    • Remove the cap from the brake fluid reservoir and set it aside.

    • Read before continuing (photo courtesy of katerha).

    • There are two different methods for removing the brake drum on the Focus. One removes both the drum and the rear wheel bearing, and one removes just the drum.

    • If you are replacing the brake drums, then follow the appropriate directions for your replacement part: with or without the bearing installed. If you are not replacing the drums, keep in mind that the rear wheel hub bolt that holds the bearing in place must be torqued to 175 ft-lbs.

    • This step is for removing the brake drum and the wheel bearing together.

    • Pry the dust cap out of the brake drum with the flat head screwdriver.

    • Remove the 29 mm rear hub bolt nut from the brake drum. This will require either a breaker bar or an impact wrench.

    • This nut is torqued to 175 ft-lbs, and should not be removed more than four times. Use a permanent marker to make a mark on the nut each time it is removed.

    • If you removed the brake drum by itself, reinstall the four retaining bolts on the back of the hub assembly.

    • Torque each bolt to 49 ft-lbs.

    • Place the cap back on the brake fluid reservoir.

This guide should also tell you if you are installing a new drum to remove the abs sensor ring from the old drum and put it on the new one. I threw my old drum away without knowing that and now my abs light is on.

Samuel Sedlak - Responder

Very true: I was a given a 2005 Focus with a glowing ABS light and when I pulled the drums to inspect, sure enough: whoever replaced the drums neglected to install the sensor rings.

Ian Wright -

And a little confusing because you mention removing the drum by removing the hub, but you show the spindle of the rear hub in place in all the pictures that follow the removing of the drum!

Here another how to that shows hub removed in case anyone else is as easily confused as me!

Is there any adjustment of the shoes?

If after four king nut removals, would Loc-tite red be adequate? Use Loc-tite blue within the four-time tightening limit?

I'm personally not sure grease is a good idea. Dust, grease/oil and don't mix well; they usually stick, more, shortly after. I don't know if this is accepted now or not. The intent is recognized, but I think the heat should also make it run very shortly.

You can easily sop up fluid from the master cylinder (m/c) with a paper towel; it's usually very little needed.

The instruction may want to add to add fluid to the m/c after pressing the brake pedal and setting the shoes.

I've never heard of drum brakes being "noisey".

Looks similar to 2008 also.
