Soggy brakes - SV650.org

Nothing to do with falling off, but could do with some advice on brakes. Bike is 1999, put Goodridge hoses on in 2002 (lines split at m/cyl), just put in SBS dual carbon pads. Stripped calipers and used new seals last summer. System flushed and bled, no air (sure of this). Brake performance is okay but not great, and too much lever travel - as you roll the bike you have to pull the lever a bit before you hear the pads scraping, then a bit more and it starts stopping, but still feels a bit soft. A few years ago the brakes were a lot better. Do Goodridge hoses need replacing after a few years? Thought that was only the case with rubber ones. They look fine, no damage or squashed bits. I think the pistons are sucking back into the calipers too far - how come this never used to happen? It's cooking my head, I can usually fix these things!

Ahh ... the glory of sliding callipers

Sounds like sloppy callipers to me, this happens when they wear, try packing the sliding bits with grease to take up a bit of the slop.

I have found that SV calipers deteriorate, while you can rebuild them, rebult calipers do not feel the same as new ones,

But why? My mate's 1998 GSXR600 does the same thing but I can't figure that out either (4-piston opposed).

due to metal fatigue & erosion

New pads can feel soggy until they bed in - it feels as if you are having to flex them to get full contact with the disk
