Nighty Posted August 27, 2010 Report Share Posted August 27, 2010 Hey all, I mounted yfz450 brake calipers on the banshee, and made some pics for a small howto. The mod is easy to do, and the brake performance is much better compared to the stock single piston caliper. Single piston sucks Here goes: Gather your needed parts -dot4 brake fluid -yfz450 brake calipers, can be obtained for a fair price check ebay! -optional, the yfz450 master brake cylinder + lever. -a bike to work on. -a tiny hose to help you bleed the brakes. -doggy for mental support. -Bike to work on -needed parts -The reïnforcements Start by removing both front wheels. -First wheel removed Then remove the old brake calipers by removing the 2 bolts holding it and the brake fluid line.Some brake fluid may drip out of the hose, !be carefull! i hear its agressive stuff.When removing the old caliper you might have to bend the metal dust cover a little outward.Or dont be lazy and try to remove it, its held down with just 1 bolt as far as i know. -1ste caliper removed -The bend dust cover to allow removal. Since the yfz450 brake calipers are wider you need to modify the metal dust cover to fit the calipers.Like so: -bottem piece and -Top piece I took of a bit too much, this job can be done tighter, if you take the time to remove the metal dust cover and line out exactly where to cut. Here's the finished cover: -ready for new caliper. now you can install the yfz450 brake caliper, it should just slide on, the bolt patern matches. -installed caliper. With the caliper installed you can see the brake pads fit the brake disk allright. The complete width of the brake pads is perfectly used. However the complete width of the brake disk is not used, (angle of caliper could be better) In the picture you can see the brake pads are completly on the disk. The stock caliper/pads combination used a bit more surface area on the lower parts of the brake disk. -brakepad on disk. Now comes the crappy part. bleeding your brakes properly.I hear there are special brake bleed devices availeble which can help you get the air out of the system. i dont have that This job is best done with two people. Make sure the brake reservoir on your handle bar has plenty of oil and keep an eye on the reservoir during the brake bleeding. attach a shine trough hose on one of the brake calipers, the calipers have a special valve. The shine trough helps you see the oil and air come out. First stage: have someone to use the brake lever. have someone to open and close the bleed valve. -open bleed valve -squize the brake lever and hold it down. -close the bleed valve -release brake lever -repeat until you see oil comming into your shine trough hose. With oil in your tube its now no longer possible to suck in air trough the bleed valve when releasing the brake lever so now: -open the bleed valve -squize the brake lever You will see the oil level in the tube rize and possible some air bubbels comming up trough the hose. -slowly release the brake lever oil level will drop some -repeat until no more air comes out. -close valve Do same for your other brake caliper. -brake bleeding. after you have done this for both sides, you should have a firm brake pressure when using the front brake lever. You should never be able to squize the lever all up to the handlebar. You.. and i should checkout a clymer or other repair manual since that might have some great brake bleeding tips aswell. Take your bike for a spin and make sure your brakes function! you should now have a much better front brake control, beeing able to stop the front wheels with much less effort. The finished product. I did not replace my stock master cylinder. Maybe somebody here can tell me if the 450 master brake cilinder has more capacity then a stock 2006 banshee one? On my old 2000 banshee i did the same modification and changing the master brake cilinder was an improvement over the stock one. Feedback welcome and feel free to use this stuff to write a better howto. Regards, Ton 1 Quote Link to comment Share on other sites More sharing options...
Sands Posted August 27, 2010 Report Share Posted August 27, 2010 Nice DIY. I also fit the 450 caliper at the rear carrier. Quote Link to comment Share on other sites More sharing options...

Glenyboy Posted March 14, 2011 Report Share Posted March 14, 2011 This seems like a good and cheap mod! They really are quite cheap! What year are the calipers? Just I've read there's a couple of variants, and do they make much of a difference? Quote Link to comment Share on other sites More sharing options...
Banshee Chad Posted March 14, 2011 Report Share Posted March 14, 2011 Do the banshee ones not work well? I grab my lever and the fronts lock up.. Quote Link to comment Share on other sites More sharing options...
shanYE west Posted March 14, 2011 Report Share Posted March 14, 2011 Do the banshee ones not work well? I grab my lever and the fronts lock up.. same here... I've never had a problem with the front brake stopping power. Quote Link to comment Share on other sites More sharing options...
06specialedition Posted March 14, 2011 Report Share Posted March 14, 2011 Good write up! I would be interested to see how much these really do help over stock....I'm sure ALOT has to do with riding surface. I ride 100% sand, and if the sand is super soft I can pull my front brakes and have the tires lock up...but my bike will keep sliding (if coming down a really steep hill) Quote Link to comment Share on other sites More sharing options...
gotta_goatsfast Posted March 14, 2011 Report Share Posted March 14, 2011 It makes a difference in feel. When I swapped out last year I could lock the front up with one finger. Has better feedback and its smoother. Quote Link to comment Share on other sites More sharing options...
Burt Reynolds Posted March 14, 2011 Report Share Posted March 14, 2011 (edited) Stock brakes work ok,but switch back and forth between a yfz and a banshee and you will see the difference. I especially noticed a big improvement on long downhills,the yfz grabs harder with easier pull. In situations where you are going from high speeds to a stop you dont notice much because any old brake thats setup correctly will lock up. YFZ brakes are more effective through the whole range. One of the big parts of having performance brakes is that they will work well without locking up until you need them to. I would do the master though along with the calipers. Honda 450r brakes are even better,my bud has an 07 450r with braided lines and the front brakes are insanely good.

banshee jump Posted May 11, 2012 Report Share Posted May 11, 2012 nice description will try it out Quote Link to comment Share on other sites More sharing options...
Sandfrk33 Posted May 12, 2012 Report Share Posted May 12, 2012 Did mine a few years back. They really do make a nice difference. They almost feel like anti-lock brakes. You can still lock them up, but it slows down without doing it. Only thing I did different, was remove the brush guard completely. I'm in the sand with it, and it looks cleaner Quote Link to comment Share on other sites More sharing options...

Trick2stroke Posted May 15, 2012 Report Share Posted May 15, 2012 Not all year yfz calipers will work I am told...any truth to this? This is the first I've heard of this. I don't believe there were any changes to the calipers or spindles on any year YFZ. Quote Link to comment Share on other sites More sharing options...
