I am changing the brakes on a 2000 S Type. One of the pins/bolts is frozen in the caliper. I am assuming that it shouldn't frozen where it won't move at all. Anyway, does anyone have a trick to getting that pin out or should I buy a new caliper?

 

This is not rare at all, unfortunately. The pins must move freely to allow the caliper to slide back and forth and apply both the inner and outer pads. If the pin cannot be freed using a hammer or clamp then a new assembly might be required. Be sure to clean out all the old grease and corrosion and relubricate if it does come loose.

 

I have had luck freeing up the pins on some of the caliper frames. The frames cannot be had new from the dealer separately from the caliper (NSS).

Remove the frame from the vertical link, remove the rubber gaiter and spray some penetrating oil into the pin area. Try to gently twist it and spray, twist etc.

I have had to heat the frame with a torch and in several cases I had to drill a hole in the end of the frame to 'punch-out' the pin. You can seal the hole with some high temp silicone sealant.

You might have to find a used/salvaged part or at least replacement pins.

Use brake grease to prevent this from recurring.

You might want to remove ALL the pins and lube them before they seize!!!!
