Overview
The Baer Brakes Pro Plus 13.0-inch rear brake kit in Fire Red, part number 4302344FR, is a rear disc system for axles with the GM small pattern 10/12 bolt flange, flush mount bearing and a 5×4.75/5×5.00 bolt circle. Confirm fit for your vehicle’s year, model and trim before ordering.
A Fire Red powder coat covers the CNC machined aluminum caliper body. Six pistons in a fixed 6P caliper clamp a vented 13.0-inch rear rotor. The rotor is two pieces: a slotted, drilled, zinc-plated ring on a billet aluminum hat. The backing plate carries the caliper and a one-piece park brake shoe assembly.
Key features
- Fire Red finish on a six-piston fixed caliper
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons work to minimize uneven pad wear
- Dual seals for dust, weather and pressure
- Two-piece zinc-plated, slotted and drilled rotor on a billet aluminum hat
- Integrated backing plate with park brake shoe assembly
- Pad type FMSI D0731
Axle and wheel checks
Rear kits of this type are matched to the axle before they are matched to the vehicle name. The backing plate carries the caliper and the park brake shoe assembly, so the flange, bearing and bolt pattern all need to line up before the kit goes on. A quick measurement of the flange and a look at the existing brake hardware will show whether the layout is the same.
Larger rotors on a rear axle can fill more of the wheel opening, so wheel clearance deserves attention before the tires are mounted. Fire Red calipers look the same on the outside as other finishes, but the internal fit depends on the backing plate. Plan on replacing the park brake cables if they show stretching or corrosion, since they are not part of this package.
- Measure the axle flange and bolt pattern before ordering
- Check wheel clearance around the larger rotor
- Plan for new park brake cables if the old ones are worn

Vehicle fitment
Fit is set by the axle rather than a named vehicle. The kit targets rear axles with the GM small pattern 10/12 bolt flange, flush mount bearing and 5×4.75/5×5.00 bolt pattern, and it suits wheels 17 inch or larger.
Compare the flange and bolt pattern with your axle, then confirm your vehicle’s year, model and trim before ordering.
Installation notes
Fit depends on the axle flange, because the backing plate doubles as the caliper mount and an axle with a different layout will not accept this kit. Park brake cables are not part of the package. Rear brake and park brake installs call for hands-on brake repair experience.
What’s included
Fire Red fixed 6P caliper, two-piece 13.0-inch rotors, a backing plate with one-piece park brake shoe assembly, and braided brake hoses with hardware.
Not included: Park brake cables.
