3rd Generation E-Brake

OK before I start, lemme get a few things straight.

I searched the forms before i decided to write this.

I know I have an automatic transmission, so I dont need to use the E-brake.
I seem to have the highschool mentality that in the wintertime, unplowed parking lots are just begging to be drifted in by my 130 hp, FWD camry.

After sliding around a few times, my right rear wheel was sticking, I assumed it was something to do with the E-Brake. So I took it to my mechanic and he told me that my camry has a "Self Adjusting Emergency Brake", something about every time you pull the lever and then release the brake, it ratchets the location of the unengaged e-brake closer to the brake drum, eventually locking up the wheel all the time.

So here are my questions.

Why would toyota design the e-brake to do this if it needed service every 10 times you pull it?

Is there a way I could make it not do this, so I can pull it as much as i want with no concequences?

and is it possible to make the e-brake work for both sides, instead of just locking up the right rear.

If the adjustment components are clean you should never have a problem like this. (This was the mechanism for a Gen 2, I believe that it is the same) Every time that you pull the parking brake lever a lever pushes at a "star wheel", which in turn has a ratchet. Once the brakes wear down enough the star wheel will advance one notch which expands the brake shoes out and "tightens" them. This goes on until the shoes wear out and need to be replaced. The mechanism has a few springs, a cam (star wheel), and levers on pivots. Usually, when they fail they cannot advance the adjustment and the parking brake gets looser and less effective. I don't know how it could fail the other way and tighten it too much but evidently, it did.

If you have to take it in after 10 more pulls, take it to a different mechanic.

Wait... so clarify this... Pulling the e-brake often will result in your rear tires locking or the brake eventually not working?

Does this include when you are just PARKED on a hill and want to pull the brake up?

No, the parking brake does not automatically tighten the brake shoes every time you pull the handle, only as the shoes wear down. If it happens again, there is something wrong with your parking brake, and you should find a different mechanic.

Hmmmmm......that is some very interesting information. Hopefully I will be able to figure out what is happening to my car.

It was a combination of both while parked and while moving on ice.

It seems to only lock up the right rear wheel. Maybe the left side is broken.

Is it supposed to work on both?

The parking brake should work on both back tires.

If yours only locks up the right tire, then the left side isn't adjusting itself properly. That is to say, it's not adjusting itself and taking up the slack in the mechanism. The right side sticking means it isn't adjusting itself properly either. It's over-adjusting itself.
