An apparatus and methods are provided for a braking system for a front portal drivetrain assembly to improve the mechanical strength and performance of vehicle drivetrains. The braking system includes a brake caliper coupled with a drivetrain and a brake disc coupled to a drive axle such that a periphery of the brake disc passes within the brake caliper. A front portal spindle assembly includes a pinion gear assembly and an output gear assembly that provide a gear reduction at a front wheel of the vehicle. Upon activation of the braking system, the brake caliper applies pressure to the brake disc to slow rotation of the drive axle while the gear reduction at the front wheel contributes to engine braking during deceleration of the vehicle. The gear reduction of the front portal spindle assembly facilitates reducing the size of the brake caliper, the brake disc, or a combination thereof.
