    Back brake callipers - pad retaining pins

    I was about to change my rear pads on my 2015 SE. 

    First retaining pin - undid with normal effort
    Second pin - not any movement - Allen head now rounded out.

    Tried removal tool - nope
    Tried hex bolt tapped in - nope
    Tried a bit of heat and penetrating oil and combination of above - nope.

    Any suggestions or does anyone have a spare rear calliper they would like to part with.

    I would advise you dont use Easi Outs. In my experience as an engineer, they should be prosecuted under the trades descriptions act and be called "hard ins"!
    If you want to take the caliper off and send it to me, I will have a go at getting the pin out. I have a fully equipped machine shop, which other members may confirm for you.
    I just rebuilt the rear caliper on my trophy with new seals and stainless pistons, only to run into the back of my mate on the way to France. I knew I should have kept that caliper!

    That would be awesome. 

    My problem is I commute to work on it twice a week ..  not being pushy but how long would you need it for?

    I looked at a new calipers and crapped my pants at 660 quid!
     
    Itís really annoying as I think there is only about 10 turns of the thread that holds those pins in

    If you get it to me with a pin, I will do it the same day and post it back. You must accept that I may not be able to get the old pin out, but I do have a good success rate!
    If you type in "meningitis" to the search bar, there are some photos of my workshop and some Trophy parts I made, just so you can satisfy yourself I'm not working with a 5lb mallet and blow Torch!

    If you take the caliper off, wrap some cling film around the banjo, then insulating tape to prevent fluid leakage. That way prevents loss of brake fluid and enables you to re bleed the caliper without having to open the ABS valves with a dealer tool.

    Hello.
    I had the exact same issue. A 20 min pad change turned into a nightmare. I removed the caliper and my buddy helped me remove the pins, as both has seized and rounded off when I tried to remove them. We used the 6mm bit from this set. Held the caliper in a bench vice. Used a penetrating fluid first. Tapped the bit into the pin, so it cut into the metal, and used a longer handle for more leverage. This worked a treat.

    Good luck :)

    This is the set my buddy has.

    A Torx bit slightly larger than the rounded hexagon can also be used to good effect.
