Hi, we had issues recently with the rear car height and brakes and we changed the brake pumps. The brakes and car height became normal for a while, but now suddenly the rear brakes won't work normally at all and the car's rear won't lift to its normal height either. The 'pressure low' warning lights also continuously display.

What should we possibly look into now? New member here so any help will be kindly appreciated! much thanks.

Hope your brake pumps comes from a serious source. Where did you get them ?
Could be front brake accumulator with broken membrane both.
If you front sphere are old, this is the simplest and obligatory to start with

Also flush and bleed LHM

Could be brake accumulator vavle body, check second line, this is connected directly to the front sphere.

Could be also Height control valve, check here first items

This is too start
Thanks for your input! We bled the LHM and the brake lights have gone off and the car's rear height is at its normal too. The brakes were fine but when we press the pedal, the warming comes on for less than a second before going off again. We believe it might be accumulator with broken membrane?
