Title: Seized rear brake caliper
Post by: fazersteve on 05 February 2012, 06:04:48 pm

Hi all from a very cold Inverness,
 
Prior to taking my bike off for the winter I set about cleaning my brakes.Front both fine but the rear had a stuck piston.
 
Last week left the caliper with a mechanic friend to blow piston out with compressed air.The bad news is the piston is seized solid and will not move.
 
So do I have any other options apart from a second hand caliper.

i got mine out with mole grips, u have to be extremely careful though not to damange the piston, unless your buying new ones.

You could reconnect the calipers and bleed it,then clamping the good piston pump the piston out,hydraulic pressure should shift it

Haven/t suffered this problem yet,but apparently its a common Fazer problem.My old sumitomo's seized badly once but blew out okay,Sounds like a replacement caliper to me.Check this site as i think the Fazer 1000 is a straight swap,but a different type of caliper,therefore less prone to permanent seizure.If the piston is seized flush there is very little you can do.If you can catch a good edge Vise grips may release it,if you twist, but will damage the piston.

Hi,
 
Have tried clamping and using hydraulic pressure but just won't budge.

Are the caliper from the 1000 just a straight swap.

Someone with more knowledge than i have will answer,but i'm sure i read it somewhere.Problem is i've owned too many bikes over th years and my old brain can only hold a certain amount of data.The problem is just finding the right model ie Gen 1 FZ1 FZR!!!.

Yeah, they are a straight swap apart from having to slightly modify the caliper bracket.You just need to cut/file a small part of it away so the bolt holes line up. You'll need a caliper from a 2001-2005 FZ1.
