4 pot brakes reconditioned.

[cusco scooby wagon]

 ive just got another set of calipers to recondition.

 

 typical 4 pot sticking piston's one on each caliper,  nipple side on the bottom piston each set ive done always seems to have the same fault their either solid or only half working.

 

  i have taken photos of stripping the calipers down to their core units ready to be blasted, ported, painted and re-built using all new seals and or reconditioned parts

 

   new pad pins & spring clips,nipples,banjos and pistons if needed.

they do look well shot - amazing how bad some of these calipers are left to get

I'd say mine look that bad :( one of the next things I need to look at doing I think the calipers. But thanks for the pictures does show how bad they get.

have you thought of using a grease gun to get the pistons out - high pressure but no sudden expansion when they go, unlike air pressure avoids flying metal?

I was watching a video on youtube of a bloke doing the grease gun look's messy but fun :D

i used to use grease but it took ages to get the grease out of the passageways.

 the grease method was ok but messy and it doesn't matter what you use to get them out it still makes a bang and if your fingers are in the way it hurts i can tell you....

 

  so now ive converted a blow gun that i can screw into the banjo thread part of the caliper and inflate them so as pushing the pistons out most of the time this works fine but there is always one that's well and truly stuck and not for moving .

Always the case ;) Just like that last screw or bolt that has to be a real pain to undo it.
