Wilwood 140-10953 Rear Big Brake Parking Brake Kit Rotor - AERO4 14.00

The Wilwood 140-10953 AERO4 Rear Big Brake Parking Brake Kit is a bolt-on rear disc brake upgrade engineered for Oldsmobile and Pontiac axles with a 2.810" axle offset. Designed to complement front big brake upgrades on custom, show, and high-performance street machines, this kit delivers serious stopping power with a clean, high-tech appearance.

At the heart of this kit are forged AERO4 four-piston radial mount calipers paired with oversized 14.00" two-piece vented rotors. High-friction BP-10 compound brake pads round out the braking package, delivering optimized and balanced braking force that is matched to OE master cylinder output and ABS system requirements.

A standout feature of this kit is the integrated internal drum-style parking brake hidden neatly within the rotor hat, providing superior static holding power with a clean, uncluttered installation. No external parking brake hardware is visible, keeping the look refined under custom and aftermarket wheels.

Key Features:

• Forged AERO4 four-piston radial mount calipers — available in black or red finish
• 14.00" diameter x 1.100" wide two-piece vented rotors with internal drum-style parking brake
• High-friction BP-10 compound brake pads for optimized braking performance

This kit is an ideal upgrade for builders seeking maximum rear braking performance on classic muscle car platforms. The AERO4's radial mount design maximizes braking capacity within the confines of custom and race-offset wheels, while optional caliper finishes and rotor configurations allow full personalization to match any build aesthetic.
