Front Brake Pad Pinch Bolt

[Nat67]

Good gracious ! I said small punch not a bloody chisel . It usually takes 3 or 4 points around the bolt head , punching away from the casting . I've done hundreds ! send me the caliper. I will have that out in 5mins and send it straight back to you , cleaned up , de burred and like new . If not , I will send you mine !

plus , since I recommended this method I will pay the carriage both ways!

Paul get a gas cap on that tank or moisture will get in and rust the inside

Started with a small punch technique. No cigar. More aggressive punching... no no. There is not exactly much space to grab the metal you see. Heat + hex wrench, no no. It would cost more to ship the bloody thing than what it is worth. I am not a machinist or a bolt extractor but this one is a mean one. Eventually someone will take it out and we'll see why this happened.

There is another option - used by a mechanic mate of mine when the get a fecked up bolt. They buy TORX screwdriver heads that are persuaded to fit in the hex bolt head with a hammer. And then impact driven out. After that it's drill time.

And they get LOTS of practise. It's a Guzzi shop and Guzzi have taken to using special bolts made of something really soft but grippy. Tighten 1oz-in over spec and that's a seize.

There you go Barba, got me Guzzy bolts on my calipers

I presume the pin is still straight ? If it's bent and snagging the hole in the pads it can't ever wind out !

I was going to suggest that. It's worked for me several times on socket head fasteners

dremeltool cut as much off as you can then with a small drill , drill into the bolt getting larger each time finally with a small screwdriver work the bits out.
