All you need is to keep the pads apart. If the pen spring does not have enough pressure it can be stretch out to make it stronger. It's better to stretch the pen spring a little than to cut it longer.Did the pen mod also on baja 2. however....
found sometimes a pen spring may not be strong enough to push the pads back (obviously depends on the springs) - particularly if the brakes are new and the cam sticks (and stock bushes are used instead of bearings eg. as on some of the upgraded brake kits). It may loosen up but have not run this baja as yet.
Anyway, the spring which has been removed from the back of the linkage and replaced with fuel tube does the job perfect. It is a strong spring, strong enough to even force the cam back if it does sticks. The movement has a nice feel to it too.
Ideal perhaps if youre running with an upgraded throttle servo - maybe fine even with stock.

I'm going to look into the original spring off the brakes like you guys are talking about. It just seems like it has too big of a diameter. ...S
I would have to agree and disagreeI DO NOT recommend using the original spring being replaced by the fuel tube. The brake spring is to big in diameter and more importantly it is too stiff. The pen spring is much softer and it has the right spacing between coils.
As you can see, the spring has been cut into about thirds. If you cut it a little short just stretch the spring a little. All you want it to do is keep the pads apart, it's NOT a return spring.
And one last shot of the brake system and my servo of choice.
Yes sir, please check the pen spring.i have been using the original spring on mine for a while, maybe your right seeing as i seem to get little to no braking [even on a good servo]. i will try the pen spring and see if it makes a difference or not
