Rear rotor removal

Is there any special procedure to remove the rear rotors to replace them? Im just wondering cause of the drum style parking brake setup on the rotor. Thanks for any help.

Nothing fancy...you might have to cut a few retaining clips off of the lugs, but that should be all

If the rotor is stuck, you should use a slide hammer, with the hook in the vent slot on the side of the rotor, to free it

Just curious...why are you pulling them off

You will smash the he!! out of the flimsy parking brake shoes if they've worn a ridge into the hat of the rotor. There is a star wheel adjuster to back off the shoes a bit for rotor removal.

Joel,

I don't think I've ever looked...Can you get to the adjuster on these with the rotor on

Have you seen these drum-in-hats score the hat to where the rotor will not come off...usually they stick to the hub assembly b/c of rust

I've had it happen on other rear disk brake vehicles. Havent had to do my 2005's brakes yet. Usually there is a rubber plug covering the adjuster hole on the inside of the backing plates.

Access

Look carefully at the backing plate. It may have a relief stamped into it where the hole is located. If it does, then you have to punch/pry the slug out to access the adjuster. After the first access, you have to install a rubber plug. I've seen this done before on other newer cars I've owned. Seems to be a cost cutting measure. If they can save a dime, they will....

If you look at post #12 in this thread,




(thanks LMMJ)

...it doesn't look like there is any way to access the adjuster w/o removing the rotor

I actually appears that the adjuster is mounted to the backing plate like a rear wheel cylinder would be on a drum brake system

Good call! I remember that pic from awhile back. Sure does look like no access thru the backing plate for that bad boy.
