Resolved 1G Caliper Bracket Bolt Broke

[spadepro22]

The bolt on the bottom of my caliper bracket broke off and there is not enough screw to grab and try to turn it out. Any ideas of how I can get this out? I think its reverse theads so and e-z out probably wont work.

I had something like that happen before. I Just drilled a hole and if you have like an allen wrench drill it to that size and use that to turn the remainder of the srew out. The most expensive way is to just replace the whole unit if its stuck in there really bad.

They are not reverse threads.

^^ Exactly not left hand threads.

Your gonna need to drill it out & try to get it with an easy out.
Sometimes they're really bad & have to drill them out completely.
Just try to drill it on center as possible, be careful not to break easy out in there too.

Forgot to add another trick I like to use that is easy'

If you know someone with a MIG welder...
Weld the same size nut as the broken fastener on the broken end.
Fill the center of the nut with a liquid pool of metal.
The heat built up will help you use the welded nut to turn the broken bolt out.

Take a wiz wheel grinder and put a slit in the bolt so you can turn it with a big flat head screw driver.Before trying to screw out the bolt,heat the bracket around the bolt with a torch. Done this on many cars in the shop over the years.Very common on some Hyundai ,I used to always heat em from the start just to be safe .

STOP

I just dealt with a similar issue with my wifes SRT4. I spent 4 hours hacking and drilling into a Caliper bracket bolt and it was a complete waste of time. I dont know how the bolt broke but take the car to a brake shop. Let them advise you on either replacing the caliper or allowing them to remove the bolt.

If you play your cards right you can get them to remove the bolt without letting them replace the caliper or the bracket.

I'm confused....a caliper mounting bolt/slider broke off in the caliper bracket, or the caliper bracket mounting bolt broke off in the steering knuckle? One is far easier to repair than the other, obviously.

I think the caliper mounting bolt (that goes through the knuckle) broke off in the caliper bracket. That is what they thread into, not the knuckle.

I would try the trick Wrencher pointed out; I have really good results with that too. Otherwise, just save yourself the headache, and buy a reman caliper with a bracket.

It's not worth it to drill it, and probably end up spending $30-$40 on a helicoil kit and a drill bit to fix the threads afterward.

You are correct- you can tell the last brake job I did was not on a DSM.


Pitch the caliper bracket and buy a replacement....problem solved. The time and money wasted on drill bits and extraction tools will more than pay for a replacement bracket.

Very true.

I am dealing with the same issue. I changed all my brake pads and rotors except for front passenger side.

The two caliper bracket bolts are completely stripped and won't come off.

What you end up doing OP?

I work in process/machine maintanence and remove broken bolts all the time. Best ways of doing it and not damaging anything is to us an air scribe(or electric) its what is used to engrave in objects. You can pick on up at harbor freight for pretty cheap. To get the bolt out just turn it on and put it as close to the outside edge on the bolt as possible and work the bolt in the direction of loose. Next is chisel and hammer which follows the same concept as an air scribe just with a chisel and hammer and alot more arm strength. Then is the afore mentioned easy out, and weld it as some one else about mentioned. I know alot of other tricks but to explain them on here would take pages. If you want to know them send me a PM and ill see what i cant do about making a pdf file with pictures and such

anybody else still having problems with this.
