I am about to bleed my hayes 9's and have downloaded the manual but it would definately be easier if there was a picture story of how to do it? any help would be great thanks ...

Cannot help with pictures but until you are used to bleeding them take off the bike, remove the pads and make sure you protect anything from the splashes of brake fluid. Latex gloves are a good idea as is eye defense.

Other hints:

- Only the little plastic stopper is removed from the lever not the outer rubber bit
- The stick in bleed pipe for excess fluid can be a challenge to keep in place
- Clean calibers and make sure the slave pistons are fully back
- Start bleed by keeping caliber bleed valve closed, pumping the bottle to remove air
- Open valve, squeeze bottle for 5 seconds, then release. Repeat until no air bubbles seen
- Once caliber cleared of air squeeze bottle until fluid flows from lever
- Continue until no air bubbles are seen.

Everything said in the last post I 100% agree with.

Sellotape or zip ties are your friend when it comes to keeping things in place,especially the hose that goes in the master cylinder.

Make sure your lever is vertical and pointing at the ceiling,as I kinda missed that in the manual and had problems getting all the air out (unsuprisingly).

The bleed valve on the caliper can be a right sod if you let it,and you will get some fluid leak no matter what you do,so remove the wheel/pads (I have a squealy right now due to probably getting fluid on the pads/rotor after being lazy).

Above all else,(and sorry for the caps) WEAR EYE PROTECTION!!!
I got some DOT 4 in my eye while doing a bleed on Saturday when the hose pinged off the bottle,and damn does it hurt!!
Luckily it was only a tiny drop,but it's not something I want to repeat.
