Baer Brakes 4302418B Details

The Extreme+ system comes with the 1-piece Monoblock 6-piston, 6S caliper mounted to a 14", 2 piece slot, drill, zinc plated rotor. The 6S caliper is fully machined in Phoenix, AZ from a US sourced 2618 Aluminum forging, includes stainless steel pistons and abutments, D.O.T. compliant dust and weather seals and uses the popular D1247 pad type. Rotors are pre-assembled with NAS high grade stainless hardware. Baer’s unique backing plate not only acts as a caliper mount, but also houses a modern 1-piece park brake shoe assembly. Stainless braided hoses and hardware are also included. The 14” Extreme+ fits most 18” or larger wheels.

  • ** Because of the abundance of wheel companies and styles, it is impossible for Baer to guarantee fit of their brake systems into a specific wheel style and/or manufacturer. To verify fitment, we recommend using the template specific to the system you are interested in and compare it to the wheel of choice.**

    Formed as Baer, Inc. (Baer Brake Systems) in 1994, founder Hal Baer established the company from a racing background in the Corvette and World Challenge Series by identifying a gap in offerings for his own race cars. By using popular (at the time) PBR and Alcon calipers, he adapted and built complete systems (hose and fittings, etc.) for many popular domestic muscle cars.

    Today, in their 70,000sq ft facility in Phoenix, Arizona, Baer Brakes continues to be a leader in the performance brake industry by focusing on engineering design and innovative technology to deliver the most complete and detail-oriented brake solutions to their customers.

    Through their early relationships with high-profile OE prototype manufacturers and builders (such as Chrysler, General Motors, Roush, Shelby, Foose, Mark Steilow, Big Red, etc.), Baer became known as the premier domestic brake company which would later translate to being the face of the 'Pro-Touring' market segment. In the early 2000’s, Baer produced their first in-house caliper, the forged Monoblock 6S, which was soon followed by the extruded and machined 2-pc, 6P caliper. By doing this, it greatly reduced Baer's outside caliper dependencies and allowed them to focus even more on developing and manufacturing other components as well and transition from a systems integrator to full brake system builder. Baer Brakes was the official brake of the Overhaulin' TV show and in 2007, Baer was recognized by Hot Rod Magazine as "One of Twenty Companies that Changed the World and today they remain the brake system of choice for many top builders such as Roadster Shop, Ring Brothers, Goolsby Customs, etc., just to name a few. Bear’s success caught the attention of Holley Performance Brands and in 2021, Baer was acquired by them, solidifying Baer’s continued growth as an innovative leader in their space.
