Upgrade your classic GM vehicle with the Baer Brakes 4301432R 11-inch SS4+ front brake kit. Designed for 1964-1972 GM A-Body, 1967-1969 F-Body, and 1964-1974 X-Body cars with original-equipment spindles, this system combines compact packaging with four-piston stopping performance for vehicles using 15-inch wheels. It also fits select DSE, Heidt's, Fatman, Ridetech, L&H, and Speedway Motors G-Comp drop spindles. The kit increases track width by 0.200 inch per side when installed on original drum spindles.
The system includes Baer's S4 four-piston caliper, a two-piece slotted and drilled zinc-plated rotor, billet aluminum hubs, premium bearings packed with Redline synthetic grease, billet dust caps, mounting brackets, stainless braided brake hoses, and installation hardware. The calipers use DR1 or HB100 pad types and feature D.O.T.-compliant dust and weather seals for dependable protection against contamination. Rotors are pre-assembled with NAS-grade stainless hardware for convenient installation and long-term durability.
Manufactured with CNC-machined, U.S.-sourced forged or billet aluminum components, the SS4+ kit delivers a strong and refined braking solution for street-driven and performance-oriented classic cars. Hard-anodized aluminum pistons, stainless steel abutments, noise-suppression clips, pressure seals, and a powder-coated finish support reliable operation and reduced brake noise. The two-piece S4 caliper is manufactured in Phoenix, Arizona. Because wheel designs vary by manufacturer and style, Baer recommends comparing the system-specific fitment template with the intended wheel before purchase.
