Bleeding brakes

[Wattie]

I got some new calipers for the 10,

i ripped the old ones off, undid the lines off then, and all the fluid syphoned out...

oh well, i thought.

whacked new ones on, (old pads dont fit dave)


put lines back on. filled resevior thingy,

No Go

i pumped for like 2 hours, i've got some fluid through and into a bottle, but cant get a good stream going.

i have no brakes at all. the old man suggested taking the master cyliner off and getting it positioning it below the calipers, so the fluid pumps the air upwards, but i cant gett he fecker threaded through the fairing.

any easy fixes? b4 i turn the bike upside down the get the master above the calipers??

Get a plastic tube on the open nipple dude and suck it through. Tastes a bit shitty but it works. You've got a seperate line to each caliper haven't you. Suck it through both before pumping the lever. When I did the braided lines on the 10 that worked fine.

Did you buy the ZX14 calipers off Ebay?

Get these... Or just keep at it for another hour or so..

I did mine on the 7 when I found there was silicon fluid in em and had drain the lot.
Took an hour or so then suddenly pulled up.

You can suck the fluid through, never done it myself..

you dont need brakes anyway, they just slow you down.. give me the calipers ya bastard !

im not real good at suckin, might get the mrs out there, she need some practice

yeah got the calipers off ebay Glen.

they seem pretty good, a couple of little scratches, but not bad at all.
pads are like new. same amount of meat as my week old set.

Having lost some part of the fluid through your disconnection method Wattie, it is always going to take some time to re-bleed them. When I changed the calipers on the race bike, It also took ages to bleed up to a hard lever again. I even went to the trouble of buying a suction pump to suck the fluid through. Best method is to persevere and it will eventually bleed back up. Just kep re-using the fluid until you get a lever, then run clean fluid through at the end.

Another trick which I use to get the last little bubbles out, is to tie a cable tie to the brake lever tightly pulled, overnight. Compression forces the bubbles up into the M/C and back into the air!

It works...I did it with the old 9 and I've done it on the 10. Gos did it on the sportsbarge recently and was raving about it

I've bled for ages on the TZR, bought braided hose,tied the lever overnight and hung the system from the roof and the lever is still soggy compared to the GPX. Could crud/corrosion in the caliper be responsible?

You need to bleed the master cylinder first - close the bleed nipples on the calipers, fill master cylinder with fluid then while applying pressure to the lever, crack the hose connection at the master cylinder, retighten hose then release lever. Repeat a couple of times (making sure the fluid level is still up). Then you do the calipers.

I used the suck method, took me a few sucks on each side to get the air out, then BANG!

FUCKIN ROCK HARD LEVER!!!!!!!!!!

i bled each side a few times to make sure i got it all out,

god dam i cant belive the improvement in the solidness of them!

im so happy with the result. and all this while still using the stock master cylinder!

fucking topS!

Ladies - form an orderly queue at Watties place!

Wattie - mate.......surely your missus needs practice on a hose bigger than 6mm eh ??

good to hear you got the brakes sorted, what did you upgrade to ? a set of Nissins or something ? I did the cable-tie trick last week as Mick mentioned, bloody hell the brakes are just superb now - a few of the guys on the defunct ozZX12R forum all mentioned this trick at one stage or another.......I will be doing this on all the bikes now, the lever is fully rock-solid just at the point of 'clicking' the brake switch.....

MiG - its worth stripping the calipers and checking for corrosion, it sounds like the problem needs more than bleeding to fix ?

[Wattie]

yeah i got Nissins of a ZX14.

i havent bothere witht he cable-tie trick, i used to do it on the old calipers. and ont he Z ones. works well, but this dont need it so far
