Rebuild a disc brake caliper??

While towing the CC23 home recently I noted a very hot wheel hub. We got home ok, and found that the problem was not the bearings but the disc brake caliper was dragging and caused the heating.

Ordered a replacement caliper and it's installed.

My question is: is it possible to rebuild the old caliper? The new caliper was about $100, but if I could rebuild the old unit economically, I might keep it around as a spare (I figure the other three calipers getting ready to do the same thing. Dang.)

Yes it is possible after you dis-assemble the piston and inspect
it and the bore, and see if replacement parts are needed.

This site saved me a fortune last year when I replaced power window regualtors on 2 vehicles.
Sorry not hijacking the topic, I am adding value
 
Calipers can be expensive. To rebuild one you need to remove the puck and inspect the bore. Use compressed air to force the puck out. Most of the time the culprit is corrosion from water and residue that sits at the bottom of the bore.
The seal is tough to replace unless you have something to use to press it in.
Have fun.
 
Casey...Sure they are really easy to rebuild...and when you buy the rebuild kit you will look in the box and think you were robbed.... there is only a square cut seal (looks like a O ring) and the rubber dust cover...thats it... they come is fairly standard sizes so you could buy one at your local discount auto parts.... the piston is nickle coated and if it is not perfect they are also real inexpensive to replace... Usually any brake shop will rebuild a caliper for about $15 plus parts...but if you like..I will be happy to rebuild it for you for free.. (plus parts)..

With calipers that go underwater, will you have corrosion that is too deep to just polish up? Let's assume the seal is still intact.

Joel,

Thanks for the offer. I'll keep that in mind.

Maybe I'll try it myself, and after I get it screwed-up I'll just sent you a box
of parts!

We're currently in AZ and the caliper is in FL; so maybe when I get back to FL I'll tackle it.

Rarely a problem with corrosion....not at all like a wheel cylinder...a caliper piston only touches the inner edge of the square cut seal...and the dust boot... so the bore of the caliper can have all the pits it wants...just as long as they have not eroded the contact area of the square cut seal...I polish out the bore of the cylinder...clean the piston with brake parts cleaner...lube with brake fluid and it goes back together...really quite easy once you see someone do it...
The caliper piston is nickle plated and if it shows any rust it is very inexpensive to replace...

Casey the same thing happened to us coming up from Naples ,fl. to Lake tellico ,tn 800 miles we had a caliper freeze up on us

I called continental trailers and they sent a new caliper and pads so hopefully I will get it fixed this week . coming up from fl we got 10-11 mpg towing 5000lb with a 07 toyota sequoia with 4.7 v-8

I wonder what mileage you guys get towing c-22 and c25s towing with v-8's I thought I might get a little more ?
