w202 rear brake disc/drum
 

Hi All,

I have a problem: I cannot remove the rear disc on my 2000 W202 touring. I obviously have removed the retaining bolt and I have loosened the brake shoe threaded stick inside the hub. It seems that the disc is rusted onto the hub in or around the middle. Any ideas? Someone recommended torching. What torch should I use? Where should I torch it? If torched, does the wheel bearing grease need to be replaced?

Thanks,

Greg

Big hammer

Tried the big rubber hammer (I do not want to damamge the disc); won't budge. I guess I will have to use a propane torch to heat it up around the hub.

Is it a drum or a disc?

If it's a drum, you need at least a 4lb sledge hammer (a rubber hammer won't loosen anything - especially anything wheel related), and you need to smack the bejeezus out of the drum squarely between the lug bolts. Use the lugnut tightening sequence, and keep hammering it until it comes off. I've had drums take half an hour & two techs to get off before - it just takes persitence.

Oh, and you are striking the outside-facing portion, correct? Never hit a drum on the edge or "from the car outwards".

it's a disc/drum; it is more like a disc. I tried hammering the part where it is attached to the hub with a regular hammer as well.

BFH = Big F'ing Hammer.

You need a BIG hammer - not a rubber one or a regular framing hammer.

Whack the middle around the hub and put some effort into it.

What he said. Using a regular hammer on a drum is like using a squirt gun to put out a house fire.

Just pony up for an "engineering sledge" or something similar and pound away - you can probably find one for around $12 at your local hardware store. And go for a MINIMUM of 3lbs. 4lbs is better. Remember, the more weight, the less effort it takes.

D) all of the above
 

Plus a can of Liquid Wrench to lube things up before you use the hammer. LR, torch, BIG hammer, as close to the center of the hub as possible.....took me 2 hours
