    The difference between VXR rear brakes and the Astra G rear brakes- pics

    Managed to find a set of VXR brakes on E-Bay for a decent price. After selling my Brembos I was finding the braking a little less than I was used too even with Tarox discs. So I thought I'd upgrade all the brakes to the VXRs which I'm thinking may help.
    The brakes were advertised as just the discs, calipers and pads, the hoses had been cut ( I wish scrapyards wouldn't do that as it's just lazy and you need the front hoses off the VXR due to the banjo bolt being much bigger ) Anyway I managed to convince the seller to supply the rear steel brackets off the VXR as well as I was convinced they were bigger than the Astra Gs and how right I was.
    Here's a quick pic to show just how much more robust the VXR bracket is compared to the Astra G

    Not only is it taller but it's substantially thicker and broader too.

    I've now got 3 front calipers and 4 rear calipers so if anyone would like to buy a set of VXR rear calipers and a single front caliper they are for sale. No discs I'm afraid unless I decide to buy new ones instead of fitting the ones I picked up today.

    Oh and just recieved a set of stainless braided hoses from Courteneys today, full set all 6 hoses to fit the VXR. Funny thing was the kit was missing the banjo bolts and it's advertised as including them, they are looking into it for me.

    The discs, calipers, pads and rear brackets cost me £210. I had to pay another £90 for a set of braided hoses for the VXR, I could have just got the fronts for about £40 but I wanted the full set including the ones above the rear beam so I decided to splash out a little.

    A new set of VXR rear discs are £60 trade and fronts are £138 trade, not sure whether I'll buy new or stay with what I've got.


    As for what else is needed, nothing else except fitting and bleeding etc.

    Just the rear brackets in the pic above. The hoses are the same and I'd say the calipers wouldn't need spacing like they do when your trying to fit MK5 calipers to a MK4 as you'd be using a set of MK5 brackets.

    Looking for £50 for the VXR rear calipers or £80 with the rear discs as well. The brackets can be found quite easily as it appears that most sellers don't remove them as they don't know they are needed, if you can get in quick when a VXR is breaking then you can buy them for a modest amount.

    The Zaffy brackets whilst looking identical are in fact the same height as the Astra G at 135mm, you need the taller brackets from a VXR to accomodate the 278mm rear discs. I'll measure the height of the VXR brackets so you can compare them. Unless of course the Zaffy B is running the 278mm rear discs like the VXR.

    A pic makes it so much easier to explain doesn't it
