Hi, I have just replaced the pads on the rear of my 05 BA XR6, however the brake pedal became very spongey I checked and found that the brake line bolt to the drivers side had come loose, must have happened when I moved the caliper up to refit the new pads, can I just bleed this one side or do I have to do all four. I have to do it myself as no-one home to help, I have a one person bleeding kit.

Thank you for reading.
