Slide pin keeps sticking

[HoosierJeeper]

Having issues on my 05 liberty with one of the slide pins sticking on the passenger front caliper. I can get it moving freely, seems good for a month or so and then gradually starts sticking again. I've tried sil glyde and some blue synthetic grease, along with moly caliper grease and none of them have worked. Any ideas?

Thanks!

The rubber in the bracket it rides in is swollen or the bracket itself corroded pushing inwards on the rubber.

You can either change out the bracket or drill that rubber out of there if you don't mind a little noise.

The pin when wiped clean should be pristine looking. Did you sand or steel wool or wire brush it? If its not pristine looking after cleaning it then replace the pin.

I probably could do a better job of cleaning it. I don't think there's rubber inside the hole, none on the pins that's for sure. When I buy pins for it, the box comes with rubber and non rubber ones and I've just used the non rubber ones.

You need to confirm that there's no rubber bushing stuck in the bracket. Typically only one of the two pins will have the bushing so compare the other front caliper not just the other pin on that same caliper.

Will do. If memory serves me right, I've never used ones with rubber on it. But I will check.

Be careful how you clean it. Anything beyond a brass brush is too aggressive and will remove the plating and may cause rust.

OEM replacements are typically about $10.

Ordered a new caliper/bracket from Advance (that's where the current bracket is from, I just get the new bracket and return the old bracket with the new caliper). Planning on doing the same thing again, since I'd rather keep my functional OEM caliper. Will it include new slide pins? What should I grease them with?

When I had this problem on a motorcycle (1980 Yamaha), despite new rubber and wire brushing the caliper holes I was able to solve it, virtually 100%, with a version of Krytox (Finish Line Xtreme Fluoro). I had previously tried both Syl-glide and Motorcraft silicone grease.
