Bleeding rear caliper.
« on: 12 July 2016, 07:10:56 pm »
Right guys I'm seriously in the shit, I acquired a 1000 bluespot caliper and put in onto my 600 but I've tried bleeding it but I've got nowhere, so I'm looking for some urgent help to get it to work, from you guys in the know of these calupers, is there something I'm missing? I thought straight swap and bleed job done but no way would it slow me down nevermind stop me if needed.
Your help would be very much appreciated,
Thanks.

The rear brake calliper has 2 bleed nipples have you bled through both?

start with the nipple nearest the blue spot?

pump the brake lever down, open the nipple, close the nipple and release the lever................ carry on until you have fluid coming through then do the nipple to the back, then once you have fluid coming through repeat until all the air bubbles have gone but be careful not the drain your reservoir empty or you will have to do it all again!!!

Alternatively, use a big syringe to draw the fluid through the caliper. can be quite awkward if doing it on your own but pull the syringe, open the nipple and press the lever then close the nipple and repeat.

If your anywhere near Leeds id be happy to help

Done the outside one then I noticed inside one, didn't notice as I put it on as I got it all with bracket etc so just bolted it all on.

So yes I bled the outside one then onto the inner one, kept topping up fluid in reservoir and was getting fluid through both nipples, couldn't see any air bubbles so I gave it a try, nothing :(
So I stripped out the pads and checked pistons were moving, all good there and clean.
I'm at a total loss as to what's up.

I'm in Glasgow so couldn't get to Leeds but appreciate the offer.

Right, had a beer and a thought.....
So went out and started again, doing front then rear then front then rear, top up fluid and do that all over again, it must sure work now?
YES IT FOCCIN DID :) :) :)
Thanks for your help, maybe 8 just had to keep going as maybe didn't clear out all the air the first time.

Again thanks, can always rely on foccers to help when in a crisis :thumbup

Cant beat a good "crisis" then realising it wasnt so bad 7 theres plenty of us who have been through the bleeding bleeding brake process!
Its amazing how manuals like Haynes never mention the real world difficulties we diehard self maintainers of our Fazers have to suffer :eek [size=78%] but its great when it all comes right![/size] :lol

Another good tip is hang a weight on rear brake pedal and leave overnight, because its under pressure forces air out, I always bleed till I get some sort of pedal/lever then leave overnight with weight, to do front just tie lever to bar with tiestrap (also use this on ferries to stop bike moving, just make sure you got snips or a means of cutting it off)  :)

Good idea :thumbup
I use a wee strap that has a sort of locking mechanism and easy to release when I do my front ones, also great for checking brake lights too. (don't need snips to remove and can use it over and over again)
Couldn't figure out how to do rear pedal but thought maybe using said strap with a couple of bricks hanging from pedal.
