People yo from Kingsbury in warwickshire

I need some help please?

I have the usual ABS and Traction warnings on but have changed everything, and i mean everything...wheel sensors, pump, accumulator, disks, pads and even the fuse box. The lights went off after changing the pump for about 2 weeks then came on again. The computer shows no faults...what the F*** am i missing?

What else can there be or has my replacement pump (i was advised it was good and indeed worked ok when installed) also bust.
