as i have seen it first hand (sales assistant and juniour mechanic!) waht can happen when people try bleeding brakes themselves. they can loose all sorts of things, these can be replaced but its all money which could be saved. how about do what i do. go out with your mates but take you brake of untill it can get fixed so that way you can still go out and you keep your brake safe :) . works for me on my bikes when something goes wrong

Seriously just use the search bar, thats what it's there for.

Bleeding The Brakes

1 - Remove the pads.

2 - Remove the disc.

3 - Go to halfords and buy some Dot 5.1 oil and a clutch/disc bleeding kit. The are traditionally for motorbikes, but the tubing is the right size - just remove the ball bearing that's on the end of the tube. This should cost about £8 for both and you'll get LOTS of bleeds out of the oil.

4 - Push the pistons in so they are flush with the calliper.

5 - Put the tubing on the bleed nipple and get yourself a spanner for undoing this (I think it's an 8 or 10mm)

6 - Making sure your lever is parrallel with the floor (i.e flat), un do the reservoir cap.

7 - If it is fairly empty, top it up with your new oil. (tip: with halfords oil, don't remove the foil, just pierce a small hole)

8 - Undo the bleed nipple. Now pull the lever. If the pistons move, you haven't undone the bleed nipple enough. Then while the lever is pulled in, close the bleed nipple. Then let go of the lever and the vacuum will pull oil through the system.

9 - Keep repeating step 8 until the oil is running clean and no air bubbles are coming through. While repeating, periodically top up the reservoir. DO NOT let it get too shallow or it will pull air through the system. If the pistons have moved, you screwed up the routine (like pulling the lever with the nipple closed). So push the pistons back in to place before carrying on. If you screw it up enough, the piston will actually fall out. But don't worry, just put it back in place, clean up the oil and carry on.

10 - Once content that's it's bled properly, top up the reservoir and then put the cap back on.

11 - CLEAN UP. If you get oil on your pads or disc, you are gonna have a hell of a time sorting it out. So make sure you remove all oil with tissue, including near the pistons as the oil might get on the pads.

12 - Follow the disc and pad cleaning section of this guide, and then put your disc and pads back in. Line it up as centrally as you can using the washers.

13 - Keep pulling the lever and it will eventually self adjust and the pads will be in place.

14 - Fine tune the adjustment by moving washers. If it's not rubbing, it's probably not worth moving it.

except DONT use any DOT fluid in maggie disks, go and get some maggie royal blood.
