look what i found when i spread the caliper.....it`s garbage or what? any advice?

[Black_peter]

Hmmm hard to tell. It isn't pretty..
However a member went to order a kit from the dealer and I think the price of the seal kit with pistons was pretty cheap, $30?? Worth looking into

Great thread. Thanks for putting it up.

I didn't see anyone post this link but I saw a few question about read calipers, Looks like this site would have the proper kit. http://www.crc2onlinecatalog.com/cal...build_kits.htm

How do you put the piston back in without cracking the caliper? I was bleeding my brakes and noticed that they were locking up. After examining the caliper that i thought was the culprit, i hit the brake lever a few times and it popped out along with a seal. How do i fix this?

Great job !

I could not pull the piston out with pliers. 100 psi air wouldn't do it either. What worked was 1500 psi air from a scuba tank
Just be sure to wrap a rag around the caliper to catch the pistons when they fly out!
It's probably best to push the pistons out as far as possible by pumping the brake before disconnecting the caliper - you'll waste a few cents of fluid but if you don't have 1500 psi air it may be the only way.

Yep, and that one was destine for a rebuild if it was that hard to get out! Normally they shoot out rather easy.

i am doing a rebuild not new to doing this done it on many bikes but the piston blocks on my gsx750f are seized into the pistons.
i have cracked open the caliper to do the rebuild but was wondering i could dremmel a slot in the piston blocks to try and budge them but
before i do i had a look to see if i can buy new ones from my supplier
they sell rebuild kits and pistons not the piston blocks.
are these 100% necessary are they there to stop vibration or hold the pistons there.

any advice of ideas to get the piston blocks out without dremmeling them.

Perhaps I' reading your question wrong but have you tried compressed air in increasing amounts? Some get really stuck in there hard due to buildups.

[gypsypunk]

have you tried compressed air


yeah i tried footpumping them out didnt work lol
so off to the garage to try the compressor.

If your going to rebuild them anyways, do you have access to a carb dip that would dissolve the deposits and rubber in there now? Berryman's carb dip available here would do that, and I would just soak the caliper in there for a bit, like a full day. By the time it's done, the gunk holding it and the rubber boots too should be basically gone and allow for very free movement of the pistons at that point.
