Overview
The Baer Brakes 05115-020 is a pair of front Claw performance rotors for 1990–1999 four-wheel-drive Jeep applications, including the Cherokee (XJ), Grand Cherokee (ZJ), Comanche, Grand Wagoneer (SJ), Wagoneer and Wrangler (YJ and TJ). These are conventional vented rotors in cast iron with a slotted and cross-drilled friction surface.
Gas and dust leave the pad interface through the slots and holes, which supports more consistent braking and less fade. Each rotor has a rust-resistant coating and a zinc-plated finish, and the holes are chamfered to limit stress cracking. Dimensions are given in inches with millimeter values in parentheses.
Key features
- Conventional vented rotor with a slotted and cross-drilled friction face
- Rust-resistant coating applied to each rotor
- Chamfered cross-drilled holes to minimize stress cracking
- Zinc-plated finish for a clean appearance
- Premium grade, one-piece full-cast construction
- Enhanced vane structure for cooling and durability
Care and inspection
Cast iron rotors rely on their friction faces and cooling vanes to shed heat, so keeping the face clean and free of oil or grease matters. Brake dust and light surface rust can be wiped away, but a rotor that has glazed or cracked near the holes should be replaced rather than resurfaced.
Older Jeep suspensions often have worn ball joints, bushings and wheel bearings. These can cause uneven pad contact and runout that look like a rotor fault, so inspect them before fitting new rotors. Use anti-seize sparingly on the hub face, keeping it off the mounting surface, and recheck lug torque after a short drive.
- Clean the hub face and rotor mounting surface
- Inspect wheel bearings for play

Vehicle fitment
It fits 1990–1999 Jeep Cherokee (XJ) with the 82mm tall rotor, 1990–1992 Jeep Comanche, 1993–1998 Jeep Grand Cherokee (ZJ), 1991 and 1993 Jeep Grand Wagoneer (SJ), 1990 Jeep Wagoneer, 1997–1999 Jeep Wrangler (TJ) and 1990–1995 Jeep Wrangler (YJ), all with 4WD drive.
Not covered: 2WD versions of these models, Cherokee without the 82mm tall rotor, Grand Wagoneer years other than 1991 and 1993, and Wrangler years outside the two ranges above, such as 1996. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Check the hub’s center diameter against the listed 72 (2.83) before fitting. For the Cherokee, measure the existing rotor’s overall height first, since that entry is tied to the 82mm tall rotor. Support the Jeep on stands and remove the wheel before starting brake work.
