    If you're thinking 15" wheels you might be okay but 16" would be fine. As you can see my 17" are heaps big enough.

    A quick calculation 2 x 170mm = 340mm = 13.5inches.

    I hate to make you feel bad Infotech, but that MA70 master cyclinder is listed as the same size as the RN85R, so your buy seems like a waste of money. I checked this in the Australian Truck and Auto Parts catalogue. It's too big for me to attach. I'll just be running my standard MC and Booster with the R32 front upgrade and MA70 rear conversion.

    Yeah, I saw your comment in the other thread. No biggie.

    I had already decided not to use it after the discussion about how the brake lines were set up on the RN85R.

    When I'm finished I'll gather all the leftovers and put them up for sale.

    Cheers,

    Not entirely true. If you use an appropriate bias control device, you can... but that just adds more complexity to the system, and one more part to fail, so its not really a nice option from an engineering perspective.

    I thought the RN85R had a bias control device at the rear. Or do you mean between front and rear?

    I mean a bias device, not a load proportioning valve which any ute worth its salt will have. Different items doing different jobs.

    i cant speak for an RN85, but as i mentioned way back in this thread the yn57 is balanced REALLY weirdly - hence i said id give you photos of my re-designed brake lines...quite frankly i cant see why the rn85 would be at all different in the braking setup -

    and the reason i said use the booster as well is so it matches well with the MC, its a hard call to say that a hilux booster will work well in combination with a supra MC, I know my ma61 booster is up to shit with the ma70 master...needs a fuckin lot of adjustment, which i dont know that i have...


    Plus, ive already said how good and smooth the brakeds were with the supra booster/ mc and the discs - why do anything different thats unknown territory?

    It's been one of those weekends were I seemed to be running around a lot doing stuff but nothing seems to have really got done.

    I had to put all the handbrake internals back into the rear end conversion. I remember pulling the rear discs and calipers at Pick'n'Payless took only a short time but putting the buGGers back on was a nightmare of skinned knuckles and hands with cramps taking hold.

    The clips/spring/discs that hold the mechanism to the backing plate gave me a heap of trouble. I did eventually get them on but it took about 3 hours for both sides. The springs kept jumping off, and then the adjuster mechanbism fell out so I had to start all over. After I finished I had to take everything off again as my adjustment was too tight and the wheels were locking up on a the handbrake shoes.

    All I need to do now is adjust the handbrake cable tension as the handbrake lever is a l o n g draw from the dash. That should be easy enough though.

    I did manage to clean up the MA70 booster and the master cylinder. This week I'll get a new gasket from Toyota and bolt it up. I believe installation requires the firewall to be enlarged a little so I'll use my Dremel kit for that.





    I'm waiting for the 3 way union to connect up the new lines for the brakes. I'll use some stainless to make everything connect up as I have some spare from the rears. Thanks to Blake (Robbos_Toyota) for all the info on how to do this. I'll write it up and take some photos as I go so stay tuned.

    Cheers,

    Peter
