bleeding brakes, fluid level
 

Should the fluid be filled to the just below the upper level before the diaphram is put in? or put the diaphram in then fill it?

I filled it then put the diaphram in and it looks like it might over flow

cheers

should the diaphram have any fluid in it?

sorry for the noob Qs

Re: bleeding brakes, fluid level
 

Make sure you push the diaphram in on it's self so its all folded back together and if your worried put a rag around the top while you fasten down the lid.

It might be worth holding the bike upright to do it as there will be less chance of spilling fluid out of the res. Oh and yes top the fluid up to the upper line and then fit the diaphram and lid

Re: bleeding brakes, fluid level
 

so abit of overflow is ok when inserting the diaphram?

Re: bleeding brakes, fluid level
 

Well if it's topped up to the upper line it shouldn't really overflow as it allows for the diaphram?
Maybe take a little bit out but don't worry about it too much. As for fluid inside the diaphram empty it out before you fit it just to be sure.

Re: bleeding brakes, fluid level
 

You don't want that to happen, it's horrid stuff, if it happens you've put a bit too much in. As long as the level is between the lines when it's back together you're set.

Fill to the upper level. Make sure the bars are in a position so as the fluid in the reservoir is level. Fully collapse the diaphragm and insert. The diaphragm should be just not touching the fluid. Overflow is not good. Brake and clutch fluid does horrible things to surfaces if not cleaned off straight away.

There should be no fluid in the diaphragm at all. The diaphragm will expand as the fluid drops as the brake pads wear out. The idea being no air is sucked into the braking system when the fluid gets low when going over bumps and such.

thanks, but it will defo over flow if I put the diaphram in all the way. it is filled to about 3/4 way between lower and uppser. guess I should take some out?

+1
That's what I meant to say :p :D

Re: bleeding brakes, fluid level
 

You have overfilled or the diaphragm is not fully collapsed. One of the two. Or the fluid is not level in the reservoir.

you are the man Si!! :smt038

thanks alot!

Re: bleeding brakes, fluid level
 

eh em LOL :p I suppose I got the rest wrong like :D

Re: bleeding brakes, fluid level
 

It's all to do with presentation you know. :wink:

Re: bleeding brakes, fluid level
 

thanks both of you!! ;) I didnt understand push it in on itself, but understood colapse!!

I got abit of fluid on the caliper, its so hard to get off... what should i use?

Re: bleeding brakes, fluid level
 

no worries, bit of brake cleaner sorted it nicely :)

Re: bleeding brakes, fluid level
 

hehe. I'm only young that's my excuse.

Brake Cleaner or lots of soapy water. Make sure you test your brakes before you go for a proper ride

Re: bleeding brakes, fluid level
 

Fluid on the calliper is not as awful as fluid on paint etc. Clean with a rag or indeed brake cleaner as you have done.

Re: bleeding brakes, fluid level
 

did mine the other day whole loads different its awsome, bike stops now haha, i would offer you advice but looks like you have everything you need now :D
