My chevy silverado rear brakes have single calipers (plungers ?). I replaced the pads and rotor on the left rear (this is the wheel that came off as I was driving 57 mph). My plunger was leaking before I torqued it back in with a 'C' clamp. I lost a fair amount of brake fluid on the ground. My brakes are on, I put the wheel back on and when I drive it, I have brakes but the pedal goes down close to the floor when I brake. It stops me all the way and I have room to stick my left toes under the brake pedal when I am completely stopped. So I need to bleed this rear brake. I can't find a bleeder valve on the caliper.
