    Caliper guide bolt probs

    Ok, so I replaced the front discs and pads on my mk4 Astra.....But....
    I have managed to strip the thread not on the bolt but the bracket it goes into.
    Can you give me some advice on how to sort this out.
    Thanks

    If the thread is stripped, then running a tap thru it wont help. I dont know the part involved, but you may be able to get a helicoil fitted. Drilling and tapping the next size up is an option if the holes on the caliper can also be opened up but I wouldn't think that was advisable with brake parts. Other than that, it's replace the offending part.

    Going by seom of the detaisl you provided on ealrier threads you ahve started, it indicates that you have an SXi, so presume is is a 4-stud car.

    If this is the case its more of an involved job than what the 5-stud is.

    The caliper mounts direct to the hub carrier as it has an integral caliper carrier (unlike the 5-stud cars that ahve a seperate caliper carrier).

    You will need to source a replacement hub carrier and then remove the caliper and brake disc. Then you need to remove the hub carrier from the suspension and extract the drive shaft after undoing the hub nut.

    There are then three torz bolts on teh back of the hub carrier to remove the hub off the hub carrier.

    Its then a case of re-assembling all parts to the correct torq settings and re-fitting.

    hi teecee,

    how did you do that? did u insert a helicoil? what type of helicoil? is it M9 x 1.25?

    I heard that helicoil is the right way to do it, it will be even stronger than original.
