98 ford expedition rotors

[sprancey]

i am currently in the process of replaceing the brakes rotors and calipers on my roommates car and ran into a problem,the rotors are pretty much fused to the hubs with rust.I tried beating on them with a hammer but nothing yet.does any body have any ideas that would help me out?

 

[sprancey]

does anybody have any suggestions

Sucks noone got back to you, this happened to me on my expedition and just need to keep on it and make sure you have some pressure as well as you are hitting it. It will eventually come off!

Some penetrating oil and a bigger hammer. My 350 has the same design and you pretty much have to destroy the rotor sometimes to get it off.

I clean and coat the hub with anti-seize before putting the new rotors on. Seems to work well so far.

Iv'e had to cut them into two or three pieces with an angle grinder a few times to get them off.

Just beat on them between the studs and usually they will pop off.

Gotta hit 'em like you mean it though...

This is a very common problem on the explorer/expidition, here are the methods that have worked best for me:

1) Use a chisel and put a couple of good lines in the rotor. Heat these up with a torch until they are Red Hot. Throw a large cup of water onto the red hot surface. This will generally shock the rotor and crack it, sometimes you can help it along with a nice blow from a hammer after the water.

2) Grind some reliefs in the rotor right where it meets the hub. Use a Big hammer and whack it off the hub. This method takes a little longer, but always seems to work.

These things can be a friggan nightmare!!

Well, I have been working the the brake testing industry for 15 years now and you are pretty much screwed no matter how much beating you do. The hub will go bad before it comes off. The 97-98 Expedition and 150 Ford didn't use any anti-seize, and it pretty much welds itself together. We had one that was a year and a half old(Detroit winter) and no go. Even had torches on it glowing red and a sledge hammer, rotor broke but not off the hub.

Your best bet is to pull the 4 bolts for the hub and replace the hub with the rotor. another option is to find a brake shop that will turn the rotors on vehicle with a pro-cut or hunter on vehicle brake lathe. if you go with the hubs just apply a liberal amount of anti-seize.

thanks for the help huys i finally got them off i ran a 4 inch bolt thru the caliper mount braket with a nut on each side and just cranked on them evenly and they popped right off

Sorry I couldnt respond quicker, this account just got activated. My Expedition did the same thing. After squirting penetrating oil where the rotor meets the hub on the back side of the rotor, I just used a 3 jaw puller to get it nice and tight, then taking my 4lb sledge, I smacked the braking surface for all I was worth. The first rotor broke a few pieces off, but gave up the ghost after I meant business and came off "whole". The second rotor didnt stand a chance, it was badly worn and after the second swing, the rotor split into two pieces, then just needed the center section knocked off.
