rear caliper bleeding woes

#1 Post by fatboy » Tue May 07, 2013 6:36 pm

Tried to replace the old fluid using a vacuum bleeder but could not get an airtight seal over the bleed nipple.
Odd as I replaced the fluid on the clutch side with no problem.
Could not get it to bleed up using the kz method :smt013
So I will replace the caliper bleed nipple and fit a banjo with bleed nipple on the master, so my learned gentlemen, what sizes of banjo and bleeder do I need for 01 Falc ?

Take the caliper off without removing the tubing. Tilt it so that the nipple is at its highest and bleed it that way. two or 3 pumps and it will be right. Worked with me on mine.

Same as what paddy said.
Mine worked first time :smt003

Mmm had the caliper on top f the swing arm, bleed point highest, just would not play.
Trouble really started when I could not shut the bleed nipple before the fluid drained from resevior ( shitted up bleed nipple threads )
As i said,think the best course of action is fit banjo with bleed point and replace nipple, all available spares, if you know what size :smt012

If you've got crap threads on the nipple, the danger is you'll leak air the minute you stop the downward pump

ha, that would then explain the astonishing amount of air in the bleed pipe !
So, back to where we were, anyone know the correct size for replacement bleed nipple ?

That's the trouble with a vacuum bleeder. Putting the caliper up and bleeding the normal way should do it no problem. Pump pump, hold, release, tighten, pump, pump, hold, release, tighten, anyway enough of my bedroom talk, back to bleeding brakes........

sorry I thought I had wandered into a breast feeding class for a minute but now that I am here and this does seem to be about brakes ... and because I can't be bothered to look it up what grade of brake fluid/ :smt017 :smt001
For the avoidance of doubt and for the benefit of my wife, not everything I may say here will be absolutely true I may on ocassion embellish a little for effect.
That said when it comes to motorbikes, I like to ride side saddle with a nice frock

dot 4 or 5.1

don't mix them either


Let's face it, you wouldn't go to a nurse to get good advice on a problem with a Falco - you'd choose an Engineer or a mechanic...

Those (dot4 and 5.1) can be mixed.

Don't mix dot4 and dot5 - different chemistry .... in fact don't use dot5 on your falco.

Just use dot4 - available from everywhere and does the job fine.

As I am on nights I cannot be arsed to search but I thought some one here, or on af1 posted a really good article saying that even though they can be mixed, don't do it as it affects oil life or something

I had a big barney with KZMILLIE on AF1 because he maintained you can safely mix DOT4 or 5.1 with DOT 5 simply because he mixed the two in a jam jar and nothing happened

I remember reading some blurb explaining the differences between DOT3,4,5 and 5.1.
Although I've forgotten most of the content of what I read, I do remember DOT 5 having some weird properties, making it not everday use stuff.
Is it more race orientated, with a short working life ?

Doesn't 5 have a totally different make up to the others? Personally I run 5.1 in anything that requires brake fluid. Obviously drain it all then fill and bleed for ages and ages... Always have. No real reason why 5.1.

Have ordered new bleed nipple for rear caliper, banjo bolt with bleed nipple for rear master cyl.
Looks like getting the fluid (and air ) past the point where the brake line passes beneeth the swing arm will be the fun part. not
