Yep, it's a typical drum brake under there. It doesn't self adjust, because they don't want constant lining to drum contact.


Sounds good.............I edited the title here and put a warning too .

Thanks for the heads up.

 Well i just undid mine from the lever, i want to do it from the hub but what do you mean it has a small spring loaded arm that can be pushed of...i thought it was as simple as turning a screw with a flat head driver...

wow that was more intense than that one time I forgot how to sit down...

Drum brakes have these little spring loaded arms that just touch the gear of the screw to stop it from unscrewing itself. This may not have it but normal drum brakes do.

Just use a screw driver and do the shoe trick and see if you can turn it back if you go too far. Well, try turning it both ways before you get TOO far .

 It has no checkspring on it, just a tension spring that pulls the shoes toward one another. In dedicated drum brakes, there is usually a lever that drops down into the teeth of the adjusting cog, to prevent it from turning on it's own. As our drum is not an active brake (it has no hydraulic component) it doesn't need a checkspring. YOu can rotate the adjuster looser/tighter with just a screwdriver.

 So are you supposed to adjust it with the parking brake on or off?

Also, which way do you turn it to make it tighter? I don't really see any place on the picture where a screwdriver can be inserted.

 Ebrake DISengaged (laying flat).

In the second picture you can see the screw that looks like a little gear. You stick the screw driver in the hole in the first picture when that hole is at the 6 o'clock position and begin to adjust. Turning the gear down should expand the shoes. If you think about how it is in the picture, turning it down will untwist the screw from it's housing and expand it.

 So then what you're saying is that you have to line up that rubber piece in the first picture with the gear in the 2nd picture at 6 o'clock and adjust it with a screw driver. We should never actually take that cover off so that we can see whats in the 2nd picture?

Once we line it up then, to tighten the e-brake, we turn it clock-wise. Is that correct?

First section is correct.

The "cover" you are talking about is the rotor. That little black rubber piece comes off so you can access that screw. And yes, if you're facing the rear of the car, the gear would turn clockwise....if you're facing the front, it's counter clockwise.


Dr_Isotope, please confirm this to be true/false.

 Cool, so while we await doc i's confirmation on that, i'm wondering, how do we get that plug out?

Also, I just realized that that 2nd picture is without the rotor. Silly me. I hope it's obvious though when the screw is lined up at 6 o'clock, that's not the easiest thing to eyeball.

It's just a rubber plug so just use the edge of the screwdriver to take it out.

Yeah, it'll be obvious. I'll be doing this tomorrow night before going to the track to watch, so I'll post up the directions if he doesn't respond.

 I'll be adjusting the brake on another tC come this Saturday, so I'll make my best effort to bust out the Canon S3 and document the process. It is ever so simple, and takes about 15 minutes total.

Oh, and if memory serves, you'll be pushing against the teeth at the bottom; in this case, "lefty loosey" = "brakey tighty".

 Ok, so yeah....facing the back of the car, you'll push it clockwise to make it lefty loosy on the DRIVER'S SIDE......and facing the rear on the PASSENGER side, you turn it counter clockwise for lefty loosy.

Why would we want to make it looser though? Isn't the whole point to tighten the e-brake? We have to loosen that gear to tighten the e-brake? That sounds backwards. I'm just confused because counter-clockwise is counter-clockwise whether you are on the right or left side of the car. Facing the rotor, regardless of which side you are on, the counterclockwise is turning the screw left.

 no, you loosen the bolt which makes it expand. The brakes tighten but the bolt "loosens" in that direction.

 Okay, so i'll loosen it, that's cool. I just edited my last post. I added the part about counter-clockwise being to the left when looking at the rotor regardless of which side of the car you are on, is this correct?


Sorry for my ignorance and thanks for bearing with me.

 If you are sitting on the driver's side with your left arm against the car and looking at the rear, counter clock wise is left...........BUT, if you're sitting on the driver's side with your right arm on the car facing the front, counter clockwise IS left also, but from the other side it's clockwise.

Hard to picture but you'll understand it.

Hold a penny on it's edge with Lincoln facing you. Roll it left. Now, don't spin the penny but get on the other side of it. Now roll it left. From the original side you were on, you're actually rolling it right. Get it? Hope I didn't confuse you

 Heh, I get what you're saying. If you are behind it, counterclockwise becomes the other direction. Alright, i'm feeling clear about this. Thanks Web and Dr. I. Like you said, it should be a quick thing. I never have confidence in myself until I do something successfully the first time - I think I need a shrink!

 damn, forgot to take pics but I losened the cable up and adjusted the shoes in the rear drums.

Very easy....in Dr. Isotope's picture, remove that little black rubber ring, make sure it's at the 6 o'clock position, get a flat head screw driver, turn the gear upwards to begin the process of tightening the brakes. Keep tightening until you feel the gear stop (DON'T OVER TIGHTEN)...just go until the gear stops and the rotor can't turn anymore. Now, push the gear down 2 little knotches to release tension.

do this on the other side and you're done.


I have it set to 7 clicks full lock

 Did this DIY a few days ago. I highly recommend doing it if you've dropped your car. For some reason it gets loose after you lower the car :o

 Loosen the cable..........Dr. Isotope opened my eyes to the problem although I thought it wouldn't happen.

Loosen the cable back to stock. If it's too tight (tighter than stock), you're just stretching the cable until it's taught but the shoes aren't traveling any less to tighten in the drum.


Here's the steps:

1)loosen and return cable to stock (about 13 clicks to full lock)
2)make sure front wheel doesn't move (block in front or behind depending on how you are facing a hill)
3)remove back tire (make sure ebrake is NOT engaged)
4)turn rotor until little black rubber cicle is in 6 o'clock position
5)use a flat head screw driver and remove rubber circle
6)look into the hole and find a gear looking screw
7)use flat tip screw driver and place at bottom of gear and turn gear upwards (this pushes the shoes against the rotor drum)
turn until you feel the screw stop turning with normal amount of pressure (don't wrench the shoes against the rotor drum)...you should feel the rotor imobilized (you can't turn it)
9)when you feel the screw stop, place the screw driver at the top of the little gear and push it back down about 2 clicks..(you will feel the rotor loosen and spin free again)
10)replace little rubber circle and wheel
11)repeat steps 3-10 on other side


Believe me, this is much better than the cable. The shoes are moved closer to the inside of the drum and full lock will be about 6-7 clicks. You will feel the handle still feel loose (but in a good way). It'll tighten completely at 6-7 clicks and you will release the tension on the cable and not risk breaking it.
