Overview
The Baer Brakes 4302298GB is a rear disc brake kit that uses an S4 4-piston caliper in Grabber Blue with a floating caliper design. It pairs a 12 inch slotted, drilled, zinc plated rotor with a backing plate, and it is built for a rear axle with a GM 10/12 bolt C-clip small car pattern flange and a 5×4.75/5×5.00 wheel bolt pattern.
The rotor is a vented, 1-piece design. The backing plate that anchors the caliper also carries a 1-piece park brake shoe assembly. The caliper is 2-piece, machined from US sourced forged or billet aluminum, with hard anodized aluminum pistons and dual dust, weather and pressure seals. Steel braided hoses are included. Compatible pads are DR1 or HB100, with DR1-C as the FMSI number.
Fit into every wheel style is not guaranteed, so compare the S113E template with the wheel you intend to use. The SS4 suits most 16 inch or larger wheels, with a minimum wheel diameter of 16.0 inch.
Key features
- S4 4-piston caliper in Grabber Blue with a powder coated finish
- Floating caliper type with dual dust, weather and pressure seals
- 12.0 inch vented, 1-piece slotted, drilled, zinc plated rotor
- Park brake shoe assembly housed in the backing plate
- Stainless steel abutments and noise suppression clips
- Steel braided hoses, DOT approved
Before you install
A floating caliper slides on guide pins so the inboard and outboard pads both press the rotor. Because of this, the pins, bushings and boots need to move freely. Clean and lubricate the slide points as directed for your installation, and make sure the caliper is not binding before the wheel goes on. Rotor and pad replacement is often done together, so check the hub surface and rotor face for runout and rust during the job.
Park brake hardware is the part of a rear kit most often overlooked. Shoes adjust with wear, and the cables stretch and corrode over time, so inspect them when the rear brakes are opened up. Bleed the hydraulic system after hose replacement and bed in new pads gradually before heavy use. Keep brake fluid in a sealed container and replace it on the interval recommended for your vehicle.
- Inspect the slide pins and boots at every pad change
- Check rotor surface for cracks, scoring and minimum thickness
- Replace park brake cables if the parking brake no longer holds

Vehicle fitment
Fit is defined by the axle flange and wheel bolt pattern: GM 10/12 bolt C-clip small car pattern and 5×4.75/5×5.00. Confirm fit for your vehicle’s year, model and trim before ordering.
A bearing-on-axle flange is a different style from the C-clip flange used here, so match the flange type exactly.
Installation notes
The park brake shoe assembly is included, but park brake cables are not, so cables must be supplied separately. Use the S113E template to check wheel clearance before fitting the caliper. Test pedal feel and park brake hold on level ground before driving.
What’s included
Included: S4 4-piston caliper kit, 12 inch 1-piece rotor, backing plate with park brake shoe assembly, and steel braided hoses.
