Ok...the drum is rusted on and I have been trying to beat it off for over an hour. I know you can insert a bolt into the two holes on the drum and it will pop it off. Question is: What size of bolt do I need to use? Where can I get one quickly? Will the same bolt work on all drums for the most part? How about rotors? If not, what other sizes should I get?

Thanks,

You didn't specify the make or model of car. It's not a 4Gen Maxima, as 4Gens have 4-wheel disk brakes.

In general, the bolt size for forcing off disks and drums is 8mmx1.25. Please refer to the Chilton repair manual (page 9-11).

Where to get one quickly? This is a common size metric bolt. If you have a metric faster junkpile like mine, you will find many of them there. If not, try your nearest auto parts store or auto dealer (any make). Home improvement stores carry nuts and bolts, but I don't recall seeing metric hardware there.

Put a drop of oil on the bolt threads and tighten them 1/4 turn, alternately.

 

92 Chevy Lumina 4-door....thanks.

I have to think that one size fits all, but who knows.

 

It could be either metric or SAE with Detroit iron. That's what I hated with my Ford. Once I had to remove the gas tank to replace a fuel pump. It had 5 bolts holding the metal shield in place; 3 were SAE, 2 were metric!

 

The fuel pump on a 4Gen Maxima may be replaced from inside the vehicle, without removing the fuel tank. That's an example of design for serviceability, a subject too much neglected by automotive engineers.
