Overview
The Baer Brakes 4301562R is a Classic Series front brake kit in red, built for GM G-body, S-10 and S-15 vehicles from 1978 to 2003. It uses two-piston aluminum calipers, one-piece integral-hub rotors measuring 11 inches, and modified stock height spindles, so the front end is a complete package rather than a set of loose parts.
The kit is designed for select 15-inch-plus wheels and tuned around a 15/16-inch master cylinder and a proper pedal ratio for correct line pressure. Manual setups can use a 7/8-inch master to reduce pedal effort, while bores larger than 15/16 inch require too much input.
Key features
- Aluminum two-piston, pad-guided floating caliper.
- Red powder-coated caliper with a black Baer logo.
- One-piece 11-inch vented rotor with integral hub, slotted, drilled and zinc plated.
- Stainless braided brake hoses for the front circuit.
- Uses the common FMSI D0412 ceramic brake pad.
- Bearings come with races pre-installed, and dust caps are included.
Master cylinder and pedal feel
Brake feel on an older GM car depends heavily on the master cylinder and the pedal ratio. A kit with larger rotors and calipers changes how much fluid the system needs to move, so the master bore and pedal ratio have to suit the new hardware for the pedal to feel right.
Power brake and manual brake setups behave differently. A manual system generally needs more pedal effort than a power system, and an incorrect bore can make a manual pedal either too hard or too soft. Confirm the master cylinder and booster arrangement on the specific car before the first drive.
After any brake work on a G-body or S-10, bleed the lines fully and check for a firm pedal at rest and under light braking. A spongy pedal usually means air in the system or a fitting that needs attention.
- Confirm the master cylinder bore before installing
- Check whether the car has power or manual brakes
- Bleed the lines completely after installation
- Test pedal firmness before driving

Installation notes
The included modified stock height spindles replace the factory spindles, and the bearings arrive with races already installed. Master cylinder bore matters here: the kit is tuned for a 15/16-inch master, while a 7/8-inch master can lower pedal effort on manual brakes. Use the D200A template to check clearance on 15-inch-plus wheels.
What’s included
The kit contains the red two-piston calipers, 11-inch integral-hub rotors, modified stock height spindles, bearings with races, dust caps, mounting brackets, stainless braided hoses and all hardware.
Not included: ABS tone ring.
