    7300 and 7395 are rear axe modulator fault codes, usually bad modulator ore low primary air pressure

    to be sure inspect rear axe modulator air supply (from primary tank), and cheack rear brake chambers (combined with park brake)

    about 9-10 BAR

    It is not all, check air system for oil in air and check air driyer. This oil and moisture damage modulators.

    You need Wabco diagnostic tool ore Mercedes SD to check modulator, but IMO is is bad and must be replaced with new.

    Is it Germany made truck?
