Broken bolt on right rear brake ebrake cable

[mikedahammer]

Does anyone know the part number for the attached part? When I swapped my rear rotors and brakes the last item to finish up was to tighten down the rear retaining bolt for the ebrake cable and the bolt snapped off inside. I have neve snapped a bolt before and was only going for a quarter turn after it was tight (too much ooga booga I guess).

I tried to drill it out with some left drill bits and a bolt extractor but because i suck and how small and awkward it is I am going to have to replace that part if I want to use that bolt hole.

I have it zipped tied down for now but not sure if that will really hold. Does anyone have any creative ideas to keep that part in place? I even tried a self taping screw but couldn’t get it to bit through the old bolt. Not sure if it comes loose if it is a big deal. It was too dark tonight for a good pic but tomorrow I can get one.

The pic is from the still of a video and the other side of the car if you will see what I am referencing.

Well, this is why I own 6 torque wrenches...

This is repairable, and the way you repair it depends on how damaged the hole is. First, if you're trying to drill out a bolt, start with a tiny drill bit and work up 1/64" at a time. Right hand bits will work fine. Just keep making the hole bigger until there's nothing left of the bolt and the threads come out in little scraps.

If that's not an option, then get a kit from these guys: Time-Sert – Time-Sert +Thread Repair System+ – Kits and Inserts Official Site

Their kits provide a drill bit, an oversized tap and the threaded inserts. I've used them and they're excellent.

If the broken fastener is proud of the hole at all, you might try dressing the end of it with a radiused or cone shaped burr bit in a dremel tool. This way you can get a smooth surface to center punch/get a drill bit started.

It's always hard to get a drill bit started on an angular, rough, fracture surface (at least for me). They always seem to catch and walk where I don't want them.

Good luck if you choose to re-attempt extraction!

Just a couple of bits of advice. If you cannot dremel the top of the bolt as suggested, use a center punch. Keep working it until you have a good dimple in the middle. Invest in a good set of cobalt drill bits. They are capable of drilling stainless and are what you want for that bolt. Work it slowly, and use oil to disapate the heat. As has been stated, start small, and work it in steps.
It will take time, so be patient.
Good luck.
