Guys, really need your help on this one:

I'm 99% complete on my rebuild where I've replaced almost everything

My front brakes are still binding despite rebuilding/replacing everything:

New wheel bearings
Replaced everything inside servo
New master cylinder (tandem type)
New brake pipes
Calipers refurbished by BiggRed (I finally gave up and sent them off after refurbing them myself).
New pads

Brakes are binding to the point where excessive force is needed to turn the discs. When pads are removed discs turn fine. I'm certain it isn't the calipers as I sent them away to be sorted- could anything else cause this?

Love to hear your thoughts!

ok heres my thoughts. what type of pads are you using. standard or some performance type ones?

From what your saying I think that the new pads are to thick and so they are hitting the new disks and binding. The same happened to me when I put new rotors and aftermarket pads on my ford falcon. SO im assuming thats the pads and disks are new. maybe go to ur local mini parts place and get them to measure the thickness of the pads. And compare to yours and other types/brands. I think you'd just need slightly thinner ones

I didn't think about this but yes, they are supposed to be performance pads. I've still got the old pads with plenty of meat on them so I'll give them a shot first. Thanks

thats ok.
see how ya go. What I did with mine then was find a level surface and some sand paper. then grabbed my pads and sanded a bit of the pad material off untill they fitted better. I know its dodgy but it worked lol.

My new pads were a tight fit with new discs on.

We sanded off the layer of paint on the pad (back and sides), and that was just enough to give it enough clearance.

Putting old pads in didn't make much difference. I'm gonna check the pipes in case there's a kink somewhere restricting the fluid from moving back as easily.

Crack the bleed nipple open.
Push the pistons back in as far as they will go.
If they still won't fit properly, I'd file/sand/grind the pads down. Wouldn't do the first ones I'd had to do this to.
Wear a mask, watch the dust.
