Toyota said thenoise on my brake pedal is due to a faulty ABS pump. They said it would take around 5 hours to replace it with a second hand unit I got from Nippon Auto's. does anyone know if tha't correct the length of time involved? looking on you tube it says all you need to do is disconnect battery first then disconnect the electrical plug undo the pipe lines on the ABS unit and then unbolt from the body and replace the unit connecting the pipes back in and electrical connection. Anyone ever changed one?

Umm yep, i've changed 3 in my lifetime (Estima, Toyota Aygo & Smart Fortwo). all about an hour to do.

Looking at my 3Ltr Alphy i would say the exact same amount of time.

Unplug battery,

take of all old lines from replacement abs module,

take off all connectors (electrical) and bolts holding the old unit thats on the van off.

Take a 10mm/12mm spanner and undo all nuts from brake lines, then swap over quickly making sure to securly put the nuts on and make sure all pipes are in the right holes. (no-one wants a pipe in the wrong hole).

Then tighten all up and plugin eletrical connector. Then plugin your odb reader/software and run the pump to bleed the system. then bleed the brakes.

I do have Toyota Tech Stream I can send you to use, but you will need to have a laptop and a usb ODB reader todo this. If not then run the bleeding sequence a few times, take it around the block (carefully) slamming the brakes on to make the abs pump kick in. then re bleed. (i used to just fire the pump from the battery using some wire to the + and - from the battery to the pump about 5 seconds should do it no more though, *at your own risk as i've burned one out doing that before).
