Ed you found a nice one with no brown sugar or rocks in it.
Most of them are worse.
 
So will i need a rebuild kit?
or can i just take them apart and clean and put back together?
obviously a new kit would be better.. but i dont have the cash right now to spend on it..
 
and to take the piston out i just pull off the caliper and extend it by pumping the brake the it should pry out by hand.. if not ill need air to get it out?

That depends on what you find. You should get a rebuild kit... but if nothing is ripped and is still pliable, you may be able to get away without one. If the piston is pitted you will need a new one.

Normally, I pump the brakes until the piston pops out. But if your return port is clogged I'm not sure it will work. The other, more popular, option is air.
 
OK thanks..
I dont have air so lets hope pumping works or im gonna have to take them somewhere lol
 
Well... i cleaned the master cyl. and now i have 0 pressure.. bleeding doesnt help.. any ideas?
 
Try bleeding in stages. Bleed the mc first by leaving the hose off the MC, finger over the banjo bolt hole and pump away. - cover everything that is painted with rags as fluid will squirt everywhere. Once that's working connect the hose to the MC and disconnect at the other end and so on.
 
Okay so here we go..

first bled brakes.. no help
second cleaned master cylinder. no help
bled brakes and flushed again.. no help

popped the pistons out of the calipers..
no brown sugar or anything like that.. a little dirty fluid... cleanded the inside of the calipers and the pistons and they had stick looking stuff on the sides of them.. i took a razor blade and scraped it all off.. cleaned everything again. put on new pads and rebled everything..

and NOW.......

the bike rolls!!! with almost no pushing!!!!!
no more locked up brakes..

and you would be surprised in the power increase when you dont have the brakes on haha..

finally i get to start riding.!!!!
 
Great,

But, be careful on your 1st ride

I would have replaced that flat O ring around the pistons while I was in there
 
hey guys, similar problem on my cb900.

It's got Dual Pistons.

I rebuilt the Master, and both calipers.

Covered the hole on the MC, and I get proper pressure, but once I hook up to the lines, the fluid goes down a little bit to the calipers, BUT I just have no pressure and the Brakes are too soft, pistons won't compress.

We've tried bleeding it a million times.

Does it sound like we have air getting in somewhere still?

I've heard of people having similar problems and they HAD to use a mighty vac to suck all the air out and rebuild pressure?

It took me a long time.. but i bled the mc over and over and over.. then everything else.. then the mc again and again.. and it finally worked..
 
Not sure if it was mentioned but make sure you grease the pins lightlty on the calipers while you have eveything apart
 
Sorry to hear you dropped the bike. That sucks big time.

Did you ever tear down the master cylinder? The only way to properly clean it is to tear it down all the way, scrub it out with soap and water, and then inspect the parts and replace parts as necessary. The rubber brake lines should go in the trash; they are sure to be soft and contaminated on the inside with scale.

Please do the job right before you really get hurt.
 
Thoroughly clean out the master cylinder and brake caliper(s) with Brake Cleaner
and lubricate the internal parts with clean Brake Fluid.
Not a bad idea at all to replace the front brake lines at this time either.

Well the return port was for sure clogged.. now when i pump the brakes i get some brakefluid that shoots 6-8 inched up out of the master cylinder..

HOWEVER..

after bleeding the brakes a few times..

they still feel soft.. compared to before..

maybe they are how they should be.. but i feel they could stop me sooner.. at least they use to stop me much faster.. and i can pull the lever all the way in.
__________________
 
The lever coming all the way in could be caused by the rubber lines expanding like a balloon. There is a reason Suzuki says to replace them every two years.

It could also be air, or a problem in the calipers or the MC itself...
If the brakes are not stopping you as well as they were you still have a problem.
 
They do look like thy have been replaced recently.. but i cant be fore sure..

should i try to bleed more? or what..
 
Maybe I'm slow, did you tear down the master cylinder or not?

My suggestion is to replace the brake lines and ditch the anti-dive, which doesn't do much other than make the brakes feel spongy.
