brake trouble
HI all,
As with the title, I'm having trouble with my bonneville.
The brakes all of a sudden stopped working. At least the passenger side.
I pulled off both rear tires, and I can spin the drum on the driver side but not the passenger side.
I checked the passenger side brake cylinder and it'* not leaking. I can see it push forward and then it releases.
I tried checkign the front piston, but I don't have the right allen wrench.
Anybody knows what size it is? 8mm is too small and 10mm is too big.
Also the only place I see brake fluid is on the master cylinder where it connects to the reservoir.
Any idea what my problem might be? is the the master cylinder again? this would be the 3rd time I'm replacing it in 2 years. the last time, I went to Napa and got one of theirs.
Thanks
G

Forgot to mention, yesterday when this first happened, I checked the fluid and it was empty. so I topped it off today.
Of course, it'* come down a little.

its got to be going somewhere, sometimes it helps to have someone pump them while you look for fluid. you could put down clean cardboard and look for spots

I think the front caliper is 3/8" allen.
Hope the master cylinder isn't leaking into the booster. Or is that not possible?
