With help from Tegger and others I Replaced the MC and rear pads and drums. After bleeding the hell out of the system things llok good Except! for a clicking sound that comes from both rear brakes.
I had reused the old springs and clips and I plan on going out after typing this and replace the old parts with new hardware kit. (springs and clips)
Aside from this, any suggestions on whats causing the clicking sound from the rear when the brakes are applied?
1998 Toyota corolla, NO ABSThanks

If the clicking is related to car speed, then you've got something touching the drum as it spins. You've got no choice but to pull the drum back off and inspect it.
Do you maybe have the shoes adjusted too tightly? Is there a rust-ridge around the perimeter of the drum?
Unless the hardware got damaged in some way, it's unlikely replacement of it will, by itself, eliminate the noise.
I should have said it only clicks when applying the brakes. drums and pads were replaced. I inspected both wheels and everything looks OK.
The pins holding the shoes were pretty rusty so I'm going to replace the hardware while I have the wheels off again...Then I'll test drive again. From the sound, I realy thought something had broken like one of thosepins??? but Like I said, everything looks normal. I'll watch for having the pads expanded to much..
Thanks

A clicking sound from drum brakes can be a drum that is cracked either -through- the wearing surface or cracked between the lug bolt holes. Some of the cheaply made drums having a cast iron wearing surface but a stamped steel support plate (the area where the lug nut studs pass through) will click. Nothing to do with these but replace.
I just fought a car with a similar issue; except that we has new hardware put in- Have the drum checked; get it cut if necessary. Notice the sound "clicks"? That shouldn't happen with a true drum.
I've seen new drums and discs come from the stores out of tolerance. (or perhaps in tolerance but causing an issue)
Well I put in the new hardware and checked the operation of the hand brake. The auto adjuster worked with each pull of the hand brake..Everything looked good. I used a file to champher the edges of the pads, not likely but what the hell???... I reassembled and took for a test drive. Still could hear a click, from both sides? as I stepped on the brakes. I drove around testing and trying to anilize. Then the sound went away. I went to a deserted street and did multiple stops going forward and backward and it sounded fine.
Brakes feel much better now. Could the shoes have settled in so the dont click now??? I'm hoping so...

The brake linings on drum brakes are referred to as "shoes." The linings on disc brakes are referred to as "pads."
Next time, try using genuine Toyota brake parts. You're a lot less likely to run into troubles. If the noise comes back, try putting the back of the car up on jack stands, spin the wheels, and have someone gently apply the brakes to see if you can duplicate the noise and pinpoint it more.

Like Philip says, check carefully for cracks in the drum. I never thought of that.
If you jack up the rear of the car, spin the wheels by hand, and have a helper gently apply the brakes, does that help locate the sound better?
You didn't say if this was 'one' click. or 'multiple' clicks.
My 1997 Celica brake system has always given me 'one' click the first time I use the footbrake after I initially move off - and then no more.
This especially if I backed-up prior to parking, which I normally do.
The handbrake mechanism clearly has to un-latch somehow if the car was moving backwards before braking.
The brakes work perfectly - still on all original pads at 81K miles.
