Hey guys 5 hours later and I need help please?

I didn't find taking the caliper apart to be hard, complicated, or difficult at all. That was the easy part of my problem.

Go to cBug's website and download the manuals if you haven't got them yet. There is a little diagram in there of where everything goes in case you can't remember.

It was a really simple process, just pull the piston out, spray everything with cleaner and rub with a stiff brush, reassemble and then do your bleeding.

That being said, update your profile with a location, then someone close might be able to chime in.

I have the same bike. I taped a piece of wood behind the brake lever so i couldn't over pull it. Then took slow full strokes on the handle. I use a bottle with fluid in it, and a hose submerged in it. I squeeze the handle, loosen the bleeder, close the bleeder, and pump a few times, and repeat.It allways works great for me. I think the long slow strokes is what does it. (That's what she said i think).

Didn't see it mentioned, but get a Mity Vac for $20 at HF.

I wish they were that cheap! Try $40...

$30 at my local autozone. However, if you are having trouble bench bleeding the MC, this isn't going to help at all. It sounds like you know how to bleed, but may be having some problem in the MC that needs fixin'.

They go on sale. Maybe he could try the old oiler can pump trick that someone recently mentioned for a reverse bleed?

Tried that too.

I think I may just need a good cleaning and rebuild. Something is up with the MC.

[bikerphil]

OK, did you try teflon tape on the bleeder screw so it doesn't suck air?

no didn't do that but, I have the problem all the way up at the MC its self. Using just my finger at the hose end I can control the air suction.

[DGXSER]

So, you can remove the brake hose form the end of the MC and pull the lever and get pressure gainst your finger? If not, then put finger over this hole and pump hand lever, pressure will build until you can not hold your finger there any more. At that point, slide your finger off while putting the hose back on without losing the prime on the MC.

When I bleed brakes, I take a small can/jar and put some clean brake fluid in it about 1" up than take a hose from the bleeder to the can with a loop above the bleeder for a liquid lock. This way, when you pump air out, it goes out the hose, but the brake fluid will form that liquid lock and you will not suck air back into the system.

You said you haven't disassembled the master right?
Well you need to do that to clean the master thoroughly.As has been stated those four holes at the end of the piston that have the little reed type valve
over them need to be cleaned out.
Also if the master hasn't been all the way
disassembled there is probably jelled up brake fluid gunk in there too.
Another thing, the spooge hole may still be plugged.Were you able to get the plastic reservoir off the master cylinder?Under there is where the spooge hole is.

Bleeding brakes

No joke I spent 5 hours trying to prime my front master brake cylinder. I just did it a few days ago and after a few pumps of the hand brake, I was able to bleed the calipers. Now I pump and Pump and pump and so on, NOTHING.

The oil level stays the same. If I place my finger on the bleeder I can feel a push pull pulsation. What should I do?

Please chime in...

Use vacuume to pull brake fluid to bleeder.Use old fuel line ect. slide over bleeder use a hypodermic needle like one used to measure animal medication,slide other end of fuel line over hype without needle of coarse and pull handle up on hype. Vacuume pulls fliud though entire system.

Do I need to pump the brake handle while doing this?

[DiverRay]

No, the fluid will be pulled through the system. You DO need a CLEAN master cyl, though. I ALWAYS bench bleed the master before I put it back on a vehicle. This applies to ALL types of vehicles, cars, bikes, etc.
Keep a CLOSE eye on the fluid level if you use a vacuum tool. you will be amazed at how fast the fluid level will drop.
