Overtightened brake bleeder valve - what to do now!

On my 2009 Odyssey I hand tightened the rear brake bleeder valve and then used the torque wrench set to 7ft-lb. As I was already at this torque from my hand tightening I did not notice the click and I tightened it almost a full circle

what should I do? Is changing caliper the only option? It is not leaking or anything. I test drove and brake works. I am worried about brake failure.

where to find a good used caliper!

Thanks in advance for any advice!

It's easy to miss the torque wrench click at low settings. :(

Anyway, it's no problem for now.

The bleeder screw will probably break off next time you remove it. At that point, you can either drill it out or replace the caliper.

If you are brave, you could try to remove it now before normal corrosion adds to the bond with the caliper. If it comes out, replace it with a new one.

He probably thinks the brake bleeder will shoot out due to bad overtightened threads and under pressure the bleeder will eject from the caliper. My recommendation is to replace the bleeder with a new one and use anti-seize on the threads. As said, another case it that next time it needs to be bled again, the bleeder will simply not cooperate.

If your bleeder is tight, you are set. But as suggested above, if you stripped it so that it's now loose, you have a problem.

It seals by seating at the bottom, not at the threads.. So, if you tightened it so much that it snapped, you'd be be OK until the next time you need to bleed.

Again, as noted, you can get a replacement starting at $36 from Rockauto if you need it to sleep well.

Thank you for all the replies!

I am not letting my wife drive the van for now!
Bleeder valve did not break loose or leaking. It is staying put. I did a test drive and everything is intact. My worry is when break heats up will it break and come off
Any video on replacing the bleeder valve? Does that mean I have to drain all the brake fluid first?

Replacing the bleeder valve just means unscrewing it all the way. You obviously unscrewed it part way. It's just like unscrewing a bolt or a screw. And replacing it. No need to drain, just have the replacement close by. It'll drip out, not gush like when under pressure. Just replace the teaspoon or two you lose if you are slow.

Did anything feel wrong when tightening the bolt? If not, I doubt it will fail on you. But you need to decide if you want to take care of this now or later when you service the brakes again. If it was me, I would go back and untighten the bleeder valve. It's either going to come out as usual or break. It should be fine and then you can just torque it to spec.

Buy the correct bleeder. Unscrew the old bleeder. A little brake fluid will come out. Put in the new bleeder. Bleed the brakes. You are done. No need to drain brake fluid.

Normally things like this bother me as well but even I wouldn’t worry. It’s fine until you try to remove it and I’m gonna guess your still gonna be ok.

Same, I would drive it as-is, maybe check back in a couple of weeks to see if there's any leaking. If it's not leaking, I doubt the bleeder is just going to fall out.

Otherwise, let it go until the next brake service... maybe it will be fine, maybe it will need a rebuilt caliper for $50 and at the next service you might want a new one anyway.

Kunju, your brakes are fine, and if you haven't seen any fluid coming out of the bleeder, you will never see fluid.

The only thing you've done is overtightened the bleeder, and if it didn't break off when you applied the over torque, it never will. The only downside is that the bleeder will probably not come out again, and I'd just replace the van before you have to do the brakes again!:)

The trick I've always used to get out stock brake bleeders is to spray it with WD40 and let it sit for several hours or over night.
then after the time has passed, get a drill bit that fits snuggly into the bleeder valve hole.
You want to put the smooth part of the drill bit into the hole, not the threaded side, it needs to fit very tight, tap it in till it bottoms out.
The drill bit will stop the bleeder valve from squishing and deforming.
Now you can put a wrench or vise grips onto the bleeder and twist it out.

Replace bleeder valve with a new one.

But as others have stated, you do not need to replace it now, your brakes are good till next time you need to bleed them.

There is that torque value for the brake bleeder, but you should not use a torque wrench on the brake bleeder screw. It's never accurate due to brake fluid between the bleeder screw thread and the caliper. You actually tend to over-torque using a torque wrench on a bleeder screw, use hand to tighten by feel only.
