NCP90 Rear Drum to Disc swap

[Compeer]

Hey guys I own a NZ new 2007 trd yaris NCP90, It's a 1.5 vvti 1nzfe 5speed manual with full trd trim and only 133,000km so shes in great shape.. I have previously changed the speedo cluster to the Vitz RS jdm cluster (was not fun) and put 15x7" old school deep dish Roh wheels and some BF goodrich low pro tires to replace the 2000's 17" chrome gross wheels it had on it. I also spent a day scrapping the trd lightening sticker kit off it as it was crazy cracked, but may get it restored as it was a $750 trd option.








Ok so it has all the same or even better trd versions of parts like the vitz RS BAR the rear drums. The vitz rs has the rear disc brakes and thats where this crashed vitz RS comes in as the donor.

So the plan is full rear axle with everything attached so brake lines and ebrake cables.

So do I need the brake master cylinder as well guys? I cant find a different part number and people do other kits with out changing but thought Id ask and also document this a bit. Also anything else different for vitz rs? Does ecu have a different tune?

Shes low Km pretty rare car so this will only add value to her being the only actual Yaris with rear discs like the Vitz RS and allow me so many more brake upgrade options as far as pads and discs go.

Reading more on here i think I need the brake propertioning valve instead of the brake master cylinder? Tomorrow arvo i go to check out the car and tell them what i need them to pull off for my conversion kit which they gave me a flat price on, I just need to have the parts list ready.

Edit:
Checked out the donor car today and someone had nabbed a brake disc but also taken it apart and no bolts to be seen. So I may have to flag this. got 3 weeks before it gets scrapped so need to decide if i should just buy what they have and find new bolts.
