No brakes

[Romahomepete]

Changed the rea shoes and cylinders yesterday.
I can bleed one side but not the other (I did one side at a time and bled the first side before I started on the second).  I cannot get any pressure on the pedal although I havrent let the fluid level drop and all I get at the wheel cylinder is a dribble.
Anyone got any sufggestions?

Load valve?

When that happens I blame the load limiting valve for not being open enough for the fluid to get through.  You will probably know its mounted on the rear sub frame behind the drivers side wheel  and stops the rear wheels skidding when lightly loaded. Alter the position by lifting the lever up or down.
If you have ABS you wont have a valve.
Us a pressure bleeder powered by the air from the spare wheel or wherever about 20 lbs per inch .   Try bleeding with the front uphill and start with the drivers rear and then the passenger rear followed by the drivers front and passenger front .
Its a diagonal brake circuit.

That is what I thought at first but there is no resistance to the pedal, it goes straight to the floor and isnt the load valve a PITA to get at!!!

Might be that taking the pedal to its full stroke has upset a seal in the master cylinder, but a decent air lock will do the same. Well worth, as already suggested, using an Eezibleed, as it does the job without the need to use the pedal, but you can also give it a further boost by pushing the pedal. Even when I've clamped off the rear flexi whist changing a cylinder I still needed to use a bleeder as I got a 'long' pedal despite no air getting near the master cylinder.

Going to try my vac bleeder tomorrow

I wondered if I had flipped a seal in the MC, at 14 years old and 105000 if I have to replace the MC it is not the end of the world.

It has been a cheap vehicle to run all these years

According to JJ9 the seals in the MS can't flip so I'd take that as read. I have only once done what I thought was "flipped" the seal and it turned out the wrong fluid was used in the brake fluid reservoir on an old Rover SD1 and I think it softened the seals and one of them must have burst or jumped out of the groove on the pilot part (I expect it had to be pretty soft and squishy by then to do so)
