You need to take the following photos out of a previous reply...
They are wrong, confused me and caused someone else to wreck a backing plate

So to others doing this, the hole alignment is wrong.

That photo is WRONG. My apologies. The photo a bit further down shows the correct location.

You say it's wrong but you don't say why and you don't offer an alternative

Its just those two photos that are wrong.
Your photos/diagrams further down with the purple text are good.

Correct, that one is good.

Correct, that one is good.

You'll notice that the preceding sentence to those photos clearly says "The next two photos are NOT directions but questions aimed at clearing up the next stage of the process." I was asking "Is this correct?" It obviously wasn't and the photo further on shows the correct positioning of the cut.

My setup... RN25 diff modified for RA28 mounts with MA70 brakes.
The dust covers on the backing plates have been removed.
(FYI, the factory RA28 handbrake cables work)

Yeah i know, after a while i did work that out.
Unfortunately bigmatt didnt and drilled the holes in his backing plate in the wrong spots and ground off the wrong side of that plate

I was just saying it would be a good idea to now remove those photos to stop other people who dont read the text above from making the same mistake
Sorry if it sounded like i was blaming you Peter... i wasnt.

[infotechplus]

No worries. I've modified that post to make it more obvious.

You're setup looks very good. You really notice the braking improvement!

Cheers,

Peter

Thanks, i hope so.
Ive got EBC Blackstuff pads on the way for it was well.

Some heads-up for anyone doing/contemplating this conversion ...

I was at Pick'n'Payless Blacktown this morning (Wed 10/10/2007) having a wander, and there is an MA70 Supra there with the rear brake package still on it. Looked pretty clean too!

The diff was gone so it should be a quick pull to grab them.

Actually now that I think of it, I should have checked to see if the master cylinder and booster were still on it. I'd hazard a guess and say YES as the car probably hasn't been there long given it hasn't been totally picked over.

Peter

Any liteace vans...............

Youngy, you dont need the lightace stud anymore. You can get away with using;

1x ma70 stud for the thickest section and
3x the standard hilux ones...

I have given up on trying to do my own drums as its just to much crap so im going to get them done next week by someone. Unless someone has some spare time and likes beer and can get down to northern beaches

I think Youngy is referring to the handbrake cables not the studs as we have done away with that myth some time ago.

And BTW the Supra no longer has its rear brake setup out at PnP.

Unfortunately the brake master cylinder and booster were already gone.

Yeah I was referring to the hand brakes cables. I might have to trek out to those wreckers you got one of your cables from Peter!

[infotechplus]

When putting the handbrake assembly back together on the rear, make sure you put the colour-coded springs back in their correct positions. First time I did this I didn't realise they were coded until I read a section of the online TSRM.

So here's the diagram for the DRIVERS SIDE. Make sure you reverse the codes for the PASSENGER SIDE.



They may give you a bit of trouble but this is the correct way of doing it for tension on the handbrake shoes against the backing plate.

PS. I rang Toyota to enquire about new backing plates (as these are the hardest to remove from the MA70 rear end) and was told they had no stock in Australia. A quick call by the rep to Japan revealed they had no stock there either.

After an hour he rang back to say Toyota Japan could supply new backing plates in 10 working days but they would have to tool up to manufacture them.

The cost: $320Aus each side.

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