Rear Brake Carrier Mounting Bolts!!!

Andy Douglas · 17-08-11, 11:45 AM

What the best method of removing the rear brake carrier bolts, the hex.head ones that hold the carrier to the strut!! all friendly attempts have failed

mine's a 90q but they are all similar.
Thanks Andy

I've never had a serious problem with them - you have to be careful to clean the head out, then hammer the driver in and put a wrench on. Did four on a car last week.

Otherwise angle grind the head off.

Another little trick is to grind the chamfer off the very end of the driver to create a sharp edge. The the driver will scrape the rust off as you tap it in. You can pull it out, get rid of the rust, and tap it in again.

you can also try to hit the head of the hex bolt from the side, give it a few hard knocks then hammer the driver in and off they come.

You'll need new bolts afterwards but sounds like you need them anyway

You won't get them on - there's no clearance for anything fitting AROUND the head.

I use these things as hammer-on sockets - no idea what they're called:

But they're only 1/4" drive - even the 3/8" one won't go on. Not very good for an undoing torque often over 120Nm.
