sorting the Brake on an EB4 S2 Pro is quite simple, no need to alter the position of the actuator arm collars (located on the rod connected to the servo) or anything else.
With my S2 Pro, i was advised, and have, screwed in the allen bolts retaining the pads by 2 full turns. On the other hand, your situation may only require a small adjustment.
This method (above) is the EASIEST and FASTEST way of setting the brake up, it also removes the possibility of messing up the setting of the actuator arm.
With my buggy, i can run it at full speed and confidently stop the buggy inside 2-4 meters dependant on terrain, the fitment of a SECOND brake (to the rearward end of the center diff [RECOMMENDED UPGRADE !!]) would increase braking ability many times over.
The recommended setting for braking on a two disc arrangement is 60% front + 40% rear, although you can set this to your own needs.
One final thing, and this is my own personal advice here, is to buy and fit a "Super Torque" servo to the throttle/brake in place of the original standard one. The steering servo on the other hand is a super torque one AS STANDARD. That does beg the question of why they didnt fit one to the throttle/brake as standard. Only time will tell i guess.
Hope this helps out.
Any Thunder Tiger EB3 or EB4 S2 Pro questions, just ask.
