Hi, I have posted a couple of questions about the fact my warning buzzer wont switch off and assumed this was to do with the air pressure (even though it goes to 8bar and holds) I have been checking round the truck and checked the brake fluid and it seems very low/empty. I have recently had a new brake actuator fitted and wonder if they would have had to drain the fluid and maybe not filled it up enough or maybe there has been a leak? Would this cause the warning buzzer to stop on? and if so will topping up the fluid stop the buzzer?

regards

Do you have any warning lamps illuminated as well as
the buzzer sounding? The buzzer is wired through
most of the warning lamps. Low coolant will set off
the buzzer as well as low brake fluid. Have you
checked the wiring to the fluid reservoirs and pressure
switches on the air reservoirs? Could be faulty
pressure switch?
