Pajero Owners Club of South Africa

I recently fitted new Ferodo brake pad in the front and it work lekker, but for some reason I cant get the ABS to kick in. Last night I took her out for a spin after standing for about a week and at 100KM/h I punched the brakes and to my surprise the ABS didnt kick in. For me this is a very worrying factor as I drive in traffic that stop and starts alot. Is there someone that can tell me what to check for? Should I take her in to be plugged in with a dealer to see if all her "sockets" is in place?

Just some feedback on this issue, I asked around and after getting the right answers I felt like a tjop.
FYI, the ABS will only engage when your wheels start to lock. Well at least I also know.
