Exclamation Rear brake anti-rattle spring broke; is it vital?

Well, the subject pretty much says it...one of the anti-rattle springs on the right rear brake setup just broke. Is it critical to have, or can I just leave it out for now (I want to get the rear end of the car back together tonight; if I leave it off, I'll re-do it next time). I'm spraying Permatex Disc Brake Quiet on the back of each pad, BTW...

A quick response would be appreciated. Thanks in advance!

...anyone?

Sorry if I seem anxious or pushy; I'm waiting on an answer to this so I can either get the rear brakes done or clean up for the night.

Thanks again!

Anti-rattle wire

You are talking about the W-shaped wire, right? From my experience:
1. Most of the braking is from the front wheels. I've driven cars with siezed rear calipers and only noticed a small difference after the rear calipers were made functional. However, in an emergency stop they are vital.
2. I've seen cars driven with one rear pad hanging by one pin. So the wire was not engaging the pad at all and the operator did not comment on sound or performance.
3. If I were in this situation, I would use the good wire on the left side of this caliper. This pad first contacts the rotor on this side on the right rear when the car is going forward. This will help to stabilize the pad.
4. Install new hardware at the first opportunity. In my opinion the brakes are the most important feature on the car. When I get a new car I always rebuild the brakes first using new components and then move onto suspension and performance.

Hmm? Maybe the ATE calipers are different, but on my Bendix calipers, instead of having one spring on either side, I've got one on the top and one on the bottom.

Given that you made it sound pretty critical, I guess I'll wait 'till I can get the spring...ugh, the car'll have been down for a month before I'm done

If you are sure its just an anti-rattle clip, then no, it won't hurt anything. I drove my 300D for a long time without them because the car was like that when I bought it - whoever did the brakes the last time conveniently didn't bother to put new ones on. It took me a long time to figure out why my car rattled every time I hit a bump, but eventually I discovered it was the rear pads rattling away. It was an annoying sound, but it didn't affect the car in any way.
