  • Over the last month the pulsing pedal had gotten worse. It started some weeks after last pad change.Bit the bullet and bought another set of rotors and pads. Majority of the issue may have been a seized slide LHR but not sure. Front LH was a little sticky too. All new stuff in and smooth as the proverbial bum

    • NOT today but on the 31/10/2021 sold my 2012 4x2 PB Challenger with 92403km on the clock. It was the first new car I have had bought and we loved it but decided to replace it with a smaller city SUV which is more suitable for our use. I still have my MN Triton so will remain here in the background.

      • During a recent trip to the northern Flinders, my PB's RH low beam headlight failed.
        LH low beam was still working ok, implying that it wasn't the low beam relay or controls that were at fault.
        There had been a flicker when I first turned the headlight on . . . then nothing.

        Thinking/hoping it was just a bulb or a fuse that had failed, but that wasn't to be.
        Turns out there's a broken wire (positive) that's down to ground (about 0.5ohms) on the load side of the break. Had it been just an earth fault without a break it would be fairly easy to nail down the location. Might try passing some current to ground through the wire and detect where the wire's field is present/absent using a magnet on a string, or a compass.
        If I disturb the earth fault to use a clamp meter then there may be no way of getting current to flow.

        It would be relatively easy to run a new wire from the fuse box to the headlight, but leaving a fault somewhere in the wiring/loom doesn't sit well with me.

        • Great success here. Wiring fault was very close to the car's fuse box. Tracked it all the way using my magnet dangling on a string and a pulse of current through the wire.

          Installers of wiring for bullbar appear to have stuffed up a joint, which had broken and shorted to ground (or vice versa perhaps).
          Weakened wiring from their joint must have blown before any protective fuse.

          Results of various tests all make sense now.

            Good result, it'd bug me as well knowing something was wrong in the loom (I once had to redo the ignition wiring of my Landrover on the side of the highway due to an earthing live wire).

            What however is the magnet on a string trick of which you speak?

              Quite simple really:

              - Attach a small super magnet to a lightweight thread (cotton, string etc). My magnet was 10mm x 6mm x 3mm and thread was about 150mm long.
              - Dangle the magnet in close proximity to the wire under test (try beforehand with the magnet and current that you are using to see how sensitive your setup is)
              - Allow the magnet to settle and stop swinging, then repeatedly pulse some current through the wire. I was charging then shorting a large electrolytic capacitor as my source of current pulse.
              - Current in the wire produces a magnetic field around the wire which interacts with the field of the magnet.
              - The dangling magnet thus produces a visible kick in response to the flow of current in the wire.

              The tech heads amongst us would know that the interaction between current in the wire, the magnetic field and the force between them can be predicted from 'Fleming's Right Hand Rule'. A mutually orthogonal set of the quantities (Force, Magnetic Field, Current) tells us what will happen when any two of them interact and results in the third.

              • Brilliant Kingbrown. Never ceases to amaze me what I can learn in this forum.

                • Major service. I see the PS pump is wet but not leaking and appears to come from the front seal, anyone had to deal with that?

                    I haven't had to deal with a leaking power steering pump but concur with your assessment of a shaft seal on the way out. Unless the service person dribbled some oil on the pump. You could clean it up and then monitor to see if it gets any worse I guess.

                    Provided the shaft itself isn't scored/damaged, there's an overhaul seal kit available for less than $50, 4451A042

                      Well if the servicing person spilt oil in topping it up I'll kick his bum...( ME!).. No I noticed about half the pump was wet last service but this one it is completely wet. It is down a fraction but not enough to worry about yet. I'll monitor it and get a kit and have it sitting here at the ready.
