E-brake replacement, 1998 V70 AWD

terrencekeenan · Post by **terrencekeenan** » 23 Jan 2007, 21:12

I had a loose e-brake. My first problem: I initially tried tightening the cable near the console, but in adjusting the e-brake cable near the console, I went for the torx screw, and the other side which anchors the screw (a lock-ring of sorts) turns along with it, thus proving impossible to adjust. I can't get anything to hold that lock-ring.

The real crux of my problem was an emergency brake that had no holding power. I would pull it, and it would hold very slightly. When I would release it, it obviously wasn't releasing enough because I would hear a scraping sound in the right rear wheel.

Finally, i took it to a shop for diagnosis, and they said my e-brake shoes needed replacement. I didn't have them do it. In driving home, I heard a large clunk several times. I took off the right wheel, and found a broken rotor:

Maybe someone knows how this could have happened?

Anyway, now my real problem is getting on the road again. I have the new e-brake shoe on the right installed, yet the rotor will not fit over the new shoes. Ideas?

And I thought mine were bad.

You beat me!

How are those new drilled/slotted rotors?

I once rebuilt the parking brakes on my 440. In the pic above you see an adjustable part (with the strange wheel thingie and the spring above) - Did you try to adjust the pads with that? I think that's the way to do it...

I missed that part after looking at your busted rotor. First thing is to make sure that the new shoes are properly installed. The bottom portion of the shoes are prone to not seating into the actuator properly.

Here is a picture of what they should look like when installed correctly. Not the relationship between the bottom of the shoe and the iron casting on the hub.

The only other thing is, as was mentioned, is to make sure your star adjuster is all the way in. The rotor should go right on and then you can adjust it through the hole in the face of the rotor.

I had the star adjuster all the way in and no luck getting that rotor on.

If the brake shoes are less than 1/8 inch out of place the disc (rotor) will not go on. It is usually a case of trial and error to get the shoes exactly right. Offer up the disc and see where it is catching then gently tap the shoes and try again and again until it goes on.

This was a problem we had in the good old days when all brakes were of the drum and shoe variety

Yeah, I still can't get those rotors over the e-brake pads. I'm pretty darn sure that everything is situated correctly. It's close enough to where I could probably hammer those rotors over the e-brake shoes, but then the e-brake at it's slackest would be burning up against the rotors once I got moving (correct?).
The adjuster is at its loosest. I was thinking that actuator itself, attached to the cable, might be too tight, but still, the cable is adjusted from the console to its loosest point.
I double checked the parts, and the shop gave me the correct ones.
Ideas why I still can't get those rotors on?

Terry,

Can you take a picture of your brake shoes from a couple of angles looking towards the top and towards the bottom of the shoes and post them? If we can see what you see we can likely be more helpful.

Terry,

Another thought occurs to me. In your original post you talked about adjusting the center console adjustment but it sounded like you had no luck with it. Maybe you did. By the way, it takes an allen wrench instead of a torx.

Try slacking that adjustment way off and then see if you can get the rotor back on. From there adjust the shoes to a "just touching" condition and then go back and re-tension the cables from the center console to get the brake to set within 1/2 or so of the travel on the parking brake lever.

Thanks for your input Lee.
At the console, I did loosen the adjustor. After, I disassembled the e-brake shoes I installed, then tried playing with the cables, trying to slide it in and out to see if it wasn't bound up. They didn't budge. So I went to the console again, and grabbed the heads of the cables with a vice grip and tried to see if I could get some play from that side. Didn't work either.
So possibly, if the cable is indeed bound up inside, the actuator is still in the position it was when it had to accomodate the old worn brake shoes. Could that be the reason I can't fit the rotors over the new shoes?
