If there is no button, it is not a problem. It will bleed fine.
What you have is the distribution block with a warning sensor.
All it does is basically 'T' off the lines from the master, and provide a warning switch to trip the brake light if there is failure.
The different valves are not necessary for the system to function.
They are primarily for slippery conditions, better pad life, and panic stops. (it makes it more safe)
I still think the 1/4" line goes to the rear brakes, but I cant always be right.
Make sure you know which resivoir goes to which brakes.
You wont be able to tell by the fitting sizes because masters dont always take the standard store-bought sizes that come on the tubes.
Here are some common fitting sizes: (diameter X thread count for tube size)
3/8x24 for 3/16 tube (standard; comes on store-bought tube)
7/16x24 for 3/16 tube
1/2x20 for 3/16 tube
9/16x18 for 3/16 tube
7/16x24 for 1/4" tube (standard; comes on storebought tube)
1/2x20 for 1/4" tube
9/16x18 for 1/4" tube
1/2x20 for 5/16" tube (standard)
you can see pictures of these fittings and some other quasi-accurate info @ inlinetube.com
You can just use adapters if you get the right ones.
Don't worry about the valves for now. You could even just get a 'T' off the master for the front brakes, and run the rear straigfht to the master, eliminating the block completely.
