Re: Help to brake bleeding
You need brake fluid
Glass jar
Rubber or plastic tube
Spannner to fit bleed nipples.
Fill master cylinder with fluid, keep it topped up during the bleeding process.
Start at the wheel furthest from master cylinder, fit tube over nipple, place other end in jar ( have some fluid in jar, and keep tube end immersed) With all other wheel cylinders closed, open the furthest cylinder and pump the foot pedal, do in a few times to get the fluid moving. Once you see fluid coming from the tube, on the next swift downward stroke of the foot pedal, hold it down and tighten the bleed nipple. Raise the foot pedal, then loosen the nipple again, then brake pedal hard down again and whilst still down lock the bleed nipple again. Repeat until no bubbles appear in the jar fluid. Then move to the next wheel cylinder, ( the second furthest from the master cylinder) repeat the process on all wheels, keeping an eye on the fluid level in the master cylinder, don't let it drop too much or air will get in and spoil your work. You will need an assistant to operate the foot pedal, while you do the cylinder nipples. Don't think I've missed much, if I have someone will tell us! Good luck.
Just an additional thought, before you start, make sure your brake shoes are well adjusted, and just kissing the drums.

Re: Help to brake bleeding
Hi
Here is an excellent guide I used to get me going.

Couple of other things - Do your 1st bleed with the drums off to allow the pistons to extend and retract.
Ensure after this that your brakes are correctly adjusted up to the drum before further bleeding.
