better brakes needed

[JAG Motosports]

Have a lonestar frame with lonestar a arms and 400 ex spindles and calipers.... need more stopping power ... what are some other options

[motochamp250]

almost positive that YFZ450 calipers bolt directly up in place of the 400ex calipers and should be a significant improvement...

[bay citysteve]

use a bigger master cylinder !!

[gtilley45]

YFZ calipers will fit the 400EX spindles with no modification. That's what I have on my Walsh YZ.

[deathman53]

you could also get a set of 250r calipers w/ 400ex adapters. The yfz calipers are probably cheaper to get.

[gtilley45]

YFZ calipers are WAY cheaper than 250R calipers, or all the ones I could find anyway. I bought the YFZ calipers, lines, and master cylinder for $60. I'm running a TRX450R master cylinder, braided lines, and YFZ calipers on 400EX spindles.

if you use a road bike master cylinder you'll be able to stop with one finger , i'm tellin ya .. try it if you want good front brakes . leave the calipers alone ..

Thanks for the info

yea , something like that should work great for ya .. road bike ones have a bigger piston and push more fluid and make more presure witch brake better .. i have a single piston calipers on my quad and if i squezze them real hard they will lock rite up .. hope this helps ..

[gtilley45]

I THINK all the front YFZ calipers are the same. Just to be clear...the older steel framed, carburated YFZ. Not the newer YFZ-R.

this is interesting, if you do this give a report..........yeah the yfz brakes do bolt up and make a huge difference over the 400ex brakes

[JAG Motosports]

Thanks for everyones help... i'll let ya know which way I go and how it works

Ken we are running 2007 yfz calipers on the front of our blaster with the regular blaster master cylinder and they will lock the front up with no problem. Not to mention they are aluminum also. We did run the complete dual brake line system all the way to the master cylinder though instead of the t-line setup.

[JAG Motosports]

the blaster calipers and 400 are close to if not the same...I know they take the same pads... thanks for the info

[greenmachine70]

I just realized I wasnt clear on the last post. We are actually running full YFZ front end, caliper, rotor and spindles.

[HondaPohl]

I run drum brakes up front. Stop on a dime. LOL.

[jigg14]

I've got a set of YFZ calipers if you want some. Shoot me a PM if you're interested.
