Overview
Red 6S six-piston caliper paired with a 14 Inch two-piece slotted and drilled rotor makes up this Extreme+ front kit, part 4301524R, for the 1991 GMC Syclone and 1992–1993 GMC Typhoon. OE spindles and hubs are part of the package.
Baer Brakes assembles the hubs at its Phoenix, Az facility before the kit leaves, fitting the bearings and races and packing them with Redline synthetic grease. Installation therefore centers on bolting the finished assembly to the control arms instead of building hubs on site.
Key features
- Forged one-piece monoblock caliper with six pistons and a 6S designation
- Red powder coated caliper finish
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons intended to minimize uneven pad wear
- Dual seals guarding against dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with a billet aluminum hat
- Manufactured in Phoenix, Az from US sourced materials
Wheel clearance checks
Wheel clearance is the first thing to settle with a front brake kit of this size. A caliper and rotor set changes the space inside the wheel, so compare the intended wheel against the template before the tire goes on. Clearance also depends on offset, which affects how close the wheel sits to the caliper body. Lug nut choice affects clearance too.
Red finish is a cosmetic choice and does not change how the brake components work. Over time the paint can chip near the heat zone, so inspect it along with the pads and rotor during routine service. Keep the caliper clean of road grime so pad wear and fluid leaks are easier to spot. Fluid should be changed on a regular schedule.
- Look for scoring or heavy grooves on the rotor
- Check hoses for rubbing near the control arm

Vehicle fitment
This kit fits the 1991 GMC Syclone and the 1992–1993 GMC Typhoon, both as Extreme+ Front applications.
Other GMC pickups, Chevrolet trucks, and Syclone or Typhoon model years outside 1991–1993 are not covered by this part number. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the hubs arrive with bearings, races and grease already in place, the job is mainly bolting the assembly to the control arms. Lug nuts are not included, so select a set that suits the wheels you run. Baer does not guarantee fit with every wheel style, so test clearance with the N082P template against the intended wheel first.
What’s included
The package includes the 6S six-piston red caliper, the two-piece slotted and drilled front rotor with billet aluminum hat, and the OE spindles and hubs.
Not included: lug nuts.
