    Brakes sizes

    Hi people I have just come back into Astra ownership and brought a 2000 SXi (W reg) 1.8

    The dics are getting past their best and pads are low So my questions is What size are the discs on the front and on the back? When i had my 2002 SXi 1.6 i brought some new discs and pads Will these fit on the front?

    Also when i have my 2002 SXi i read somewhere that it sat 20mm lower than standard astras? If this is true will my 2000 one be the same? As this is the earlier model

    If anyone can help me out that would be great Any information will be greatly recieved

    Thanks in advance

    If you have 5-stud wheels Your disc sizes are;

    front discs are 280mm x 25mm

    rear discs are 264mm x 10mm

    If you have 4-stud they will be 256mm x 25mm with drums on the rear

    NOTE: you won't be able to use either the discs or pads that you mentioned you had on a 5-stud car.

    NOTE2: you can easily upgrade to 308mm brakes on the front by changing the disc size and change the calipe carrier from a Astra SRi-T/GSi-T or Zaffira of the same spec.

    As for the springs, yes all Astra Sport/SXi/SRi and GSi had -20mm lower than standard springs

    In that case then yeah the discs and pads you bought for your old SXi will fit.

    I forgot about the 4-stud all disc setup.

    You can also do an OE 4-stud 280mm (not to be mistake with a 288mm conversion) upgrade if you wanted more braking performance. Or even do a re-drilled 308mm upgrade as its the same job for either which involves replacing the calipers, carrier, hub carrier, discs and pads.

    I did look into upgrading the brakes on my escort Brought all the stuff but no garage would fit it Think i will leave the upgrades and just get some decent discs and pads all round

    Any ideas what size the discs are on the back? If the front are 256 4 stud on the front

    4 stud is 256mm front and 240mm rear

    5 stud is 280mm front and 264mm rear (turbo has 308mm fronts)

    Id highly recommend the 4 stud 280mm upgrade on the fronts - using GM parts can be done for £100-150 - its a doddle to do yourself but if ur not confident then im sure a local member would assist you without paying for expensive garage costs.
