Hi all.
Back again.
At Xmas last year I had the ABS brake booster motor in my UZJ100 fail while away on holiday.
I posted about that here:
ABS warning light and audible alarm, brake failure soon after....possible easy fix to get you going
In short, I cleaned out the motor, reinstalled it, and it worked again, to get me through my holiday, back home, and for several months later, when again it failed.
I then replaced the rotor, commutator and bearings as one unit, along with a set of brushes, all purchased aftermarket from the UK, and, despite being significantly noisier, seemed to fix the issue.
Despite much headache and delays...
However, last week, I was driving, and the ABS motor came on during braking, and stayed on.
Not wanting to burn anything out, I quickly pulled over, and turned off the ignition.
When I restarted it, it again immediately came on, and stayed on.
However, after a few times, of turning on and off the ignition, it did start to turn off.
However, the brakes seemed to not feel as good as before, and soon after, the ABS warning light and audible alarm came on, and I'd lost brakes.
The motor started to come on for two seconds, then off for 8 seconds, and kept doing that.
After leaving it for a few days, it now does the turn on every 8 seconds, stays on for 2 seconds, then is off again for the next 8 seconds.
Any suggestions?
I assume it is either the brake booster motor again, or the accumulator can, but I cannot be entirely sure.
At a guess I would assume the motor, as accumulator failures seem rare, and of course using aftermarket parts to rebuilt the motor are highly suspect...but then, I would assume that rebuilding the motor, it would either work, or not work.
So I suspect that perhaps its detecting its not building up pressure in the accumulator, so it stops, and then restarts it?
I did a sound recording with my phone, not realising that *.m4a audio files are not allowed to be uploaded here.
Any help greatly appreciated.
