Review GIBSON Brake Hardware Kit Premium Replacement Drum Brakes

Introducing the Gibson 3903-2 Brake Kit, an excellent upgrade for your classic or custom vehicle equipped with drum brakes. This high-performance brake kit is engineered to provide superior stopping power, improved pedal feel, and enhanced durability.

The heart of this brake kit is the set of four, 11.75-inch slotted and drilled rotors. These rotors are made from premium, high-carbon cast iron. Slotting and drilling are crucial cooling features that help reduce heat build-up during heavy braking, ensuring consistent performance. The drilled holes also provide improved brake pad bite and better water dissipation.

The kit includes a pair of high-carbon, 10.93-inch brake drums. These drums are precision machined for a perfect fit and feature vented surfaces to improve cooling efficiency. The drums are also finished with a durable, black powder coat to protect against the elements and resist corrosion.

The Gibson 3903-2 Brake Kit comes with a set of four, two-piece, directional, sintered iron brake shoes. These shoes are designed for optimal heat dissipation and longer pad life. The directional design provides improved stopping power and pedal feel, while the sintered iron compound ensures consistent performance in various driving conditions.

The kit includes a set of four brass-backed, steel brake shoes, which serve as a backup for the sintered shoes. The brass backing provides excellent heat conductivity and even wear, ensuring that your drum brakes perform consistently even when the sintered shoes wear out.

The Gibson 3903-2 Brake Kit also includes a set of four wheel cylinders. These cylinders are made from durable, high-quality materials and are specifically designed for drum brake systems. They feature a smooth, even brake shoe travel, ensuring consistent braking pressure and improved pedal feel.

The kit includes all necessary hardware, including stainless steel brake lines, brake line clips, and wheel studs. The stainless steel lines provide excellent resistance to corrosion and offer a crisp, responsive brake pedal feel.

In summary, the Gibson 3903-2 Brake Kit is an excellent choice for upgrading the drum brake system on your classic or custom vehicle. With its superior stopping power, improved pedal feel, and enhanced durability, this brake kit will provide you with the confidence and performance you need on the road.
