I tried changing my pads and discs on my 1.4GP Punto Evo a couple of weeks ago. When I came to removing the calliper bracket, I couldn’t seem to find the right tool. I’ve attached a (admittedly bad) photo of the bolt in question.

If anyone can advise what this is, and what socket I’d need, I’d be very grateful!

Thanks

On the left is external torx, the right looks like a hex.



External Torx



Hex

7mm allen key probably..

Yes thats an ODD size..
The mk2 punto sporting certainly used those

If in doubt just take off the 2 E16 calliper bolts and remove the whole calliper, the design of your calliper is different to the design on my evo

Video of my car here for reference.

Thanks for this! Successfully changed my pads yesterday. Tried to change the discs but the alignment bolts were all rounded off. I didn’t have a drill to get them out either. Any idea what screw and length these should be for when I come to replace them? The Haynes service manual proved useless as ever

In the past when this has happened I just cut a slot in the head of the bolt with a dremel and undone them with a part flat screwdrivers (doesn’t matter if you nic the disc as you’re replacing it.

That way you can reuse the bolts again after

I wouldn't bother to replace the alignment bolts since I don't think they do anything but make installation of the discs a bit easier.

They stop the disk spinning when you try to align the bolts when changing wheels.

They are a european car thing many cars don’t usually have them

The Teves style caliper has a metal retaining spring on the front, whereas the bosch style doesn't. The pads are completely different too (as I found out by ordering the wrong ones :bang.

Anyway, is 51794407 the part number for the E16 bolt? I want to replace mine as they're really corroded. Thanks

Click to expand...

Clean faces.. then install bolts

The discs remain true to the hubs until released..

Loose discs rattling around at wheel changes can sit poorly..
Effecting both runout and potentially torque values
