press on brake pedal and spongy u can get some pressure at the bottom of the pedal. tried bleeding all the brakes also changed the master cylinder and bled brakes again but still no joy. would be thankful for a solution if anyone else has had or having the same problem. any advise or help would be gratefully appreciated

how does pedal feel with engine off, if its hard then fault is in vacuum /servo system,if still spongy then you have hydraulic fault,[did they just go spongy or have you worked on brake system?],calliper slide could be siezed and causing fault,have you fully bled system,have you checked brake hoses for "balooning " when under pressure,try clamping brake hoses in order to determine which brake assy is at fault,check rear shoes makesure linings are secure to shoes [can become detatched due to rust,] check for excess play in wheel bearings.also make sure pedal fixing not broken/insecure in pedalbox. if you have changed any of the callipers-is the bleed screw at the top [had this fault once after system worked on by amature mechanic who fitted callipers to wrong sides!]

the only thing left that it can be is the servo, i have been a mechanic for the last 8 years and you have done everything in the right order so the only thing left is the servo but before going out and replacing that just make sure that none of the vac pipes are losing pressure through them e.g cracked or split in them
