    Volvo L120F Warning Brake Sys Failure

    No loss in hydraulic oil/ no gain in transmission. I'm assuming your asking because of possible leak by into either system.

    Volvo L120F Warning Brake Sys Failure

    FWF, Appreciate the help big time! Just FYI I have the parts manual for this thing, so you don't have to waste time looking for them. On a side note, its takes about 2 weeks, maybe more, to get parts out to where I'm at. So after this you probably wont be hearing from me until then. I will keep...

    Volvo L120F Warning Brake Sys Failure

    FWF, I've got good news I think. I mean we are making progress. But with that line disconnected and capped from the T-Fitting my pressure shot up to 2240PSI, but also with that line capped the accumulator pressure seems to leak down a lot faster. So I think I'm leaning back to it being that...

    Volvo L120F Warning Brake Sys Failure

    FWF, My results are as follows, 2) pressure stops at 1807 3-4) each time I pressed the brake pressure would drop down to around 1620-1660 psi before building back up my average was 1636 psi 5) with the bucket curled back there was no psi change in accumulator pressure. After completing this I...

    Volvo L120F Warning Brake Sys Failure

    FWF, Thanks for the input. I will let you know what my results are. Also thanks for pointing out that check valve, it just looked like a regular hydraulic T-fitting whenever I was replacing the accumulators, didn't think anything of it.

    Volvo L120F Warning Brake Sys Failure

    Paul, Accumulators are brand new and pressure sensor is brand new just installed yesterday before I joined this forum. That's what we originally thought as well after diagnosing that it had to be bad accumulators, but still a no go. That's why we are so boggled by this warning message...

    Additionally, accumulator pressure gradually drops by 4 psi every 15-20 seconds with engine off.

    Volvo L120F Warning Brake Sys Failure

    Correction, my accumulator pressure is now at 2050 psi with engine running. I am providing readings from SE5218 being sent to operators display in service mode. That's how I provided the numbers in this post originally. I do not have a pressure gauge compatible with the system. We are quite...

    Volvo L120F Warning Brake Sys Failure

    Paul, Fan speed I think is sitting around 440 RPMs, does not over heat, and no attachment just a plain bucket attachment(non-clamshell). Thanks for the quick response!!

    Volvo L120F Warning Brake Sys Failure

    I've got a 2009 Volvo L120F Loader that is throwing a Warning Brake System Failure message. Accumulators (new), Sensor SE5218, Solenoid MA5502 have all been swapped from a working loader we have in shop and it still hasn't solved the issue. We tested and measure the wiring from V-ECU to the...
