No Front Brakes!!

1986 Yamaha Maxim X 700

1)New master cylinder rebuild kit installed.
2)All solid brake fluid cleaned from both front calipers.
3)New fluid
4)Gravity bled and pump bled.
5)No brakes.
Left caliper SHOOTS out of the bleeder.
Right caliper shots out of the bleeder (shoots, not SHOOTS)

I can "slow down" but thats about it.
I am almost 100% sure there is no air i the system.
I think I have roughly 5 hours into bleeding the brakes.
I pushed the pistons back in by hand and no tools.
Is it possible that the seals got damaged from brake cleaner????

When I got the bike I drove it home with no issues other than the front tire being bald and choppy.
When I took the wheel in to get swapped I changed the pads with the same number on the back of the pads.
Changed the fluid and I probably got some air in the lines at that time because I forgot about filling the master.

After getting the new tire and putting everything back together I went on to bleed the brakes noticing the master cylinder wasn't returning.
Upon waiting for the new rebuild kit I used my dad's master cylinder from his 83 Virgo.
That worked..... but didn't feel right (came from a single caliper bike, mine is dual)

Got my new kit and installed it.
Master works great.

I have blown through the hoses, scrapped everything out of the calipers and cleaned them with kerosene.
The seals were removed for the cleaning process.

Besides throwing more money at it buying hoses and caliper seals, what else could it be???

 

There is still air in the system.
Tie the brake lever to the grip overnight.
The next day bleed it again.
If it's still mushy, borrow a vibratory sander and use that to shake the air bubbles out. Start at the caliper and work your way up the lines to the master cylinder.
Also get new brake lines. Rubber only lasts for so long, and that's where some of your mush is coming from (the lines are expanding under pressure).

 

Stupid question , you are closing the bleed screw before you let go of the lever right?
And is the master cyl returning all the way out when you let go of the lever?

 

Yes and Yes

 

...all new crush washers when you put everything back together?

 

Or annealed the old ones (if copper)?

 

I agree that you still have air in the system. If K-moe's suggestion doesn't work for you then you can try the method I used on my 85 xj700. I got one of the large cattle syringes from Tractor Supply and about a foot of clear flexible hose and bled the calipers from the bottom up. Fill the syringe, attach the hose to the bleeder valve and slowly pump in the fluid. I started from a completely rebuilt system with no fluid in it and it took me about 15-20 minutes to complete the entire process. Did both calipers, then jiggled the brake handle to get the few remaining bubbles out of the m/c, and even though I had hard brakes at that point I did a normal bleed on each caliper just to be sure. Since you already have fluid in the system you will have to pump very slowly and keep emptying the m/c until you see no more bubbles. Make sure you see no bubbles before going to the second caliper. But hopefully K-moe's method will do the trick for you. Be sure the bike is on the center stand and the tire straight ahead.

 

Success! Thank you so much!
