Overview
Baer’s 4302268FR Pro Plus 13.0 inch disc brake kit comes in Fire Red and targets rear ends with a GM small pattern 10/12 bolt bearing-on-axle flange and 5×4.75 and 5×5.00 wheel bolt patterns. A 6-piston, 6P caliper clamps a 13 inch vented, slotted and drilled 2-piece rotor with a billet aluminum hat.
Rotors arrive assembled with NAS high grade stainless hardware. Baer’s backing plate mounts the caliper and includes a 1-piece park brake shoe assembly. The system fits wheels 17 inch or larger, and the minimum wheel diameter is 17.0 inch. Braided hoses and hardware are included with the kit, and the caliper is manufactured in Phoenix, Az.
Key features
- Staggered pistons help minimize uneven pad wear
- Stainless steel pistons with abutments and noise suppression clips
- Dual dust/weather and pressure seals
- Powder coated finish on a CNC machined aluminum caliper
- Slotted, drilled, zinc-plated 2-piece rotor
- Brake hose DOT approved
Keeping the system in shape
The dual seals on the caliper keep dust, water and pressure where they belong, but seals still age. Pull the caliper during pad changes and look at the piston boots, slide pins and seal lips for cracks or corrosion. Clean and lubricate the slide pins with the correct caliper grease so the caliper floats freely and the pads release evenly.
Fluid is the other half of the picture. Brake fluid pulls in moisture from the air, which lowers its boiling point and can make the pedal feel soft during repeated hard stops. Flush the fluid on the schedule for your vehicle and use a type approved for your braking system.
- Inspect piston boots and slide pins during pad changes
- Clean slide pins and apply the correct caliper grease
- Flush brake fluid on your vehicle’s schedule
- Watch for a soft pedal or fluid around the caliper

Vehicle fitment
The kit matches the GM small pattern 10/12 bolt bearing-on-axle rear flange used by Buick, Olds and Pontiac and the 5×4.75/5×5.00 wheel bolt pattern. Vehicle fit follows from those two items, so confirm both for your axle before ordering.
Rear ends with other flanges, bolt patterns or wheel sizes fall outside this kit’s stated match. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Confirm wheel clearance with Baer’s Q110H template prior to mounting the 13 inch rotor and 6P caliper. The rotor is already assembled with stainless hardware, and the park brake shoe assembly sits inside the backing plate. Park brake cables are not part of the kit, so arrange them separately if your setup needs them. A professional brake installer is the safest route.
What’s included
The kit includes the 6P caliper, the 13 inch 2-piece rotor with billet aluminum hat and stainless hardware, the Baer backing plate with its 1-piece park brake shoe assembly, and braided hoses with hardware.
Not included: park brake cables.
