Seized brake piston

[andy120t]

Good work...my advice was going to be to get a 'sprotor' (horrible word for a sprocket rotor!), then you wouldn't need the front brake. Or divert the build to be a speedway style bike and stick with a rear brake only!

Damn...good work getting that thing out. Can see now why it didn;t want to shift.

I had one stuck piston on my brakes that didn;t want to shift, but it was such a nice feeling when I finally got it to budge, and I could clean out the sludge, gunk and sludge that can build up in a brake caliper given enough time

Good work, they really do keep quite a grip in there with corrosion don't they.

Many of the current cars get similar affects on rear calipers with aluminium construction, no routine servicing (much advice now is to swap calipers when seized) and combined handbrake mechanism and they often get very tight with salt corrosion. They creak like an old galleon when pushed out with the assisted brake pressure on the car. Clean up fine though and reassemble with silicone grease to prevent corrosion, they work as good as new.

That seal groove will need to be very critically cleaned for the caliper to work well when rebuilding.

At least we can get seals for the bikes, most cars now you cant get kits.

Once again thanks for all the advice and comments. The pop when it finally came out was very satisfying, but it put up a hell of fight! 😀

Well done PX in finally getting the piston out - these victories along the way make it all worthwhile.

Cheers Ted - one giant step for man and all that! Front fork rebuild next whilst some parts go to the sandblaster. But still looking for bits that were missing 😀

You were lucky, when I bought my 400 I never noticed the bleed nipple was missing off the front brake, on strip down had to bite the bullet and get a new caliper as someone had filled the threaded part where the bleed nipple went with liquid metal. I tried to clear it all out but it was too far down into the fluid ways, how they bleed the brakes I have no idea. My first thoughts when I saw the missing nipple was, not a problem drill out the old one best I can, stud extractor to remove what was let, not a problem, recut the threads, how wrong I was.

Where do find his details Bryan? I'm sure I've seen a list of suppliers on here but cant remember how to navigate back to it again.

It's me age!
