front backing plate and/or spindle (1 Viewer)

[lc69hunter]

I am doing a front disc brake conversion.

Taking it apart is fairly straightforward, except:

On the driver's side, I took off the wire and removed the 8 spindle bolts, and the backing plate wouldn't come off. I pounded and pried, and finally it came off with the spindle. I tapped out the spindle with a piece of wood, and put it back on with a couple of bolts.

The passenger side will NOT come off, either with the spindle or without. I have pounded and pried, and cursed more than a little bit.

Any ideas? The only thing I can think of is a bigger BFH

Free all and persuasion is your only friend. Try to not damage the spindle if it is really stuck you might use a block of wood and let the trucks weight work for you. Block up the spindle and then let the truck down to free it. Worth a try if your stuck.

You need to soak the part in a product like Evapo-Rust. It will break down the rust keeping the two parts frozen together. It could work in as little as an hour or two but more than likely it will take over night or even a couple of days.

are you doing a knuckles out disc conversion? and this is on the drum axle?
leave the spindle on and just remove the knuckle and spindle assembly as a unit.

The piece of wood and veh weight itself didn't work, but it may have helped. It was the bigger BFH that finally did it.

I have a little grinding to do (<1/16 inch), as the hubs won't quite seat into the rotors. JT Outfitters warned in the installation sheet that that may be necessary, because of the differences in trucks. That's OK because I had to order new spindle gaskets anyway and they won't be in for a few days.

Congrats, sounds like your on your way.

I understand. I have a big heavy rawhide mallet for just those days

Check into not using the disc brake backing plates, brakes will cool better, and rocks won't get stuck between rotors and backing plates. When Downey was in business we use to make special hoses that let you remove the backing plates, and I believe Marks Off Road made spacer plates that took up/replaced the thickness of the backing plates.
