ill see what i can do as i need to do an inspection on it...however initial eyeballing tells me that the axle/swing arm is a totaly different animal and the mounting points on the yaris are much further away from the axle as well as the "tie bar" between the 2 sides is about twice the size
that doesnt mean tho that any of the rest of the stuff isnt possibly the same honestly tho on the "hub" unit i would just walk into any orielys/ autozone(i hate autozone) and ask them to order one in if they dont have one on hand..that way you could 100% verify the mountings i will get what measurements i can tho im actualy useing alot of you and compeers data to try and put something together for the gen1 xb that will be coming home soon..as i KNOW discs in the rear would be really nice on it..but also "bigger"...so if i can help figure stuff out in advance i can then be ahead of the game for a swap on it since it indeed uses all yaris bits under it..i mean its a yaris with a toaster body LOL |

The Yaris SE's front rotors are 275mm O.D., which are what I have, the xB2's front rotors are also 275mm O.D. Yaris SE front rotors: Rotor Center Hole ID (mm) 55 Rotor Height (mm) 46 Rotor Hub OD (mm) 141 Rotor ID (mm) 130 Rotor Minimum Thickness (mm) 19 Rotor OD (mm) 275 Rotor Surface Thickness (mm) 22 xB2 front rotors: Rotor Center Hole ID (mm) 62 Rotor Height (mm) 46 Rotor Hub OD (mm) 155 Rotor ID (mm) 145 Rotor Minimum Thickness (mm) 22 Rotor OD (mm) 275 Rotor Surface Thickness (mm) 25 5X114.3 PCD here I come... |

i havnt had time to dig into the rear more, but i have gotten another look at the beam..its much more "heavy duty" than the delicate looking one in the yaris..i cant remotely fathom that the whole beam could swap...tho only measurements will tell the tail.....
as for the slight rotor differances compare the rotors on the xb to the camry..as the xb gen2 from my understanding is closer to a camry than a yaris |

There are so many Camry rotors, but here's the closest one: Height (MM) 49.5 Nominal Thickness (MM) 28 Outside Diameter (MM) 275 These won't work on the Yaris, because of the height difference and are even more thicker. All I need to know is if the xB2 wheel hub will work for the Yaris, and if the rear hub will bolt right on. |

all this for rims! good luck on the advnture lol. i vaguely remember that the xb2 rear hubs were a no go when i did research long long ago...and the rear brakes is a drum in disc setup, not the yaris's twisted caliper?

I think you need to look at your research again, the xB2 rear brakes are not disc/drum set up, they are just like the Yaris'. Looking at pics online, they look the same, the only difference is the caliper carriers are longer, because the xB2's rear rotors are 279mm vise the Yaris' are 259mm. And here are the dimensions for the xB2 and Yaris' rear rotors: xB2 rear rotor stats: Height (MM) 30.50 Nominal Thickness (MM) 10.00 Outside Diameter (MM) 279.00 Yaris' rear rotor stats: Height (MM) 30.4 Nominal Thickness (MM) 9 Outside Diameter (MM) 259 If everything works, all I need to do is mill down the xB2's rotor to 259mm. Here's a bonus pic, I tried the best I could with paint... The vertical and horizontal lines were center line references, and I lined them up, this is what I got. |

so i hit a yard today for some xb gen2 stuff and they had a yaris...sedan but whatever no good for me
i took off the rear hub then went and took the one off the xb, DIRECT SWAP, in fact i left the drum brake assy bolted up to the xb..so someones going to be SERIOUSLY confused so for the 5lug disc rear swap you could use entirely gen2 xb rear stuff, from the splash shield out its all a direct fit to the yaris ill see about posting some pic's...honestly i dont even think you will need to mill the rotors as theres a "slight" offset in the hub itself for me however im dead set on 2 things disc brakes that fit my wheels..14s on 4x100..and im slowly solving it |

That's funny you left the Yaris' hub on the 2nd GEN xB (I refer to them as xB2). First and foremost, thank you for helping me with my research. That's great news! You've mentioned before that the xB2's axle frame is more robust than the Yaris', that's also great! May or may not need to have to get a rear sway bar. When I said I'd mill the xB2 rotor, I mean I'd mill it from 279mm diameter down to 259mm diameter. And like I said before, I think this will still fit in the 14" wheels. The stock Yaris front rotors are 255mm, but the front calipers are bulkier, the rear calipers are much smaller. I'm moving forward with my "Alternative Rear Disc Conversion" as a cheap alternative. https://www.yarisworld.com/forums/sh...ad.php?t=63182 I might even produce some mounting plates if others are interested on doing the swap, for purchase of course. If you have the time, would you please try to remove the front xB2 steering knuckle, and see if you could measure the outside diameter of the front wheel hub in the bearing, or measure the inside diameter of the bearing? I suspect that will also fit in the Yaris' front bearing, which is 40mm internal diameter. |

it litteraly started snowing while i was out at the wrecker yesterday, and my figures hurt like hell, after my last stop at another wrecker, it started really comming down, i attempted to shortcut and back road my way home as the freeway had multiple wrecks n such......in the end it took me 4.5 hours to go 18 miles.....
were kinda snowed in so ill pull pics from my phone of stuff but im not settin foot outside for a few days lol the real catch on my disc swap is not just the 14s but trying to stay "close" in size on the rotors to whats on there stock, anything bigger up front isnt likely to clear as the wheels are light but a bit pudgy on the inside |

The weather this Saturday will also suck where I am. But I still plan to go forth with my rear disc conversion. There's a bit of experimentation whether I should use the Corolla calipers or the Yaris calipers. Check the other thread for that info. If anything, I'll at least weld the brake hose brackets on Saturday and finish installing everything on Sunday, when the weather is a bit nicer anyway. Well, I have to finish on Sunday, because I don't have another car to get to work on Monday. Today we're expected temps in the high of 80*F!!! I wished that were the case for Saturday. What I've been trying to tell you is that the rear disc conversion WILL still fit in your 14" wheels. Your current front rotors sizes are 255mm (which you don't have plans on replacing), the rear disc are only slightly bigger, 259mm. The rear calipers are less bulky than the front rotors, so they will clear the 14" wheels. So you don't need to do any other modification, other than you'd probably need a proportioning valve installed if you don't have ABS. Yes, the xB2 does have 279mm rear rotors, but if you use the Yaris rear calipers, they will bolt on the xB2's axle frame, difference is that the caliper carrier is shorter by 10mm I believe. So you can still use the xB2's rear axle frame for the rear disc conversion if you're saying that they will fit. Here's an overlay of the Yaris rear caliper on top of the xB2 rear caliper. As you can see the mounting holes for the xB2's carrier is a bit farther out to accommodate for the 279mm rotors. Now back to the original topic, the 5 lug conversion is not for you if you insist on staying with your 14" wheels. Even though I think that 15" wheels can still accommodate the 279mm diameter rotors in the rear, I'll still mill them down to 259mm. |

https://www.rockauto.com/en/moreinfo...t=1896&jsn=866 It's also where I bought the parking brake cables. https://www.rockauto.com/en/moreinfo...t=1696&jsn=969 https://www.rockauto.com/en/moreinfo...t=1696&jsn=970 I'll do you a favor since you did me one, once I install the rear disc conversion, I'll see if I can find a 14" wheel, and see if it'd fit. And if I end up using the Corolla calipers with my disc conversion, I'll be selling the Yaris calipers I bought, I might even make the adaptor plates to go with them. That's only if I end up using the Corolla calipers. |
