Overview
The Baer Brakes 4302266GB is a Pro Plus 14.0 inch rear disc brake kit with a Grabber Blue caliper. It is built for GM small pattern 10/12 bolt bearing-on-axle rear ends with a 5×4.75/5×5.00 bolt pattern. Its six-piston fixed caliper clamps a 14 inch two-piece rotor that is vented, slotted, drilled and zinc plated, with a billet aluminum hat.
A single backing plate carries the caliper mount and houses a one-piece park brake shoe assembly, so the parking brake shares the rear unit. Stainless hardware comes installed on the pre-assembled rotors. Dust and weather seals and the D0731 pad type complete the design. The 14 inch Pro Plus suits wheels 18 inch or larger.
Key features
- Staggered pistons on the six-piston caliper aim to reduce uneven pad wear
- Stainless pistons paired with stainless abutments and noise clips
- Dual seals keep out dust and weather while resisting pressure
- Two-piece rotor, slotted and drilled, zinc plated, with a billet aluminum hat
- Components CNC machined from forged or billet aluminum sourced in the US
- Powder coated finish throughout
- Braided hoses come with matching hardware
Choosing wheels and rotor size
A 14 inch rotor sits inside the wheel, so inner clearance and spoke layout matter as much as diameter. Wheels with thick spokes or deep center pockets can contact the caliper body or the hat. Measure the caliper and rotor against the wheel before buying tires, and remember that tire width and offset also change clearance.
Larger rotors store more heat, which helps on long downhill runs but means pads must be bedded in properly. Stop gradually a few times before heavy braking, and let the rotors cool after the first hard session. Vented rotors need clear airflow, so mud packed into the vanes should be removed after off-road use.
- Match tire diameter to the brake clearance you measured
- Check lug seats and stud condition on every wheel mount
- Flush brake fluid at a regular interval during heavy use

Vehicle fitment
This Grabber Blue kit is built for rear axles with a GM small pattern 10/12 bolt flange and a 5×4.75/5×5.00 wheel bolt pattern. Compare those two dimensions on your axle with the specifications above.
Make sure the year, model and trim fit your vehicle before ordering. A rear end with a different flange or bolt pattern falls outside this kit’s design, so measure the axle before buying.
Installation notes
With pre-assembled rotors, the wheel is the step that needs the most care. Check the wheel against the Q110P template, because Baer does not promise fit across all wheel designs. A shop familiar with rear park brake hardware is the right choice for this kit.
What’s included
The package covers the six-piston Grabber Blue caliper, the 14 inch two-piece rotors with stainless hardware, the backing plate with its park brake shoe assembly, and braided hoses with matching hardware.
Not included: park brake cables.
