Default Damn brakes!

Hey all,

Just wondering what some of you do to keep your brakes stopping hard? I have twin discs either side of the centre diff and boy, no matter what I do in terms of set up and cleaning I cannot get the pads to bite. Its really starting to p#ss me off.
Thanks

what servo are you using. A weak servo and improper linkage setup will be the two problems your having. What chassis are you running?

Cool thanks. Sand paper and brakeclean worked well, but still not the best. I have the linkage set to give the most mechanical advantage. Its a tamiya3004 servo. Chassis is a Nitrage. Any ideas on a replacement servo? Brand, specs etc.

Cheers all

Your servo is too weak, Get something in the 90oz range. Futaba S3305 or similar would be fine. BTW I also believe the servo arm on your Tamiya servo have 25 splines, so a Futaba would brop right in without having to change arms.

+1 On your servo being weak I run a 3305 in my losi and it stops on a dime. If I am not mistake a 3305 is about $60 bucks spend the extra $20 and get you a Ace 1015 digital. linkage setup is also a source of throttle brake problems. Even once you get a better servo work on your linkage.

I would not use 250 grit sandpaper more like 1000 grit is best. 25o grit takes of to much per stroke. You want to sand it down the least amount possible to achieve the desired effect. You can always sand it a little more with 1000. You can never put back on what you've taken off.

I hear that! I had some 180 laying around... big mistake. Grabbed the 2nd hand pads I had and bought some 600. Much better! I just bought a cheap and nasty TowerPro 955 off E Bay, cheap enough to throw away if its crap. I'll look more into the Futuba 3305. Not having to make any mods is always good.

Thanks all

Couldn't be bothered waiting for the al cheapo E Bay servo to arrive so I went down and grabbed a Futaba 3010. Magic, I got smoke coming off the pads (after an aggressive tuning session) and she stops on a dime. Very happy, thanks for your help people.
