WillG. Posted August 6, 2011 Author Report Share Posted August 6, 2011 Today i bled the brakes, scubed the dirt off of the pads, cleaned the calipers and the pins, and scuffed the rotors with a non dirrectional finish. They still perform the same as before. Guess ill check into the yfz calipers. Quote Link to comment Share on other sites More sharing options...
dirtydownunder Posted August 6, 2011 Report Share Posted August 6, 2011 did you bleed it from the highest point ? the caliper is the lowest. if you can get a 450 setup for cheap, run with that. Quote Link to comment Share on other sites More sharing options...
WillG. Posted August 6, 2011 Author Report Share Posted August 6, 2011 Yes, i bled them from the caliper. I figured it would work like a car. Ill look at it again and see where else to bleed it from. Im going to head out and start riding around sun up to get a few hours of riding before the heat gets too bad. Hopefully it'll perform ok for time being. But the lever seems a lil spongy and i definately want to get it improved. Ill keep an eye out for a good priced 450 upgrade. Quote Link to comment Share on other sites More sharing options...
bigblockbanshee Posted August 6, 2011 Report Share Posted August 6, 2011 (edited) It's a simple process of elimination. If you've got the right amount of fresh fluid in with no air, the pads are good, the calipers are free, and the master cylinder is good, the only thing left are the lines/hoses. Sounds like you've got everything else covered so do you have stock rubber ones on now? I've not looked into the 450 calipers but I've got a 450 master cylinder for the front with Speedline'z braided lines front and rear on mine. I couldn't ask for better brakes. All it takes is a twitch of the lever and she grinds to a stop with ease. I've got maybe an inch of travel at the lever and I can't squeeze it any further. You'll have to weigh out the costs but I think my front lines were something like $65-70 shipped. Well worth every penny IMO.

dirtydownunder Posted August 6, 2011 Report Share Posted August 6, 2011 it is the same as a car, some car's brake systems if you run them dry, you have to bleed the trapped air around the lines. pump the lever, hold the leaver down, crack the pipe slowly, some air and brake fluid will come out, tighten the pipe/ bolt up and release the lever, do that till there is no air.

klever209 Posted August 6, 2011 Report Share Posted August 6, 2011 At the very least, you should do a good bleed down, after getting new hoses. My stock brakes work fine. I could never compare them to my CR250 but they will lock up and you will go over. The hoses get some of the spongy feeling out of the system with a shorter stroke, not that big but noticeable. Good luck. Quote Link to comment Share on other sites More sharing options...
WillG. Posted August 6, 2011 Author Report Share Posted August 6, 2011 Well I went out at dawn to get a few hours of riding in at Stoddard Wells before it got too hot. She ran pretty good. I noticed a bit of fuel coming from the left carb overflow tube earlier. Maybe the float got stuck since its pretty rough riding out there. I'll check it out later. I'll keep an eye out for a good deal on some yfz calipers. In the mean time I'll see about bleeding them again more thoroughly and go from there. Thank you everyone for all you input! :-) Quote Link to comment Share on other sites More sharing options...
