10"drums

Hi all, Anton has been trying to fit some 10"drums (thanks Pete) to the dart to replace the 9" ones. Here is the problem. as you will see the 2 backplates below have a different spacing for the studs and the spindle size is different. Is there a different backplate I can get that will work? They are small PCD by the way

'Fraid not, you have to change the spindles as well, believe the bearings are a different size also. As a rule of thumb all Mopar front brakes have their own specific spindle, 9", 10", four pot disc, single pot, disc all different.

Right, thanks Blue... Damn thought this might be a relatively simple swap... So I would Are spindles easy to come by? Bearings need renewing anyway so that's a positive...

You might struggle to find them over here but you will get them on US eBay, that's what I had to do last time I needed some.

Just a thought... SSBC seem to do a kit that will bolt on to stock 9"drum spindles. I was thinking if I go down this route I'd like to stick with a manual brake master cylinder. Does this work? Or is it going to be scary?

That is by far the best plan you have had to date, Dorian - manual discs are fine if you get the Master Cylinder sizing correct.

Just got off the phone with Wayne... What a character, and a really nice guy.
hes supply's re produced 73-76 E body disc brakes with a few tweaks. Basically means I don't have to change the UCA's and I can use a mopar manual master cylinder and keep a smal PCD... It's going to add a few pounds in weight but should be pretty reasonable in terms of cost and hassle. He even inferred that the value of the customs declaration would be balanced well in my favour. He has some great videos on his website which explain everything. Thanks again Miles
If any one thinks this is not the right way to go I'd appreciate your thoughts?

any way you can get disks on the front is good

just depends how much you want to spend and how much you are up for doing your self to get them to work

this looks like a No-fight-easy-install medium expense route.

if you keep your master cylinder
pull the residual pressure valve out of the front brake outlet with a self tapping screw (most likely to be the back outlet)

and replace the rear wheel cylinders with those of a 94 dodge Dakota
these are the narrowest OEM rear wheel cylinders hence help heaps with brake balance once you get the disks on the front

Dr Diff does some well useful stuff as well

http://www.doctordiff.com/brakes/

including sleeves and bushes to get various mis matched parts to work together safely

i.e inserts to allow the use of big ball joint spindles on small ball joint taper

also does brand new disk brake spindles for $185 a pair if you suddenly get the urge to build up your own kit

if you want dropped spindles for disk brakes to lower the car but keep full suspension travel

these aussies have a great rep
