Overview
The Baer Brakes Claw performance rotor set, part number 05570-020, is a pair of front brake rotors for 1988–1991 Chevrolet C1500 and GMC C1500 pickups with a standard cab, standard chassis and rear-wheel drive (2WD). They are direct replacement rotors that take the place of the factory front rotors on these trucks.
Each rotor has a cross-drilled and slotted friction surface. The slots and holes let gases and dust escape from between the pad and rotor during braking, supporting a more consistent pedal feel and reduced brake fade. The rotors are zinc-plated for a bright finish behind open center wheels.
Key features
- Cross-drilled and slotted friction surface that lets gases and dust escape from between the pad and rotor
- Enhanced vane structure and premium materials, which Baer cites for cooling and durability
- Mill balanced, direct replacement rotor design
- Chamfered cross-drilled holes intended to minimize stress cracking
- Zinc-plated finish for open center wheels
- Vented, one-piece full cast construction with a directional brake surface
Older truck brake care
Brakes on pickups from this era rely on simpler hydraulics, so the system depends on steady maintenance more than electronics. Fresh front rotors work best when the calipers slide freely, the brake hoses are sound and the master cylinder is not leaking. A rotor with a slotted face can run cooler under repeated stops, but it still needs good pad contact.
Old rubber lines and seals can hide problems that new rotors reveal, such as a soft pedal or uneven pad wear. Inspect the hoses, replace fluid that looks dark, and check the wheel bearings before the truck returns to regular service. Directional rotors should be installed with the face oriented for the side they are fitted to.
- Check caliper slide pins and bushings
- Replace brake fluid that looks dark or contaminated
- Inspect wheel bearings during rotor work

Vehicle fitment
The rotors fit front axles of 1988–1991 Chevrolet C1500 and GMC C1500 pickups with a standard cab, standard chassis and 2WD drive.
The list does not cover other Chevrolet or GMC generations, extended cab or crew cab trucks, four-wheel-drive versions, or other C-series and K-series models. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the brake surface is directional, mount each rotor with its drilled and slotted face oriented for the rotation direction marked for its side. Replace rotors in pairs so both front sides brake alike. Brake rotor work should be done by a qualified technician with the vehicle safely supported.
What’s included
The set includes a pair of direct replacement front rotors, one for each side.
Not included: Brake pads and other hardware are not part of this set.
