Bentley Brakes and long start up

[davidat]

Hi all, can anybody help please? I have a Continental R 1994 and the vehicle checks at start up seem to take forever, some 3 minutes. I believe it should be 2 (extremely frustrating). Often the brake pressure warning flashes and so I check the hydraulic level in the reservoirs and they seem to fine so I wait and then it starts. Today it took 5 mins!!!
Any ideas, do you think it's an electrical problem, hydraulic, brake line leak???
Also the acc position on the ignition switch doesn't seem to work.
Any suggestions, comments or advice gratefully received.
Best regards......

Thanks to andy and escort1983 for their advice and suggestions, I'm a bit new to Bentleys. I know they have 2 braking systems for front and rear but does each system have its own acc and pump? Thanks
