Brake ?

I broke the rear brake line on the Turd.
When the rear brake is out of brake fluid, shoud that affect the front brakes?
The bleeder valves on the front rotors are broken. I has some but very little brakes when the rear line was broken. Should I have full front brakes with the rear line leaking? If so then there must be air in the front brakes. I will get new calipers for the front.
I broke a bleeder in the in one rear wheel cylinder. My easy-out broke off and plugged the bleeder so I blead it by opening the brake line to the wheel cylinder. I will get a new wheel cylinder, do I have to replace both sides or can I replace just one?
After bleeding the at the brake line, I have brakes.

the broken line will suck in air and screw up the front brakes after a while. you should be fine replacing one cylinder.
