Overview
Fire Red is the finish on the Baer Brakes 4302298FR, an SS4 rear brake kit for rear axles with a GM 10/12 bolt C-clip flange in the small car pattern. The kit uses an S4 four-piston floating caliper that clamps a 12 inch vented rotor with a slotted, drilled and zinc plated surface. The minimum wheel diameter is 16.0 inch.
The backing plate doubles as the caliper mount and holds a one-piece park brake shoe assembly. Braided brake hoses come with the kit and are DOT approved. The caliper is manufactured in Phoenix, AZ.
Key features
- Floating four-piston S4 caliper with dual pressure seals
- Pistons are hard anodized aluminum; abutments are stainless steel
- Dust, weather and pressure seals protect the caliper
- One-piece slotted, drilled and zinc plated rotor
- Park brake shoe assembly housed in the backing plate
- Supports the popular DR1 or HB100 pad types
Things to check before fitting
Before fitting any rear brake kit, measure the axle flange and confirm the wheel bolt pattern rather than relying on a model name. A C-clip flange is a distinct style from a bearing-on-axle flange, and a mismatch means parts will not seat. Confirm the vehicle’s year, model and trim before ordering, and keep the old parts on hand to compare.
A vented rotor moves air through internal vanes, which helps cooling on repeated stops. Check rotor thickness and surface condition against the minimum thickness marked on the rotor itself. Fit new hardware and clips with the pads, and make sure the caliper slides freely before the wheel goes back on.
- Compare the old flange and bolt pattern with the new parts
- Check rotor thickness against the minimum marked on it
- Replace worn caliper hardware and clips
- Test the brake pedal before driving

Vehicle fitment
Fitment is set by the rear flange, a GM 10/12 bolt C-clip small car pattern, and the 5×4.75/5×5.00 wheel bolt pattern. Compare your vehicle’s year, model and trim with the kit before ordering. Check the S113E template against your wheel to confirm clearance.
Axles with bearing-on-axle flanges do not match this C-clip design. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the park brake shoe assembly sits in the backing plate, the parking brake is replaced during the same installation. Park brake cables are not included, so verify that your cable routing matches the new assembly. Work should be done by a qualified technician with the vehicle supported on stands.
What’s included
The kit includes the S4 four-piston caliper, the 12 inch vented rotor, the backing plate with park brake shoe assembly, and braided brake hoses.
Not included: park brake cables.
