Overview
The Baer Brakes Pro Plus brake kit, part number 4301570GB, is a Grabber Blue front disc brake system for 1960–1986 Chevrolet C10 and GMC 2WD trucks. It uses a six-piston fixed caliper with a 14 inch two-piece rotor, and the rotor is designed to fit most wheels 18 inch or larger.
Baer Brakes builds the kit in Phoenix, Arizona. The calipers are CNC-machined from US-sourced forged or billet aluminum, and the Grabber Blue powder-coated finish is applied to the caliper for owners running Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles.
Key features
- Fixed six-piston caliper in a two-piece layout with Grabber Blue powder coating
- Pistons set in a staggered arrangement to reduce uneven pad wear
- Stainless steel is used for the pistons, abutments and noise suppression clips
- Dual seals for dust, weather and pressure
- Two-piece slotted, drilled, zinc-plated rotor with billet aluminum hat
- Uses the D0731 pad type; steel braided hoses carry DOT approval
Before you install
A front disc brake upgrade changes more than stopping force at the wheel. Fixed multi-piston calipers clamp the rotor with more even pressure than a stock single-piston arrangement, which helps pedal feel stay consistent under repeated stops. The rotor, pads and caliper work as one system, so matching the pad type to the caliper and rotor matters as much as the caliper itself.
Because this kit is built around aftermarket spindles, the spindles, hubs and bearings should be inspected before installation. Brake lines and the master cylinder are often reviewed at the same time, since a larger caliper can demand more fluid travel. When the truck is lifted or runs a larger tire, check hose routing for clearance at full steering lock.
- Inspect pads and rotor surfaces for uneven wear at regular intervals
- Check hose clearance after any wheel or tire change
- Re-torque caliper and rotor hardware after the first few drives
- Watch for pulsing, pulling or a soft pedal as signs of trouble

Installation notes
The spindles are not supplied, so Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles need to be installed on the truck first. Run template Q117P against the wheel you intend to use, because Baer cannot guarantee fit into every wheel style.
What’s included
Included are the six-piston calipers, two-piece rotors pre-assembled with NAS high grade stainless hardware, all mounting brackets, and steel braided hoses with hardware.
Not included: Spindles. The kit is built for Wilwood C10 Aluminum Modular Pro or Cpp X10 spindles, which must be provided separately.
