Bleeding the brakes on a z750 (probably the same on the z100

[Benjamin]

Anyone here know how to bleed brakes on the z750?

I have never had the chance to bleed brakes on my bikes before so yeah complete n00b

1. Buy clear plastic hose from bunnings

2. Connect hose to bleeding nipple

3. Open the oil container and put enough brake oil

4. Press the brake HARD

5. Using a spanner unscrew the bleeding screw A BIT until oil comes through. Keep pressing the brake.

6. Keep pressing the brake, then screw the nipple tight again. Then release brake.

7. Repeat process 4-6 until happy...

Imagine this as "pumping ... "

here ya go...........
needed....
1 new container of brake fluid* (a litre bottle should be fine for a bike)
a piece of clear plastic tube 30-40cm long to fit over bleed nipples
a small container for used fluid ( an old margarine container is good)
10mm spanner ..for nipples (check the size for yours)

1) clean around the top of the master cylinder with paper towel
after getting the master cylinder level ..move the bars to do so
2) remove top of master cylinder..check fluid level is ok
3) fit tube up to bleed nipple and other end into marg container
4) slowly loosen bleed nipple as you squeeze the brake lever
and fluid (probably dark and yuck) should start to flow out tube
5) as the lever gets close to the bar, close bleed nipple
6) repeat until clear fluid comes out the tube
7) keep an eye on the level in the master cylinder as you do this
- do not let it drop too far (you may have to top it up a few times)
8 ) repeat on other front caliper (same goes for rear caliper)
9) if the system on your bike has an unequal length of hose
to each caliper or one caliper gets its fluid from another one
do the one furthest from the master cylinder first
10) top up master cylinder to correct level and refit the top.
11) watch the fluid does not splash as you refill or as you bleed
- if it does put paper towel over the top of and around the master cylinder
12) if you get some fluid on the paint work do NOT wipe off
- wash it off immediately with water. if you get some on your hands
wipe with paper towel (it will wash off when you are done)
13) recheck fluid level and that you have tightened the nipples up
14) check the brake lever is firm in your hand (under your foot)
after you are done.
14) if you have calipers with 2 bleed nipples, do the one the furthest
away from the hose connection or the highest one (air in the system rises)
15) if you are fitting brake pads as well, replace them before you do the
brake fluid flush/bleed

* buy the best you can..brand is not the important ..Castrol Motul whatever
but it must be at least Dot 4 spec and yes, you can the stuff cars use
(again at least Dot4 spec)

oh..the ID of the clear tube? 4mm I think...ummm might be 6mm
mate stick a ruler across the bleed nipple, I forget
and the tube?
from Bunnings Repco or Clark rubber or bigger auto parts shops

and you will end up with maybe 300-400 ml of used fluid
in my case, i tip it into the other used oils I recycle at the council
otherwise into an used sauce/vinegar bottle container and into the
rubbish but NEVER into an old drink bottle (kids are known to drink
anything in an old Lemonade or Coke bottle they find)


hth

cheers

If you are replacing the old fluid Get a cerynge, umm seringe (How ever you spell it) suck up all the old fluid in the master cylinder and replace it with the new stuff.. The nkeep bleeding your brakes until the colour changes from the old shit (Dark) to the newer stuff usually clear or lightly coloured.
Make sure you do both the calipers on the front!
