BLEEDING

[Sabre Brian]

Some of you may have been following the issue I have had with my rear brake in the other thread.  Well I got it back from Two Wheel Tyres and apparently they couldn't bleed the brakes.  He was waffling on about how the master cylinder is lower than the caliper and blah blah blah.  He told me to hold the brake lever down overnight when I got it home and that would fix it.  I have done that but I have my doubts.

Can someone tell me is there some magic Ducati secret to bleeding.

I would also like to point out that my ignition key was bent.  I said to the mechanic, what's the go with this?  His response.

"Dunno mate - We just hang em on a hook" 

Last visit to you except to get my brakes bled properly you cowboys.

I went and bought myself a mityvac from here

Takes all the four letter words outta bleeding. Never had a problem with air after using.

I have had tyres installed there because they're cheap and never had a problem. One time I did go there and they had a 800 Monster for sale. One of the so called mechanics, an older guy, asked me to ride my bike in to put the new tyre on (Monster 1000ie) I pull in and he had this look of disdain on his face.
"What's the matter with your bike?"
"What do you mean?"
"Sounds like its about to explode."
"Ah. That would be the dry clutch. They rattle a bit."
"Our Monster over there doesn't sound like that"
"That's because your Monster has a wet clutch mate."
"Oh..."

Yeh I would never go there for mechanical work. Cheap tyres only.

Unfortunately mine broke just near there and when I rang team Moto they told me I had no warranty so I just went to the nearest I could.

Me personally would never let Team Moto touch my bike either. Speedy's at Sumner Park will take care of you. Got a mate with a ute?

... simple, cheap, effective.

the biggest issue with bleeding that rear is the nipple faces down, hard to get the air out as it sits in a pocket above the bleed nipple.
the best way to bleed it is to remove the caliper and sit it on top of the disc so the nipple points upwards, 5 minute job from there, of course, IIRC the hose is captured with the speedo sensor making it difficult, you also need to remove the wheel for access.
The mityvac is ok but i have one and never had much success with it on the rear, don't use too much vacuum with it either, it aerates the fluid compounding your problem.

did you get my PM by the way???

[Sabre Brian]

Loony yes I did mate - It is sitting there in my email inbox but every time I have noticed it was an unsuitable time to call mate.

Really appreciate it though and will be in touch soon.

I think I will just take it back to the peanuts and make them fix it.

I have every intention of using Speedy by the way.  I even have them on Facebook.  As for the ute, I own a WB, but there were a few circumstances that led me to TWT.

i usuaully just reverse bleed by a method muc the same as

[Sabre Brian]

So you just force feed the fluid back up through the bleeder?

And it doesn't have any form of one way valve in the entire systerm?

[garryc]

all i do is empty the master cylinder so that there is space for the injected fluid.
crack the bleeder fit syringe and hose to bleeder and inject until i have fluid in master.
when i have fluid in master, top it up replace cap and pump up pressure
don't know if this correct but has worked  for me.

It definitely sounds like it is worth a shot.  I went for a ride over Mt Glorious this morning with my wife on the back and after doing a couple hundred kms, it actually has a bit of pedal now.  Seems to have improved.  Probably not quite what I would call good enough.  It would not pull me up in an emergency that's for sure, so I might give your way a go and see how I go Garry because I do tend to use my back brakes a bit.

i'd be concerned that the issue which caused the initial problem is still there and that it will possibly happen again if it's not fixed.  not being able to bleed is a symptom of the adjustment/blocked compensating port issue.

[Sabre Brian]

Everything is new now Brad.  New brake line, new disk and new calipers.  The master cylinder is the same as the old though.  Are you saying you think it might have been the master cylinder that caused my problem in the first place?

[ducmeister]

Had a master cylinder issue a couple of years back where the master cylinder seized.  The first I knew of it was when I pushed on the pedal and it didn't come back up but it appeared to have been dragging just a bit for a while as the rear pads and disc were worn significantly even though I don't use the rear brake much.

Is it possible that your rear brake has been doing a similar thing?  The extra load of riding 2 up may have masked it just enough.

Just a thought.

yes, that or the adjustment thereof.  there was something wrong with the bike that caused this to happen.  best to try to find it.
