Overview
The Baer Brakes 4301542S is a silver Pro+ front disc brake kit with a 13-inch rotor, built for 4WD 1971–1987 Chevrolet and GMC Blazer, K5, K10 and Jimmy trucks. Baer labels it a Pro+ front kit for the GM truck Blazer K5, and it is intended for trucks with an original-equipment front axle and factory disc brakes.
The rotor is 13 inches across and Baer sets the minimum wheel at 17 inches, so the kit suits owners running larger rims on a four-wheel-drive truck. The six-piston caliper is powder coated in silver and uses stainless steel pistons, abutments and noise suppression clips.
