Good day,
Have a Hyundai 110d-9 in the shop for no working hydraulic functions. Unit has "low brake pressure" warning light illuminated. Do not have access to a Hyundai service manual at my work. Pilot/brake hyd pump was replaced at a different shop and customer states unit worked for a week and then started "screaming from engine bay" now no hydraulic functions, zero brake pressure build up, cannot release parking brake. Wondering if anyone has access that they can share to a service manual or hyd pump flow specs for unit.

Suspect hydraulic pump failure as no pressure measured anywhere in system.
