Hi went to change the front discs of my P38 today, as they are doing a very good impression of Rizzlas, but got stuck pretty quickly.
- Can't get the brake caliper bolts out
- Can't get the posidriv screw holding the disc on out
So, my questions that I hope you may be able to help me with...
Re the caliper bolts - they are the 12-sided ones. I only have a six-sided socket in 19mm and of course this won't fit, but my 12-sided 19mm spanner fits OK but won't shift the bolt, even when hit with a hammer. Should I just be using a normal 12-sided socket on these, or is there a special socket I need to buy? I really don't want to round the bolts off.....
Re the posidriv screw - I have a large posidriv bit that fits OK but it won't shift it, and is just rounding out the screw. How do people normally get these out? If I drill it, will it be a right pain to get the bit that's left in the hub out??
Finally - any suggestions/hot tips for pushing the caliper pistons back in without the L/R special tool...?
Thanks for the advice everybody - didn't expect this to be a long job at all (changed lots of discs in my time...) but I am a bit stuck right now....
Best regards
Jerry
