bleeding the back brake

Like many of the Coventry makes, Triumph had their roots in the bicycle industry, beginning motorcycle production in 1902.

Hi guys I'm having trouble bleeding my back brake ( 78 T140E ) brake was fine b4 only i thought I'd put some fresh fluid in but now i can hear a squishy sound coming from the piston which is pushed in when braking and i can't get any sort of brake feel at al, it's very soft,there is no brake fluid coming out or leaking as far as i can see, I've gone through about 200mls so far trying to get the air out but it keeps on bubbling, the master Cly has been rebuilt so i don't think this is the problem or could it? should i keep pumping away ? oh i'm using dot 4 fluid

Did you swing the caliper and carrier plate down first (underslung caliper models to '79) by pulling the wheel spindle/axle out far enough to allow the rear of the carrier plate to drop out of position (this procedure is in the factory manual) as the caliper must be turned so that the bleed nipple is at the top-before any attempt is made to bleed the brake, otherwise air will be trapped inside the caliper.
