have a 99 150 w/ 4wheel discs..haveing a little trouble with the "sleeves" hanging up..(just did a brake job, turned rotors and removed and cleaned the sleeves) then had one rear caliper "dragging" and come to find out the sleeves are real tight..tried a little wheel bearing grease and that does not really help...it helps for a few minutes and then as you slide them back and forth they seem to tighten up????! looks like plastic material insde of those little rubber boots..are those replaceable? or buy the whole caliper..any ideas?? thanks

 

this is actually from a few days ago..found rust had built up under the rubber "boots" where the slides go thru..opened them up a little with a dremal..a little never seize inside the boot and its like new again..they move smoothly now..i should have looked at this before..

 

Also don't use axle grease. It will collect dirt and moisture. Use dielectric grease. It will not attract moisture.

 

I need to get a sleeve for my 99 f150 4x4 front discs. i have 17" rims and would like to know where i may be able to get those sleeves from?? Any help?
