while attempting to do a firly routine front pad&disc replacement i came acros a little problem: the discs are stuck, i mean REALY stuck, likie someone welded them to the hub (and no i didn't forget to take out the two retaining screws). there is a fair amount of rust on em but the one hub looks a little smashed up like someone beat on it trying to get the berings back in at some point.

I've been beeting on the d@mned things all afternoon and soaking them with lots of liquid rench. i need some ideas on how to get these things off because i have run out.

any thoughts welcome

thanks

 

I had the exact same problem two years ago when I did a brake job.

The solution is to use the smoke wrench. Heat the rotor cherry red, then give it a wack with a BFH (Big Hammer). Should pop right off.

 

Yep.. that's what I did.
I heated the disc up a ton, and just kept hammering at the disc with a mini-sledge.
Don't forget to keep hitting altenating sides of the disc on order to walk it off, otherwise it won't move....

 

thanks guys i'll go get a torch tomoro and give it a try

 

Before you go and overheat the hub bearings; try this:

Go get some longer bolts and thread them into the opposite holes that were screwed to the hub. then tighten the bolts to "jack" the disc off the hub,

Work smart, not harder

 

Hit them with a BFH like Aaron said and alternate so you work it off.

I also hit my friends on the side where the vents are to try and vibrate it loose.

After my bone head friends spent 10 minutes i walked up and got it off using this method in 15 seconds.

Vibration and force are your friends.

If all else fails then heating will work.

 

Yep, walking it off by hitting alternating sides is definately the key.

 

 

If all else fails, take it to a good parts store/machine shop/repair shop that jhas a press. They will pop it off in a couple minutes with no damage from pounding.

 

With some rotors you cant thread in two 12mm bolts to force the rotor off the hub, there just isnt any threads there. There are even some rotors that dont even have the hold down screw threads. Instead of hitting the rotor, try hitting the hub part of the rotor. And use a big hammer like a baby sledge and not a regular hammer. And thread in the lug nuts so if you miss you wont damage the threads on the studs. Done be a *****, smack it hard.

 

Wrap a towel around a hammer and go at it. A straight hammer will scrape it up pretty bad.

 

just for the record it's Big ******* Hammer

we all like one of those around the shop for variouse job.. maybe even one in the trunk or in the back seat for the odd job

anyways yea walking it off is probably your best bet..

also hitting it at the fins is probobly not the greatest idea and your probably better off hitting in the same direction but where the rotor goes over the hub,, i used a 20lb'er on my fronts a few weeks ago..

If you are replacing the discs who cares about scraping them up.. mine are practically flat from me schoolin' them!

Ya, and the front discs don't have thread holes.... the back opnes do- but they don't always work too well.. just pound away (walking... not on one side...)
