help , 94 530i RHD Manual 55k KM , i change the old power steering hose low pressure from pump & steering box , all the hose from reservoir because its leaking and the hoses is cracked and harden , because my car have a hydro-booster power brake assist from the power steering pump and the pedal is not worked sinking tothe floor and have ABS Light ON . After i replace the hose , the problem is still same , better feeling , still sinking to the floor and spongy, must be pumping few times before it harden.
1. what problem is this ? are my master cylinder bad ? brake bomb is bad ? or accumulator ? air in the brake line ?

you probably need a new master unit, inside there are 4 seals and a bakelite ring, the seals could be leaking, I posted here a disassembled brake master unit https://www.bimmerforums.com/forum/s...=bakelite+ring

Note that some parts of the system work at extremely high pressure so be very careful
OBD2 scanners do not work on the E34. It uses a system called ADS. But if you resolve the problem, you may not need a scanner at all
