Overview
The Baer Brakes 05522-020 is a set of front Claw performance rotors for a long list of 1971–1991 Chevrolet, GMC and Jeep applications. The product is titled for various applications, and the rotors are direct replacements for the factory front discs on those vehicles.
The cross-drilled and slotted face lets gases and dust escape from between the pad and rotor during braking, which supports a steadier pedal and less fade. The rotors are one-piece cast with a zinc-plated, rust resistant finish.
Key features
- Slotted and drilled face relieves gases and dust at the pad interface.
- Vane structure designed for cooling and service life.
- Premium grade, mill balanced replacement rotor.
- Chamfered drilled holes meant to minimize stress cracking.
- Zinc-plated finish with rust resistant coating.
Choosing the right rotor
Older trucks and Jeeps often have rotors that have sat for years, so the hub face, bolt holes and caliper bracket should be checked before anything new goes on. Rust on the hub can stop a rotor from sitting flat and cause a wobble that feels like a pedal problem. Clean the hub with a wire brush and check for pitting before fitting.
Because these vehicles cover many model years and body styles, the pad and caliper setup may have changed over time. Check that the calipers and brackets on your truck match the setup you are fitting. Older braking systems often benefit from new hardware, brake hose inspection and fresh fluid at the same service, since those parts can age even when the rotors are new.
- Clean and inspect the hub face and studs
- Check caliper bracket condition and bolts
- Replace brake hoses that show cracking
- Bleed the system if the pedal feels soft after the job

Installation notes
Support the front axle on stands before removing the factory rotors. The six lugs sit on a 139.7 mm (5.5 in) bolt circle, and the 4.0 in (101.7 mm) center hole should be checked against the old rotor. Install both fronts together and replace any rotor worn to the 30.86 mm (1.21 in) discard thickness.
What’s included
A set of two front direct replacement rotors with a zinc-plated finish and rust resistant coating.
Not included: ABS tone ring.
