Brake Bleeding

The upgraded Big Brake Kit actually feels pretty darned good to me. It firms up the feel on the lever and makes it a two finger operation. It is an improvement over the stock broke rotor with the sintered pad. Just make sure to really, really clean the brake rotor well with carb cleaner (or other solvent) before mounting. That was my problem - I failed to clean it well and was not sure why it wasn't performing better. I cleaned it very well with solvent and then bed in the pads. Works great now and I get plenty of nose dive when applying a firm grip on the brake lever.

According to the specs and pictures the front line is SS. That means that it is a rubber hose wrapped in SS mesh. That reduces the bulging of the hose. The hose can still bulge if the mesh is not tight enough. It might be benificial to check the hose while aplying the brake to see if it bulges.

Edit-teflon is usually used as the inner core rather that rubber. I would still check the line for any movement while braking to eliminate that variable.

All good thoughts and input!

I may pick up a Goodridge brake line next time I'm running errands in Sac. I ran them on my old Harley's front disks and they worked great. Not as costly as one may think either.

I do have a new master cylinder (and clutch lever assy) coming....if it ever arrives. I'm curious to see if (what's supposed to be) a larger bore may also help.

The curious part is the front rotor appears more than large enough to dissipate enough inertia and heat and the pads/caliper should be more than adequate for stopping a 250, even a fairly weighty one. It's not like we're trying to stop a fatty KLR here or something like that.

In all honesty, I don't ride near as aggressively as I once did so under regular riding, it's ok...but a front brake is pretty dang important when one really needs it to perform.
