Overview
The Baer Brakes 4302341R is a red Extreme Plus 14.0 inch rear disc brake kit for GM small pattern 10/12 bolt axles with bearing on axle and flush mount bearing housing ends. A one-piece monoblock six-piston 6S caliper clamps a two-piece slotted, drilled rotor, and the kit lists 5×4.75/5×5.00 wheel bolt patterns.
The backing plate holds both the caliper mount and a one-piece park brake shoe assembly. The D1247 pad type fits this caliper, and the caliper body is machined from 2618 aluminum forging. The rotor thickness is 1.25.
Key features
- Red powder coated one-piece monoblock six-piston caliper
- Caliper body CNC machined from US sourced 2618 aluminum forging
- Stainless steel pistons paired with abutments and noise suppression clips
- Staggered piston layout that limits uneven pad wear
- Dual seals guard against dust, weather and pressure
- Slotted, drilled, zinc-plated two-piece rotor with billet aluminum hat
- Pre-assembled rotors fitted with NAS high grade stainless hardware
- D1247 pad type, with stainless steel hoses and hardware included
Keeping the rotors true
Rotor condition has a direct effect on how smoothly the brakes work. Heat from repeated stops can cause uneven wear, and an overheated rotor may develop a blue tint or hard spots. Measure the rotor thickness at several points around the face during each pad change. Uneven readings point to runout or pad transfer, and the rotor should be resurfaced or replaced when it falls below minimum.
The hub surface behind the rotor matters as well. Rust or debris between the rotor hat and hub can throw the rotor out of true, so clean both faces before mounting. Torque the wheel nuts evenly in a star pattern, then recheck them after the first drives. Keeping the stainless hardware clean makes later removal easier.
- Clean the hub face before mounting the rotor
- Torque lug nuts in a star pattern
- Check rotor runout with a dial indicator
- Replace pads when friction material is worn

Vehicle fitment
The rear axle flange is GM small pattern 10/12 bolt with a flush mount bearing, the wheel bolt pattern is 5×4.75/5×5.00, and the minimum wheel diameter is 18.0 inch. Those points define the match. Confirm your vehicle’s year, model and trim before ordering.
Axle pattern and wheel size alone do not establish which vehicle this covers. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotors arrive with stainless hardware already assembled. Compare the N110P template to the wheel you intend to use before mounting, as Baer does not guarantee fit to every wheel style. Park brake cables are absent from this kit, so arrange cables that suit the park brake shoe assembly before use.
What’s included
This kit contains the monoblock caliper, the two-piece rotor with stainless hardware, the backing plate and park brake shoe assembly, plus stainless steel hoses with their hardware.
Not included: Your front rotor, lug nuts and park brake cables need to come from elsewhere.
