Help bleeding this type of hydraulic caliper.

[ArKaTxU]

Hi.
I want to put this hydraulic caliper to my original inboard disk brake but is the first time that i bleed something like this.
I have this caliper from Foxy (from LCGB forum):



The black allen screw have a small ball inside.

Thanks!

i wouldnt bother, i have some experiance at working for a small m/c dealership allbe it a fair few yrs ago and we fitted these to anything that was hard to bleed
you need to check what thread pitch you have though

OK, thanks Shocky, i know this bleed nipples but i like this hydraulic caliper because can use it with original disk brake I-cap and i think that if i put this bleed nipple there is no space to put the I-cap

true you will have to fit it and lie the hub on the floor or flat surface with the bled nipple upermost or stood up with it at the top or slightly lent over and try and bleed it that way id use dot 5 fluid so it doesnt wreck the paint

Seems difficult for me
Probably the best way is to buy another bleed nipple if someone dont tell me another solution.
Do you know if DOT4 fluid wreck the paint? because i have this one.
Thanks.

yes, it will

you can do it not fitted but you will need to clamp it somehow and stop the piston popping out we used to have a cradle that the calliper slotted into so the piston only pushed out a little way and plate acted as the disc between the 2 pistons clearly you only have one bit the principle the same i made one for my dragster couse the bleed nipple is low on those its best with 2 .. you may be able to get a nipple to fit that but you need to know the thread size a proper nipple allows you to put a small hose on there and flow the oil away from the pads and hub which is always a good idea

im guessing the allen screw IS the bleed device, i would arrange it so the allen screw faces uppermost and bleed as normal but without a pipe.. taking care not to spill brake fluid everywhere..

altrernatively
its not perfect but you can bleed them through the banjo..

arrange it so the banjo faces up.
pull the lever in
slacken the banjo a little causing fluid to escape through the slightly looose banjo.
tighten the banjo
release the lever.

repeat until there is no sponginess when applying the brake
