How to: Supra MA70 rear discs to Hilux

[Esteban]

You must spread some Reputation around before giving it to infotechplus again.

Indeed!!!!

In case anyone else is following this process thanks to Peter and GT this might help. The rebuild kit for the rear calipers from the MA70 has this Toyota part number:

0447914110 - about 77 dollars

I tried to get a rebuild kit through PBR but was told they have stopped making one!

Toyota wanted 5 weeks to get the rebuild kit! I got one through IBS - part number is K2041S. 65 dollars per side.

Hi Guys,

After talking some more to Peter about the handbrake cables and having no luck sourcing some liteace ones I just spoke to these guys about getting some made:

http://www.conwire.com.au/

Obviously things were a bit hazy over the phone but at this stage the cables look like costing 40-50 dollars each, built from new components.

I'll let you guys know how I go

Im using standard celica cables to suit my diff and brake upgrade...

Any reason why that shouldnt be done?

Any reason why you guys cant do that either?

Only comes down to length and the little attachment nodule at the caliper end to match the Supra setup.

Hi Guys,

Went to Conwire today and picked up my new cables. Got them made up from some spare hilux cables I had with obviously the rear end of the cable changed to suit the supra set-up.

All up $110 and they called me to say they were ready last Friday (same day I dropped them off). So pretty impressive I think.

Obviously the truth will be in the fitting.................

[infotechplus]

Youngy,

Well done. +rep to you for this.

So you left the length the same and just changed the nodule attachment at the end?

Before you put them in, can you measure them from end to end and post the length here for future reference.

Cheers,

Peter

I got my rears in finally, they look the goods. I had to trim away some of the backing plate and then was all good and dandy

I used the standard Celica cables to get it all in and works a dream!

Just gotta adjust the drum to the right spot, get some rubber break line and im all done on breaks

Cheers,
Jase

smokey

is using the standard celica cables pretty straight forward or is there a bit more ot it?

[Smokey228]

Just straight swap. Nothing more to it... Very simple...

P.S. I had to get the brake shop to do my drums, i couldnt get it. But ill post a pic of them finished off!

THIS IS VERY IMPORTANT IF YOU WANT IT TO BE EASY! LOL
Assemble the drums to the backing plate before you have the backing plate put on and all the bearings and stuff pressed to the axle!

Cheers,

i got a bit bored at work today.. so bunged a proggie in the plasma cutter to test out some caliper brackets.
and theyre a perfect dimension match to the one i got from Infotechplus. cheers mate.

heres some pix.

[Youngy]

Wow, the brackets are going to be easier to come by than MA70 parts soon!

Anyway all a few more things from my experience. When I got my MA70 parts I had to rely on some others to get the parts. Anyway whoever got the handbrake set-up off the car did so with a bit too much zest - hence I had to get some things from Toyota

the black spring - 9050720016
cup shoe hold (near shoe, updated with locking tab) - 4744940010
show hold pin (dog leg bend in it) - 4744750010
the blue spring - 9050116053
the white spring - 9050114049
cup shoe hold (near pin end) - 4744930030

The green spring and straight hold down pin (go figure) are not available from Toyota Australia but could probably be sourced from any other Toyota outlet in the world.

green spring - 9050716011
straight pin (primary) - 4744714020

I am using two black springs which will make the handle pull a little harder, not much in it really.

Peter - I'll get the handbrake cable inner and outer measurements tomorrow

[P100_Ute]

excellent job with the part numbers man.. will be a great help to everyone doing this conversion.

i got asked about handbrake also..
and i went to the Hot Rod scene for the answer and found this on Agony's 32 Ford.

put the handbrake on the diff flange. thats using a Go Kart brake caliper on a disc that had been laser cut.

[Youngy]

Hi Guys,

The Hilux handbrake cables have different length outers as one (drivers side) is held with a spring clip on the front side of a cross chassis beam and the other (passenger side) is held on the backside of the same beam.

Hence

drivers side - 1206mm outer and 1956mm inner
passenger side - 1115mm outer and 1957mm inner

[Youngy]

Another small up date from my experience with this conversion.

I have found that for what ever reason on my car one side had 41mm serration bolts and the other side had 35mm ones. As you know you need six 41mm serration bolts and two from the MA70 to do this conversion. I have been to my local wrecking yard a few times without success so I thought I would try Toyota since it looked like the Hilux probably had 41mm bolts anyway.

Got two serration bolts for $6.30 - and they are 35mm

DO NOT GET PART NUMBER 9011410002
