Hey guys. One of my rear caliper are sticking.. Not quite sure which one but I'll investigate tomorrow in more detail. This happened last year,close to 6 months ago and I serviced the rears with a seal kit for both calipers however I didn't renew the pistons. 
Question is I'm looking for two replacements possibly upgrades. 
There's two on flea Bay for 159 plus 90 on top of that which I'll get back when I get the old ones sent off. 
Is this the best deal I'm gonna  get or do you guys know better? 
Thanks 
George
