It's not hard at all. Unbolt the caliper, unbolt the brake line, bolt the brake line back up to the new caliper and then bolt the caliper back on. Make sure to apply lube to the slide pins too and then bleed that brake. Seriosuly the worst thing about it is the rust & corosion on it. Let us know hot the replacement caliper works out for you... I think OEM ones are around $300!
I'm NOT a big fan of Advance Auto parts...so just be warned....hopefully it'll be fine.
If it's the same setup as my 05.......I found it easier to disconnect the brake line first....That way there's little chance of crimping the line. This is a solid line as opposed to many manufacturers who use a brake hose. If need be...spray a little PB Blaster on the brake like connector and the bleeding screw.
Did the caliper come preloaded with the pads?? If not...I found it easier to put the new pads (I'm assuming you're putting new pads in) in the Caliper first then put the caliper on the truck.
after i washed the wheels about 2 days ago, i drove about 100 miles and notice the drivers wheels was covered in brake dust...Having gone through this before (the other side last year...but i paid a clown to fix it...long story for another thread...he put the wrong caliper on the truck and gave it back to me...i realized it when i was rotating the tires six months later...) i wanted to see if the slide pins we frozze up...
i took the whole assembly apart to clean and lube...why i tried to push the pistons back in, they woud not budge...
