This may sound as stating the obvious, but you do know there are 2 bleed nipples for the rear brake - you did bleed both sides?

Dave - just followed your instructions with the rear brake.  Fitted some new HEL hose to match the front. Plus one on this. It's amazing how much air is purged when bleeding. Inside nipple was an endless flow of bubbles.

I did both Dave yes    it's definitely ceased with piston out now so seal replacement I'm guessing!

[gsxbarmy]

Not sure the seals will make much difference - unless they have gone hard - but could be. Easiest way to check is to take the caliper off hold one cylinder in and press on the brake lever (gently!) to check how smoothly the other piston comes out. Repeat then for the other side. They should both be the same.

I'd also:
- check that the brake pedal level itself moves smoothly on its spigot. PITA to get off with the springs on it and for the brake switch, but could be you have some grubby in there
- don't overlook the rear master cylinder and whether that is ok
- clean off the rear disc with some 1500-2000 grade wet and dry (wet) to clean off any mucky on it. Likewise I would also just take the top layer of the brake pads off with same (dry). Always possible Nigel that the brake pads have (somehow) got contaminated and now no longer grip like they used to.

I can't see it being the disc really but good luck sorting it.

Thanks Dave I'll have a look at all of that  I can see the piston on the right side stuck out and not going back in

[Paulpmy]

I have put brand nw front and rear calipars on mine nothing wrong with old ones I just wanted new t, the new back one it very good

The old calipars is up for offers if your interested

[Paulpmy]

Crack the pipe at the master cylinder , bleed here 3/4 times

Then bleed front nipple on back then back nipple

This will work

But if you have a constant flow of air it must be getting in somewhere

[Red Biker]

Thanks Paul,
They did 'seem' to bleed ok but I'll try it direct from the cylinder
