Caliper tear down

[OB1]

Maybe some of the powder coating guys can help, but i need a description of what needs to be torn down on the calipers to get them prepped for PC'ing. Pics are always a plus. I've got some I was playing with but I don't know If I have everything off yet.

Oh geez :crazy:. I shouldn't be telling you how to do this really....... I don't have you on my list for powder coating .


Front Calipers:
-blow pistons out
-carefully remove dust boot
-remove o-ring inside caliper
-remove both rubber glide pin sleeves
-unbolt glide pins from bracket(torx bit)
-remove bleeder
-remove caliper spring


Rear Calipers
-remove metal pin with cotter
-remove glide pin (torx bit)
-remove plastic dust cap from torx screw
-remove plastic shield from grease boot
-remove bleeder
-remove P-brake return spring
-cut and remove zip tie
-remove rubber grease boot(back of caliper)
-remove pad spring
-twist out piston counter clockwise
-press/pry out rubber bushing with metal rings off both ends of the caliper body glide pin tunnel
-press/pry out rubber dust boot with metal ring (you can not get replacement parts for these, so don't damage them)
-remove o-ring inside caliper

I SUGGEST LEAVING THE NEXT STEPS ALONE IF YOU DO NOT KNOW HOW TO PUT THEM BACK TOGETHER!
-pull C clip from non-hooked end of ebrake lever
-put rag over caliper and pull ebrake lever out
-pull ebrake/piston shaft out of caliper body
-look for ebrake lever wedge and spring and keep them (the towel will catch the spring and wedge)



They can coat the rear caliper body with the ebrake lever still attached just have them mask off the lever and everything the rubber grease boot covered. It is not good for the o-ring on the ebrake/piston shaft if you do leave the lever assembled. You will have a hell of a time putting it back together without damaging the powder coat if you take the lever out. Good luck - Don't ask me how to put them back together either. This is all I can/will help you with. It becomes a liability if I go any further.

May i suggest also new boots,o-rings,seals etc on reassembly. Nothing like pretty new PC'd parts and then a torn seal/o-ring leak ruins the PCing.

Some boots you can't get, some are very expensive and no one wants to front the $ for getting all new seals/boots..... I can breakdown, coat, rebuild with old seals, and return them in better working condition than they are recieved 99.8% of the time. Most calipers just need a good cleaning to work properly, not a whole lot to go wrong with them really.


I patch boots with high temp black RTV. It is better than leaving a ripped boot ripped. It is the best I can do for the $ I don't make on caliper powder coating.

Anything special to taking the Baer calipers apart? Mine have yet to have been used, but I want to tear them down to powder coat them.

I just went ahead and took them apart. Nothing to it, just double the fun on each one
