Front brake caliper piston change
Hey guys.
The brake pistons on my truck broke, and I could not find any caliper rebuild threads, most seem to just buy new calipers and change them out, but living in Iceland and parts being a bit expensive so I decided to rebuild the calipers and make my own thread .
Well the conditions were not the best....but they donīt call it ICE-land for nothing
Here are the broken pistons. I did not have the tools to pull out the old pistons so I had to use a hammer and chisel and brake the old pistons to pieces.
Just pry out the rubber that holds the piston.
Just remember the thin rubber seal.
Here are the new pistons with the rubber attached.
Using the old pad and brake caliper press or C-clamp to slowly press the new pistons in.
And there you have it...good as new
Then itīs just a matter of putting it back on the truck and bleeding out the brakes.
Hope some one finds this useful.

Dang, is it really that easy? Seems like an hours work! I bought new calipers as I felt the internals were gone causing them to seize. Spent over $300 on new calipers. Don't want to know how much new pistons were for you then! Pretty crazy how delicate the pistons are after a few years of use.

I got my stuff at O'Reilly down the street for $12. Most of it went really well but I had a lot of issues getting the outside dust seal to press all the way in. I cleaned up the caliper as it had rust and such on it. The first issue is that there was a bump in the casting which wouldn't allow the seal to pass over so I had to give it a bump with a dremel tool. Then to press it in the last 2 mm or so I ended up using a cast plumbing cap that I bought at Lowes and the same diameter with the c-clamp and it went right in. So far I'm loving my Powerslot 1 click rear kit.
