Overview
Hugger Orange is the caliper finish on this Baer Brakes Pro Plus front disc brake kit, part number 4301586HO, which uses 13 inch two-piece slotted, drilled and zinc plated rotors with a 6-piston caliper. The trucks it covers are 2WD 1/2 ton Chevrolet and GMC pickups from 1973 through 1988, and the kit is built to mount to DSE forged aluminum modular spindles, which are not in the box.
Rotors leave the factory assembled with NAS high grade stainless hardware. Mounting brackets and braided stainless hoses are part of the set. The design goal stated by Baer is wheels of 17 inch or larger. Because wheel fit cannot be guaranteed across styles, verify with the Q072H template before finalizing your wheel choice.
Key features
- Hugger Orange caliper color on a 6-piston 6P fixed caliper
- CNC machined caliper built from U.S. sourced forged or billet aluminum
- Stainless steel pistons and noise suppression clips
- Dual seals resist dust, weather and pressure
- Staggered pistons designed to reduce uneven pad wear
- Two-piece slotted, drilled and zinc plated rotor with a billet aluminum hat
Pad and hose maintenance
Brake pads wear at different rates depending on driving style, so inspect them regularly rather than waiting for a squeal. Look at the friction material for even thickness and check that the pad shims and clips move freely. Keep the caliper slide surfaces clean and lightly lubricated with grease suited to brake use. Brake dust builds up quickly on a new caliper, so wipe the area with brake cleaner rather than water.
Steel braided hoses last well when they are routed away from heat and sharp edges, but the outer braid can fray with age. Inspect them whenever the pads are changed or the system is opened. Replace any hose that shows cracks, bulges or chafing, and keep the mounting brackets tight so the hoses do not flap against the tire.
- Check pad thickness at every tire rotation
- Look for fraying on braided hoses
- Keep slides clean and free moving

Vehicle fitment
The GMC C15 and C15 Suburban are covered from 1975–1978, the GMC C15/C1500 and Suburban from 1973–1974, the GMC C1500 and Suburban from 1979–1986, and the R1500 with R1500 Suburban for 1987–1988. Chevrolet C10 and C10 Suburban are covered from 1973–1986, plus R10 and R10 Suburban for 1987–1988.
Model years outside 1973–1988, and the non-Suburban 1988 Chevrolet R10 and GMC R1500 trucks, fall outside this list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
A set of modular spindles must already be mounted, since this kit does not provide them. Run the Q072H template against your wheel before work starts. Once installed, test braking at low speed, because brake upgrades shift stopping behavior.
What’s included
Each rotor arrives assembled with NAS high grade stainless hardware. The package holds the 6-piston 6P caliper in Hugger Orange, the mounting brackets, stainless braided hoses with hardware, and two-piece rotors built for the D0731 pad type.
Not included: Spindles and wheels come from you; the package has neither.
