Brake feel and bleeding..
« on: July 26, 2008, 06:43:24 PM »
So I have now had the Katana for one week.  When picking it up JB said the brakes were kind of mushy and didn't provide alot of feedback.  I would agree.  On the furthest lever setting the front brakes engage about halfway through the range.  I would like there to be less play in there, as well as have the brake engagement feel a bit firmer.  I tried bleeding them but there wasn't much air in the lines anyway.  Any other ways of adjusting this?

There is no way of adjusting it, BUT you should check and make sure the calipers slide freely on the pins. If the pins are frozen it will require the caliper pistons to travel farther to reach the rotors, hence the long lever travel. It's worth a look. You may have to pull the calipers off the forks to check and make they're sliding but it could be the answer to your problem.

I ended up just completely flushing the front with new fluid.  Still have some play, but the brakes do feel firmer now when engaged.

The calipers moved fine on the pins? That just could be the way it is. You may benefit from some good steel braided lines if thats not whats on there already.

Yes they seemed to move fine - not seized up.  I've been looking at steel lines lately, just not sure if it's worth it or not.

A lot of that spongey feel is the rubber lines buldging under pressure. The steel braided prevents that, all the power goes to the pistons and not swelling rubber lines. If it's something that bothers you then i'd upgrade at some point.

You COULD have air caught up in the master cylinder if you didn't vacuum bleed it but I sorta doubt it.

if you feel like spending some dolo i've heard steel braided lines are supposed to help with this.

I'll probably order a set of Galfers soon, along with some new tires.

galfer rotors and steel grake lines are a great upgrade,  and many bikes have multi piston front calipers (no pins).   the problem could simply be age, brake lines should be replaced if they look buldged or dry rotted at all.  front brakes on a motorcycle should not be taken for granted at all....
