Brake Caliper Fell Apart :(

[jimrobbington]

So I drove to work today, and everything was just great. I leave work tonight, and I stop at the first stoplight. As I'm sitting at this light, the brake pedal just melts to the floor. I pull over in a parking lot, and inspect.




the rear caliper came apart, the piston is pushed all the way out and leading fluid. do you think the caliper needs to be rebuilt now?

[sa_seahawker]

What happened to the upper caliper bolt?!

[jimrobbington]

exactly :(

[mec]

did you torque them correctly last time? improper install of something probably, I think this is a first in this forum.

[Charles.waite]

So the slider pin was still there but the bolt holding the caliper to the slider was gone? Weird. Did you use blue locktite?

[jimrobbington]

I guess not. I can only blame myself, since I did the brakes last, but they have been fine for several thousand miles. seems strange that it would come apart now.

I'm wondering if I'll just be able to push the piston back in and everything will be fine, or if the caliper will need to be rebuilt or replaced now. plus I think I lost so much fluid on the way home, the whole system might need to be bled and fluid replaced anyway. fml

[jimrobbington]

unfortunately, loctite was never suggested.

[mec]

That really sucks man. Luckily you're ok and didn't get into an accident :).

Think maybe when you crashed a few weeks ago it made the caliper bolt loose and then repeated braking slid it out?

JR, This is no big deal. If the piston didnt pop out, then they dont need to be rebuild. Not that you would have to anyways if the seals and boots were good. Just push it back together, then add a bolt, and some loctite. To be honest, I have never used Loctite on brake bolts (bikes, trucks, or cars), but it might not be a bad idea.

Let me know if you have any questions. As always, feel free to text me!

Do you have any crazy ex-gfs/wives/baby mommas that have recently taken out a life insurance policy on you?

lmaooo hahahaa dood your an ass hahahaha but i ws thinkin why yellow?? i mean on an audi ... hmm idk..

[B7Joe]

Sucks man. Wow, never seen that one before. My guess is that you forgot to tighten that top bolt. I have also never used loctite on a caliper bolt, but I guess I will going forward. Makes me want to check mine this morning!

Cuz it looks good!



But really, I guess I am just lucky I didn't need to stop when I realized I had no brakes. It was a long slow trip home, but couldn't have done it without a manual transmission. Lol.

You think I will just need to bleed the one caliper or the while system?

Damn people being relentless on the painted calipers JR lol I like em though, but I think it's like Corey said. Looks like everything is Ok and the caliper piston just needs pushed back in and new bolt installed. Hopefully it didn't shear off or some shit. Never heard of that happening before but you never know.

You never opened the system, so basically, you need the tool that ratchets the piston back in (because it is a rear caliper), make sure the pad is still in good shape and there, and install a new bolt. No bleeding necessary. However it's never a bad idea to bleed the brakes! That fluid is only rated for three years max! Water gets into it over time and that makes bubbles when it gets hot which is the same thing as having air in the lines.

Is blue loctite ok, or should red loctite be used?

[Amarao]

So who did you piss off?

[CorneliusRox]

blue would work.

Well if enough fluid was lost so that the reservoir is empty, you really should bleed your brakes as air will have gotten into the master cylinder.

Jimbob, the bolt for the slider usually comes with some locktite style paste on the threads, at least when you buy them new. I would think when reinstalling them Its's a good idea to put a dab of blue locktite.

Red would make it very hard to separate the slider and bolt again so I wouldn't do that.

I just assumed it hadnt gotten that low since it is just one piston and he didnt say anything about the brake light blinking. But this is very true.

[jimrobbington]

Well, the brake light did flash. I checked the fluid reservoir this morning and the level had not gone below the drain tube, so I don't think air has come in from that side.

Anybody got a part number for my missing bolt?

This will work. Unfortunately, I'm not sure you can buy the bolt separately...

[jimrobbington]

damn, I was hoping I could just run to the dealer and get the bolt on my day off tomorrow.

probably cause the system didn't feel back pressure.

It might, but I think they usually just sell them in kits. I might have had one, but I tossed the old ones out when I installed my brakes. Sorry man.

[ddillenger]

Remove the bottom bolt, go to Fastenal or any GOOD hardware store that has grade8 metric hardware and find one that matches.

New rear pad sets from the dealer normally come with new caliper to carrier bolts, and usually they have a dab of threadlocker on them.

I don't stock any rear caliper parts at the dealer I work for, what I always do for customers who need the bolts is just take them out of a new pad set and sell them to the customer, then I order some bolts to throw back in the pad set. If your local dealer is friendly, they may be willing to do that for you.

If they won't help you, go to a good hardware store and get a M8x22 bolt, just make sure its grade 8 or higher.

AAA metric next to i25 and Santa fe. They have all the bolts

Thanks for the heads up on this one. First place I could find that had one in stock.

Ok, so I bled all four corners, til the clean fluid was coming out, and then a few more pumps after that. The pressure will build if you pump the brakes, but if you hold the pedal, it just melts to the floor. There is now SOME braking there, but it is not even in the safe range yet....

WTF?

[CorneliusRox]

You need more bleeding then.

If you still dont have it cleared up after my wedding, I'll come down and help you.

[Charles.waite]

Get a motive bleeder. You might need to actuate the abs too in case there are bubbles stuck in the pump.
