Default Arrrghh broken caliper bolt!!!

Was taking off my scoobyclinic 6 pots to send off for refurb. First came off easy enough, drivers side however!

Bottom bolt has sheared off, top bolt I stopped as it was starting to round. I dont really fancy putting the other side back together and filling with brake fluid to drive to a garage.

Here is the question, would it be easier and indeed possible to remove the complete hub and brake assembly so I can pop it down to a workshop where they will have the tools and know how. If so I guess I need to unbolt the strut, CV and bottom arm??
Is this going to be a half decent way of doing this or am I barking up the wrong tree completly

It is a second car so I do have the luxury of not having to rush out there and do it this instant. Appreciate any thoughts or suggestions.

Best to get the hub off mate and get it to the workshop. Not normally a hard job to do

As said, pop the hub off and get the nuts drilled out professionally if you're unsure - don't want be screwing around with brakes. Worst case they'll need to re-thread the holes and you'll need slightly larger bolts but a half decent workshop should be able to drill out the nuts and just clean up the existing threads

Thanks, that what I was thinking but wasn't sure if it would all come off together. I don't want to keep mucking around with it and make it worse!

I guess once the CV boot is off there is a circlip or similar holding it on??

I love it really, well I think I do

The only reason I brave enough to wield the spanners myself is that if, no wait, WHEN it all goes **** up I've got my daily wheels still.

Get the buggered thread helicoiled. One of my brembo bolts stripped the calliper thread so drilled them all out and helicoiled all 4 holes in the callipers. Good as new now. Better even! Is the trouble with alloy callipers and steel bolts, always happens eventually. If you use a helicoil you can re-use the original calliper bolt size without having to go oversized! Easy job. Good luck.

Thanks for the replies guys. Feel better now it seems I'm not the only one to end up in this sticky situation.

Anyone know of the top of their head what size socket I need to get the hub nut off??

Is their anything special I have to do when removing the hub, maybe disconnect crank sensor, get a remap and do a little scoobynet dance

Hi
You should be able to get the bracket off without having to resort to removing the hubs , the hubs are not threaded where the brackets bolt on , its the bracket that will be threaded , if the bolt is not coming off , carefully grind the head of the bolt off , when you have done that you will be able to remove the bracket and have the left over of the bolt removed , and machined if needed.

You can remove the caliper off the bracket as they are radially mounted , once the caliper is off the bracket , the disc will just pull off , and you can get at the bracket then.

Should be easy to do

Cheers Ian

Thanks Ian, I've got several jobs about the house so I've booked a couple of days off work. I will have a look tomorrow and see whats what.

I actually spoke to your company a while back about trying to refurb these for me. Only just got round to trying to sort it,once the offending article has been sworn at repeatedly and then finally removed I will give you a call to see if you can't help me get these babies working properly again.

edit...

In fact, Ian, assuming I manage to remove it by your method can I send the caliper with the piece of bolt inside and get you to sort the lot?

Cant help you with the sheered bold but here is a little tip for you so you don't round off bolts. Use a 6 sided socket not a 12.
6 sided grips the flats of the nut/bolt not the corners like a 12 sided does.

Hi
Which bolt are you having problems with ?
There will be 2 bolts holding the caliper onto the bracket , and 2 bolts holding the bracket onto the hub , you can get the calipers off the car by removing either set of bolts
Can you take a picture of the offending bolt and I can advise you the best way of removing it
Cheers Ian

Hi Ian, its the one that bolts into the hub. Initially I wasn't sure how the caliper came off the mounting bracket so I went with the hub ones. So I guess I'm probably best taking hub off now?

I just went and had a look at the one I did get off, I see now its attached to the bracket by an 'alan key' type bolt that goes all the way through the caliper.

Thanks for the help, hopefully get it sorted tomorrow.

yes 2 allen key bolts holding the caliper to the bracket , if you get these off , the disc will come of , you can get at the bolt holding the bracket to the hub , you should be able to carefully grind the head of the bolt off , and then remove the bracket with the shaft of the bolt still screwed in , and then remove whats left of the bolt leaving all threads intact so no machining would have to be done , just fit new bolts

Lovely, thanks. Looks like I should be able to get the caliper off easily. I didn't realise the caliper was secured to the bracket this way

Never mind learnt a fair bit by having a go myself which is the appeal for me.

Many thanks for all your help chaps. I took the hub off in the end and got the caliper off the hub.

Ian, thanks again, calipers should be with you sometime next week for you to work your magic on!
