Seized caliper carrier bolts...which Irwin bolt-grip set to buy?

[Callum_K]

I've got a big socket set with imperial sockets that don't get used for anything else so maybe I’ll try that first! I have managed to get the lower ones out already, so can give the actual carrier a wack with a hammer too to free it up a little. Gonna soak them in plusgas a few days prior too!

Got 3 of the 4 off with my allen key bit on a 2ft long 1/2" ratchet after a soaking in plus gas. 1 of them is rounded off. Managed to break it loose slightly by giving the caliper carrier a fair old wack, but can't get any purchase on it, so the Irwins have been ordered and I can complete the job at the weekend.
