Calliper bolts

[Woody2000]

Got one side off ok started on the other side bolts stuck fast !!!

got the top one loosened but now it won’t come out just turns both ways without coming out any ideas how to get it out and what damage 

bottom one won’t turn at all 

Any ideas 💡?? Thanks Mark

An impact wrench will sort out the non-mover; if you do't have access to one then heat and penetrating oil - not both at once - will help. For the other one you've possibly stripped a thread, so it will need outwards pressure as you rotate it in order to remove it from the upright. Does it move far in both directions ie spin round freely, or just a slight movement one way then the other? If this is the case there's hope for the thread, but if it just spins freely then it's badly stripped so hope it's the bolt and not the upright that's lost the thread. Hopefully you'll be able to retap the upright but in any case I'd replace the bolts for the benefit of new threads.

Yes Colin so do I !! Top one turns quite freely both ways bottom one have tried wd40 etc over a few days will try some heat thanks for your help

2000 calliper bolts seem to do that spinny thing, it is to do with the backplate and corrosion on the bolts..

use a smaller spanner as a lever behind bolt head whilst turning the bolt.

Will pop straight out.

Trouble is can’t get anything behind the head to lever it

Hi Woody

hammer a screwdriver blade under the head. The head can't be perfectly flat - it will go.

Once the blade is in turn the head - it will come out.

has the bolt disengaged the caliper at all ????   or its all firmly bolted up   ????

Pete

[Woody2000]

Firmly bolted up still

[Pete Lewis]

so looks like one is seized and one  is  stripped   ...ouch !!

Quick update use a blowtorch bottom nut came undone but top one still not out cant get anything behind it at all tried everything  so I now think I might have to take the whole leg off is this quite easy ??? Never done it !!!

[Pete Lewis]

yes dropping the whole strut is easy,  do not undo the big nut in the top mount or this will release the road spring and possibly some fingers and a black eye 

if you do want to check the top metalastic mounts  strut top pivot bushes you must get a spring compressor 

if you dont want to drop the strut off the lower control arm drop the control arm inner bush bolt and leave the whole unit as assembled

If dismantling do not lose the camber shims. Note where they came from.

[Pete Lewis]

bit out the box could you drill and  tap the bolt head and use stud and old socket to make a drag

Thanks for all your help and answers 

so to get the strut off with carrier ,calliper etc undo the top three bolts at top then not sure what else to undo to get this off haven’t really done this but am gonna try !!

Can you get access to the rear of the bolt? Putting pressure on the end that you can see whilst unwinding at the head end sometimes gives the outward pressure you need to start it moving. Even just a few good whacks with the end of a smaller bolt placed against the end of the larger one you're trying to release and a hammer can move it. It wouldn't be the first one I'd used the point of a two-legged puller to exert force - is there enough access for something like that? Can you grip the head in a set of grips and pull outwards as you turn?
