Hi, I have looked through the archives to see what information is about, on how I can check my ABS brake system. Basically, the tester at my local NCT test centre , in Ireland, has failed my P38 initially on the ABS not working, and then secondly on the handbrake not having sufficient brake force.
So, the image is of the brake test arrangement as used by my local, and only test centre in Dublin [north], which they insist has been updated to be able to test permanent for-wheel drives.
On my last test, a couple of days ago my P38 failed the ABS test until, after 40 minutes of heated discussions, got the tester to drive the vehicle on the road outside, after which he came back, and with very bad grace, accepted that the ABS "seemed" to be working OK. But then, like a Monty Python sketch, he told me that the vehicle still failed the test because the handbrake had insufficient force - "so there" !
I can accept, to some degree, that the handbrake may not be as good as perhaps it could, maybe it needs tightening up at the adjuster screw on the drum, but the brake is able to hold the vehicle, on the second "click" of the brake lever, on a slight hill even when putting light pressure on the throttle to increase the engine revs. The vehicle doesn't move forward, but, again, I accept that this is not a 100% test of the efficiency of the handbrake. I will try to adjust it tighter this weekend.
So my two main questions are firstly, - how can I physically test the ABS system, and how would I know if the ABS pump is not putting as much pressure out as it should ? Is this possible, that the pump pressure is being reduced by age and use, or does the pump either work or not work, thereby needing replacement.
The second question is - what is the best way to test the handbrake, allowing for the fact that I am doing this outside my house and not in a garage ?
Hopefully, the forum may have some updated advice on this issue.
