Traxxas 5417A Installation Manual

Dual Rear Brake Kit Installation
This kit is designed for the Traxxas Revo 3.3
and requires the installation of the center
differential (part #5414).
Note 1 - For TRX 2.5R-
equipped Revos, check the
rear transmission half for rear
brake mounting capability.
The rear transmission half (part #5391R) will be
necessary for the installation of the rear brake kit
(Fig. AA). The accessory left-side radio box cover
(part #5325X) can also be used to easily show where
the secondary brake linkage will need to pass
through (Fig. BB).

Note 2 - The rear brake
kit is designed for use
with the Revo 3.3 long
chassis. If you are
using a standard Revo
chassis, material will
need to be removed
for proper clearance
around the brake
components. Caution: Always use proper protective gear when cutting or
grinding aluminum. See illustration (Fig. CC) for material to be removed.
Install brake discs and
A
calipers
• With the transmission
removed, insert the
brake pin into the rear
output shaft (the hole
closest to the transmission case) (Fig. A).
Slide the brake hub over the output shaft
and key it onto the brake pin (Fig. B).
• Set one caliper on the rear transmission
case cover, and align the holes with the
two holes in the transmission case (Fig. C).
• Next, slide one brake disc over the brake
hub and up against the caliper. Follow the
brake disc with another caliper (Fig. D).
• Slide the second brake disc over the brake
hub, and follow the brake disc with the third
brake caliper.
• Make sure all caliper holes are aligned with
the holes on the transmission cover, and
then insert the two 3x10mm button head
machine screws through the calipers and
thread them into the transmission cover
(do not tighten) (Fig. E).
• Using your finger, apply even pressure to
the center of the outer brake caliper. While
holding steady pressure, drive each caliper
screw until it just stops at the caliper, and
then back off 1/2-turn, or until there is no
binding between the calipers and the brake
discs. The disc must be able to rotate freely
when the brake is not engaged (Fig. F).
Install brake lever
• Set the brake lever into the slots molded
into the transmission case, and then secure
the lever in the slots with the two 4x4mm
blue- anodized button head screws. Do not
overtighten these screws. The lever must
rotate freely with minimal play (Fig. G).
