Any one else seem to go through rear brake pads a little too often on their 400ex? I have replaced the rear pads on both of my 400's 4 times each in a year and a half. Does anyone have any suggestions on a better quality brake pad than Braking, Ebc, or stock. I have tried all of these brands but not one seems to last very long.
And yes, I use anti-seize every time on the pins so they slide very easily. Thank you for any help you may have.

I just got my 400ex so not much help there but on my 250r i used dunlopad brakes (the heavy duty ones not sure of the name) and had good luck with them. On the same topic is there another prob causing your premature brake wear??? I would suggest checking the freeplay on your rear brake lever (can't tell you how though) Also, take the bike for a ride and then check to see if the brake is hanging up (feel more drag then usual when the rear axle is turned). The master cyl may not be allowing the fluid to return due to plugged ports, etc or the piston may be sticking in the bore of the caliper. Try flushing the brake fluid also if it appears contaminated or has not been changed in awhile. Just some ideas I hope they help

Try EBC kevlar pad, these work great and last a long time too. There's only about $20, good deal.

Also make shure your rear brake lever isn't siezing up on the pivot.

I'll have to double check on the year, but either the 2000 or 2001 400exs and ranchers are on a recall for their brakes. Only specific vin # atvs though, if you didn't already hear about this info I can send the exact specifics to you and see if it applies.

the recall would not wear out pads...

the recall was for both pads being installed on one side of the rear brake disk (maybe fronts too). so if you did have this problem, and already changed your brake pads, then obviously you would have installed them correctly.

i buy the EBC pads that are all black, and they seemed to last for like 1/2 a year, i went through 2 pads last year.

I've been using Magnum pads. They are lasting about twice as long as the ebc pads. If you ride in any mud at all you don't want kevlar,mine lasted 30 minutes.

ONEBAD440, Where do you get Magnum brake pads? I mostly ride on trails that are either muddy or packed snow. I also recently learned of solid rear rotors without any holes. Anybody tried those for mud riding? Thanks.

If you ride mud a solid rotor is the way to go. Polaris is noted for eating brake pads I went to a solid rear rotor and EBC hd pads and I have double the life. The holes hold all the grit and wear the pads & rotor quickly. As far as cooling goes I`m not racing or long steep down hills to heat them up, besides if the holes are filled with mud how much cooling do they offer? HTH
