hilux diff disc brakes

[jcmunga]

i know the MA70 / GZ20 backing plates, callipers and rotors are used. does anyone know if the MA61 uses the same setup?

MA61 brakes are different. They are 266mm in diameter, MA70 is 291mm.
The hilux bearing carrier is quite large, so you need a backing plate which will accomodate this.
I haven't had a good look at ma61 brakes so i don't know if the bearing carrier would fit inside.
Also, the MA61 is 4 stud, so rotors would require redrilling. Maybe have a look at MS123 crown. These brakes look similar to ma61, but with 5 stud.

Hope that helps.

Phil,
What if you wanted to keep the 4 stud pattern and also still wanted to run 14inch rims (with R comp's on them for competition/better gearing for example?) and to match up with a Corona/Hilux/Pug front upgrade?
MA61 rear discs on a Hilux axle 'should' be straightforward.
The backing plate seems to be the biggest issue here...

yeah,
i have the brake upgrade on the front converted to 5 stud, the only reason i was looking at the MA61 is there is one in the local wrecker and parts are cheeper than an import place for an MA70
did have a bit of a look and it seems that the barings for the hilux are bigger so im not sure if it will fit,

RA23, Yes the backing plate is the biggest issue here. If the ma61 backing plates will accomodate the hilux bearing carrier then it should fit with a custom caliper bracket and axles modified / made for 4 stud.
That said, some 14 inch wheels will fit over the ma70 brakes. I have seen a set of 14 inch mags on Gianttomato's crown and i've been told ford steelies fit as well.

Jcmunga, It's probably not worth the hassle trying to make something else fit if cost is the only issue. You're going to have to design and fabricate a new pair of caliper brackets to suit - as opposed to buying a set already made up (as sold in the classifieds section).
MA70 brakes can be had for around $230 through CVAP (forum sponser).
It's going to cost a small fortune just to make the diff fit in the car, plus there's added costs such as new brake lines, axle bearings and seals.
So whats a couple extra hundred bucks?
Just my 2 cents

thanks, i was thinking more about it today and thought should just go the MA70, whats a bit extra cash if ya know its going to work.
thanks again
