epic breakage what to do

goodNIGHT · 06-14-2016, 07:57 PM

ok what did I just break? this is on the inside of the rear caliper

Brake pedal pressure feels okay and there was no problems on a test drive

you sheared the head off the bleed screw

it'll most likely be fine until you can have the remainder removed and replaced

Take it to a professional that can remove it. Otherwise you're left with a $500 paper weight.

Replacing the caliper or just the remainder of the bleed screw?

Thanks guys. I confirmed with the mechanic that I basically broke the bleeder screw itself. They're gonna try to get the remainder out. Let's see what happens.

Uridian · 06-17-2016, 10:02 AM

Out of curiosity, how did you manage to do that?

Tpeterson · 06-18-2016, 06:42 PM

I'm very interested too.

Bleeding brakes, but you were tightening when you think your loosening

Or you were taking the wheels off and it caught at the right angle. 20+lbs on that little aluminum nub .

I took it the mechanic shop and they were surprised to see how torqued in that screw was. Ive never sheared a screw like that either thats why I was like what just happened here??

They couldn't get it out with an extractor, or drilling it. Finally, they hammered a long nail in there and twisted the remainder of the screw out. That sucker was in there

OK, but HOW? inquiring minds want to know...

Couldn't have been bleeding the brakes if at the time he didn't know that's what that nut was.

And I don't see how you could possibly hit that with the wheel with it being on the backside of the caliper.

I'm super curious!

Use a left hand drill bit and you will get it out without too much drama. We have done that many times for local guys when they attempted to bleed their own brakes. It happens.

I bleed yesterday (235) and my front inboard bleeder on drivers side had an incredibly tight bleeder screw that wouldn't budge with an 11mm combination wrench. Wish I had a flare wrench. I couldn't get my regular 11-mm socket down on to it, didn't have a deep 11mm, and not so sure there was adequate room for a ratchet handle. Used a little PB-Blaster and to get leverage did a little trick with interlocking two combo wrenches ( posted pic in Maintenance section yesterday )
But that inboard bleeder was extremely tight on both front brakes, the outboard bleeders were not as hard to loosen. I can imagine the bleeder snapping from stress it was so tight, highly unlikely, but in an unusual event can see it happening.
