    What a PITA the rear brakes are!

    I think I am quite a good hands on person when it comes to cars.

    Decided to change the rear discs and pads which I have done on loads of cars but these 8mm hex bolts on the carriers are a PITA to remove.......I failed and had to put it all back together.

    I have read you can turn the hub to a certain position to utilise a notch on the back of the hub mount to slide the disc out so will have another go when I can...........any other ideas welcome

    Try Irwin bolt extractor. If bolt isn't rounded, them hammer in decent quality allen bit and use extension to lever.
    Is that with or without VAT?

    Errr - I'm no expert, but surely that won't do a torque wrench much good? Just get a breaker bar and possibly add something like a chunk of scaffold pipe to give even more leverage if necessary.

    +1 for the irwin bolt extractor.

    Did mine a few years ago & had to use the irwin to get the job done ( only needed to do the top bolt & bash the carrier with a rubber mallet to move it n inch to be able to get the new disc on) & new bolts from Audi were only a couple of quid.

    On my B7, I manged to get the old disc out without removing the carrier. Took a few attempts and some hammering, but they were getting replaced anyway. I used them to see if i can put them on again without too much damage. They do go back on, so I put on the new discs with the carrier still in place with 0 damage. They kinda rotate in. Cant explain though, but they can go in and out with the carrier there!
