Disco 1 Sheered caliper bolt!!!

Right then iv sheered one of the main caliper bolts on the caliper mounting. Iv got the caliper off but its sheered flush with the mounting bracket. All i need to know is can you buy the mount or is it part of the axle?
Iv tried all things drilling etc and its just fubared.

part of the axle case, a decent drill like cobalt will tackle it

Cobalt drill bit, low speed steady pressure. DO NOT under any circumstance use an high speed drill. You will knacker the drill bit and harden the bolt.

Right thanks for that mate thats all i needed to know.

What if i cant get drill it? Whats my next move?

You will have to drill it. Maybe 6 or 8 mm for a decent easyout. Heat let it cool, heat let it cool gentle heat. Plusgas and an easyout. Plusgas burns so be careful.

To make you feel better. The same thing happenned on my car and the mechanic drilled it out in about 15 mins. If I remember correctly it is drill slowly, with a good quality metal drill and use a lubricant to keep it cool such as oil or fairy liquid , I had bought cheap bosch drill bits in a set and they were rubbish. i thought how can people drill with theseand get metal out so decided to buy a better brand and they just cut through the metal bolt like butter. I would recommend using gloves to prevent the turnings going into your skin.
I also now have a bolt removing kit in the house that i purchased just in case of emergencies.

Brilliant cheers for the advice ill get cracked on tonight.

Making sure the drill stays lubricated is important, as it helps prevent the drill overheating. If it does the drill goes soft and the bolt goes hard, preventing further progress..

Iv got some carbide drill bits and some cobalt ones now and some cutting fluid so should hopefully come out. Im gonna have to re tap it maybe to an m10 or m12 if this does not work ill just have to nut an bolt it? Will that be ok?

if you do it right there will be no need to drill it larger and "nut and bolt it"

do it correctly and if it all goes tits up, replace the damaged part. Dont bodge it...

Especially on brakes!

yeah, but thats a proper engineered solution, (or a timesert)

no cheap bolts from down poundland!

Yep Halfrauds specials are out of the equation.

Let us know when you have drilled it out.

All done used a densimet drill bit to get the old bolt out, finished with a carbide drill and helicoiled to an m12 all good now. Thanks

Well done. A nice end to a post.
