Bump again, lots of people PM'd me that they were going to
do this, but I've not heard nor seen it.

Anyone tried any conversion kits yet?

So I would think that to really do it right you would need to adjust the proportioning valve to accommodate for the extra breaking power in the rear. Perhaps turn down the total breaking force and/or direct more to the front so that the stock bias is maintained.

Scion xB has EBD (Electronic Brake Distribution), therefore there is so set brake distribution. What EBD does is to send more braking force to the front if there is more load in the front and more to the rear if there is more load in the rear.

The best solution in my opinion for braking performance is to get a bigger slotted rotor if possible with a wilwood caliper set. Drum brakes for a front wheel car is nice since most of the load is in the front unless you have something like a miata where it's darn light overall.

Wow ... 285mm rear ?!?!?!?
Damm you guys understand what that means, right???
You xB and xA guys have 255mm brakes in the front. So does some Echo guys and I am one of the unfortunate to have a 235mm in the front. That would make the car rear brakes clamp harder than the fronts.

And I apologize about not posting for awhile. That same deal with the Kingsmart the rear is too big compared to my front. So I ended up not doing the conversion. I don't have ABS in my Echo and I certainly don't
have electronic brake distribution. So it would make the rear brakes better than my front.
