disc brake conversion Question

[Brandon]

Hey mangs. As some of you may know I have a 99 crown vic that I am wanting to keep the disc brake setup for the rear. I have learned that these have the bigger brakes as well. I was wanting to know what all I need to keep from this car. I am planning on doing this to my tudour I just didnt know of what all I may need.

And second this one is off topic but will the seats work in my 91? the both cars are manual seats.

Seats will work.

For the rear discs, you need the backing plates, the calipers, hoses, rotors, parking brake cables. You will need to remove your axles to swap the backing plates, use your old axles in the reassembly. You cannot install the 99 rear in without modifications of (noone knows because noone has done it.)

For the big brakes, you need, the upper control arms, the spindles, the hub assembly, the rotors, the calipers, the caliper mounting brackets, the brake hoses. I think that's all, I could be wrong so check around, there's a write up of what all you need around here somewhere.

You want 92-94 upper arms. You can make the 99 ones work, but its more work than using the 92-94 arms. It involves taking the pivot shaft out of your stock arms (not police arms, they need to be civi arms), removing the bushings from the 99 arms, installing the shafts into the 99 arms, then putting the bushings in again. The 92-94 arms already have the shaft, and you can just bolt them in. I'd replace the bushings, but you don't have to take apart a set of box arms to have everything you need.

I dont know how different the 98+ rear brakes may be, so you're gonna have to wing it to an extent there. I(ts probably basically the same as the 92-97 stuff tho. Assuming it is, you need the stuff John mentioned above.

Okay super! Thanks alot mang.

Sounds like the front brake set up on the 99 is going to be a pita. Maybe I hold off for the 92-94 model.

upper arms I hope you mean. The 92-94 brakes are the same size as what you have. Just snag the spindle assembly out of the 99, and grab the upper arms out of an early aero. A little mixo-matcho magic with the lower ball joint and it all falls together.

I could be crazy but I am sure you could use new bushings by now and it wouldnt hurt just using the 99 stuff then if you had to change upper shaft of the control arm. You have everything you need already...just need bushings.
