caliper pins
I inspected my front brakes on my 2001 F250- I replaced rotors/calipers and pads last year- one of the caliper bolts was not moving as freely as the other so i cleaned it up and relubed- What effect does a stuck caliper pin have on the overall brake operation? I'm just trying to understand how it functions.... My rears were frozen altogether so I removed the bracket and got the pin out finally- did some damage to the pin and boot so I might just replace the whole thing to be safe.... Does a frozen pin cause the whole assembly to not work 100% or will it cause uneven wear?

The caliper slider pins are there to allow the caliper to slide. There is normally only hydraulic piston/s on one side of the caliper, so when the brakes are applied the piston pushes the pad on that side into contact with the rotor. Then, as more hydraulic pressure is applied the whole caliper slides across (on the slider pins) so that the opposite pad then comes into contact with the rotor. When this happens equal braking force is then applied to both sides of the rotor.
If you have sticking slider pins then often the caliper cannot return to release the braking force and you get a dragging brake. Also less braking force will be applied to the side of the rotor away from the piston so you get less braking and uneven pad wear.
Hope that makes sense.

Good info, on the theme of slide pins, does anyone have a good method to get them out when they are froze.. Trying PB Blaster now.. I see Guzzle mentions some heat, but rubber boots dont allow to much heat. Thanks for any info.
