Pumping the brake pedal should depressurise the hydraulics, I don't know of any other way. If you got the accumulator off, there could not have been any hydraulic pressure in the system.
What is the actual problem? Is it brakes locked on?
Thanks for replying.the front brakes get very hot that hot as one as the Paint bubbling have changed the calipers pads and discs and the Flexi pipe .I changed the accumulator about 9 months ago and think it started then I now won't to bleed the system to see if that's helps but I can't depessurerise the brakes by pumping the pedal.the pedal just goes rock hard I'm hoping someone can help

My personal guess would be, starting with the brake that gets hot, connect a pipe to the bleed nipple on the caliper, loosen it then you should be able to pump the brake pedal.. loosen the others if necessary

Has the brake fluid ever been changed? If not I would start by doing a complete fluid change bleeding according to the procedure in RAVE, Brake fluid is hygroscopic and moisture in the fluid can result in mal functioning brakes.

If the pedal goes rock hard that normally means that the pressure has gone.

Are you sure? It's been a while so i could be wrong but I'm sure mine went very soft
Vacuum assisted brakes would go hard

Pretty sure there was long travel and a soft pedal on mine with no pump,
Rave says the pedal should go soft and it's always gone soft before
That's what I am trying to do depessurerise the system then rebleed it

As per my other post, i think if you let pressure out of the calipers, you might be able to pump the pedal more and get to the real problem

Undo all the caliper bleed nipples and see what comes out. I suspect there may be a problem with the modulator often caused by old brake fluid.
Will do and get back to you all thanks for the help

Slide pins causing caliper to bind on?

Might cause overheating brakes but not the problem the OP has with not being able to depressurise the brakes.

More likely to cause uneven pad wear
