Overview
The Baer Brakes 4301570R is a red front Pro Plus brake kit for 1960–1986 Chevrolet C10 trucks, with listed GMC C15, C1500 and 3000 models and Suburban applications. Its 6-piston caliper and 14-inch rotor are sized for 2WD half-ton trucks that use 5×5.00 wheel bolt patterns and wheels of 18 inches or larger.
Baer’s design uses a 2-piece fixed 6-piston caliper clamping a 2-piece slotted, drilled rotor, with D0731 brake pads. Spindle compatibility is limited to Wilwood C10 Aluminum Modular Pro and Cpp X10 spindles, and the kit does not come with spindles.
Key features
- Red powder-coated fixed caliper with 6 pistons, built as a 2-piece design.
- Stainless steel pistons, abutments and noise suppression clips.
- Staggered pistons aimed at minimizing uneven pad wear.
- Dual seals for dust, weather and brake pressure.
- 2-piece slotted, drilled, zinc-plated rotor on a billet aluminum hat.
- CNC machined calipers from US-sourced forged or billet aluminum, made in Phoenix, Arizona.
- Stainless braided hoses with DOT approval, plus mounting brackets and hardware.
Pedal feel and fluid
A big-caliper front brake changes how the pedal feels, and the change is most noticeable on the first stops after a swap. Six pistons clamp more evenly than a single-piston setup, but they also need more fluid travel. Flushing the fluid on a regular schedule keeps its boiling point steady, which matters on long grades and when towing a trailer with a classic half-ton.
Before installation, check the master cylinder bore and the brake lines, since a new front kit can change pedal ratio and how the booster responds. Use fresh brake fluid when bleeding the system, and bleed the calipers in the correct order to avoid trapped air.
- Bleed the calipers in the order given in the shop manual
- Replace the fluid on a regular schedule
- Test the pedal in a safe area before driving on public roads

The manufacturer list covers the 1960–1986 Chevrolet C10, the 1967–1986 C10 Suburban, the 1960–1966 and 1987–1989 Chevrolet Suburban, the 1960–1966 GMC 3000, the 1975–1978 GMC C15, the 1967–1974 GMC C15/C1500, and the 1979–1986 GMC C1500.
Trucks from 1990 onward and 1987–1989 C10 pickups are not covered; for 1987–1989, only Suburban models are included. The kit is for 2WD, so 4×4 trucks are not covered. Confirm fit for your vehicle’s year, model and trim before ordering.
Installation notes
Because the spindles are separate, mount this kit only on a front end already fitted with Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles. Template Q117P is the reference for checking wheel clearance before assembly. A shop familiar with hydraulic brake service should do the installation.
What’s included
Red 6-piston calipers, 2-piece rotors with pre-assembled NAS high grade stainless hardware, mounting brackets, and stainless braided hoses with hardware.
Not included: spindles, which must be Wilwood C10 Aluminum Modular Pro or Cpp X10.
