    Rosie is due her MOT at the end of this month and my hand brake is knackered, so I thought I would replace all the brakes.

    Ordered this lot off eBay for the princely sum of a few pennies over £125. Came from 4 different sellers including delivery, ordered Wednesday afternoon. Last package arrived just after lunch today :)

    Nice. I felt the discs today and all have about 1-2 mm lip on the outside perimeter of the disc. nor sure if this is too much of an issue as the breaks work great, no noise little dust.

    Will you install the items yourself Gaz?

    I don't mind doing brakes myself, as long as the weather is OK as I don't have a garage or covered area to work. The hand brake shoes were a pain in the ass to do on my last Z3, but fingers crossed it shouldn't take too long.

    Main reason for doing them all round is that the discs are currently in poor visual condition but work fine. I'm going to try and put a coat of paint on the calipers as well while I'm in there, so will tidy up behind the rims quite nicely. I have relatively thin spokes on big wheels, so it's easy to see how nasty they currently look.

    Going well so far with the wheel off (sarcasm alert!)

    This is the nastiness and why I'm changing the fronts even though they are likely to pass the MOT :dead:

    Jacked up fine on the trolley jack, with a spare wheel tucked under the side sill just in case of failure. If the trolley jack fails, I don't care what damage it does to the sills or to the wheel as long as it doesn't land on my foot.

    From this point everything is pretty much seized. The bolt holding the disc to the pad gave way eventually. The 2 caliper bolts were hard work, and to remove the carrier bolts I had to turn the wheel hard lock and put a 3 foot metal bar on them.

    The disc was well and truly stuck on the hub, but after some ill advised removal techniques I shall keep to myself eventually came off.

    In the true spirit of the Halfords workshop manual, fitting is the reversal of removal. Yeah? Just trying to work out if my caliper is knackered and the heavens opened up. It never mentioned that stage in the book... :facepalm:

    Now waiting for the rain to stop to see if I can move the caliper back in again or not :bookworm:

    You've been Allen screwed mate........ 5mm if memory serves!

    Did you use an impact driver Gaz?
    Failing that if you don't have one, before you try undoing it beat the area around the screw head with a hammer.

    Nope, it was like soft cheese. That was three attempts with the correct size Allen socket bit. I then tried driving an old Allen key in there, but just not enough left for it to grip.

    I also stopped at this point as I have no screw to replace it with should I get the b***** out anyway...

    Any ideas if Halfords sell the bolts, because I'll need to drive there carefully tomorrow and get a replacement in case I manage to get it out! Or I may just give up and see if my local tyre centre will sort for me...

    What I would do Gaz is get the B.... out change your discs and pads and put the wheel back on and drive as normal to get the screw and fit at your leisure, many cars don't even have grubs screws in disc at all. GSF a better bet than Halfords but if you don't have an impact driver it's a good addition to your tool set. Have never failed to get one out using the afore mentioned methods. Beat the s...t out of it then use impact driver. Simples.... but it is what I do for a living lol.

    Don't worry about the bolt Gary, it is just there to hold the disc whilst the wheel is off, once the wheel is back on the disc will not move.

    If you have an old flat head screwdriver or small chisel use that and a hammer to rotate the bolt.

    Edit: if I were closer I would offer to beat the s@*t out of it for you.

    If beating thes@#t fails just drill the head off 5mm bit. As Brian says it is only there to hold the disc on whilst the wheel is off.

    Gary, happened to me, just drill it out with a 8mm drill, replacements are pennies from the dealer, they replace a lot of em! All explained in my show case ;)

    So having invested in an impact driver, I now have a perfectly cylindrical hole in the top of the screw :banghead:

    Will have to try and borrow a drill to borrow and bore the b***** out :meh:

    Gaz, if you use an 8mm HSS drill bit dead centre, once you get below the shoulder you should be able to pop the head off, once the disc is removed you can unscrew the remainder by hand or use mole grips

    Sorry mate, I did mean for future use as once they're round you are reduced to drilling the top off as Zedonist says. :(

    Nah it was worth a try @t-tony, there was a bit of the edge left so it was a 50/50 gamble on my part... :facepalm:

    Was just moaning aloud as you do!

    Thanks Gaz I didn't want to think you had got one for no reason. If you were nearer I would have gladly done the job for you too.
