Had to change to right rear due to bleeder screw/valve failed. Is it always neccessary to change both? My manual stated to change both. Hell, I only had 32k miles on the car. Been a few weeks and brakes feel fine.
Unless your bleeder screw stripped the caliper casting or galled the seat, all you have to do is clean up the threads and install a new bleeder screw.
The shop manual recommends replacing in pairs under the assumption that a wear-related failure will affect both sides. If you just cracked off the bleeder screw, or something like that, you'll be fine doing only one side.
Thanks Dave...that's what I assumed. The Bleeder screw was badly damaged. Must have been there from when I bought the car. I noticed it when changing the rotors out last summer and the brake pedal has not been firm since. Now it's firm.
