Overview
The Baer Brakes 4401001CY is a Pro Plus front brake system in Comp Yellow, made for the 2007–2017 Jeep Wrangler JK when it still runs factory spindles and hubs. Its six-piston caliper clamps a 14-inch two-piece rotor, and the two are supplied together as a kit.
The caliper is built in Phoenix, Arizona, and the billet and forged aluminum parts are CNC machined in the US. Comp Yellow is a powder coated finish, and the pads use the D0731 friction type. Baer rates the system for wheels of 18 inches or larger.
Key features
- Six-piston fixed caliper finished in powder coated Comp Yellow
- Two-piece slotted, drilled and zinc-plated 14-inch rotor with billet aluminum hat
- Stainless steel pistons, abutments and noise suppression clips
- Staggered pistons for more even pad wear
- Dual seals keep out dust and weather and hold pressure
- Rotors come pre-assembled with NAS high grade stainless hardware
Bleeding and fluid service
A new front brake kit often requires the hydraulic system to be bled, especially after the caliper is removed or a hose is replaced. Air trapped in the lines makes the pedal feel spongy and reduces braking response. Bleed the caliper farthest from the master cylinder first and work toward the closest one, keeping the reservoir topped up so air is not drawn back in.
Fluid should be replaced on a schedule rather than only when a problem appears. Old fluid picks up moisture, which lowers its boiling point and can contribute to fade on a hard stop. Use fresh fluid of the grade your vehicle requires and avoid mixing fluid types. Dispose of old fluid properly.
- Bleed the farthest caliper first
- Keep the reservoir topped up during bleeding
- Use fresh fluid of the required grade
- Avoid mixing fluid types

Installation notes
Because the rotors are pre-assembled and the brackets and hardware come with the kit, this is a bolt-on front job on vehicles with OE spindles and hubs. Test the Q085P template against your intended wheel, since Baer does not guarantee wheel fit for every style.

Not included: brake hoses. The OE spindles and hubs are also not part of the kit.
