Overview
The Baer Brakes 72953-020 is a rear brake rotor set, sold as a pair, with a slotted and cross-drilled friction surface and a zinc-plated finish. Its listed vehicles are the 2018–2025 Jeep Wrangler JL and the 2018 Jeep Wrangler JK, for applications with a 342 mm rear rotor and the BR2 or BR6 brake code.
Each rotor is a one-piece, full cast drum-in-hat design in cast iron, with slots and chamfered cross-drilled holes on the friction surface. The chamfered holes reduce stress cracking, while the slots let gas and dust escape from between the pad and rotor. The zinc-plated finish suits open center wheels, and the rotors carry a rust resistant coating.
Key features
- Slot and cross-drilled friction surface, giving gas and dust two escape paths
- Chamfered cross-drilled holes minimize stress cracking
- Premium grade, mill balanced rotor
- Zinc-plated finish for open center wheels
- Rust resistant coating
Pads and cross-drilled rotors
Cross-drilled holes and slots add extra edges to the friction surface, which can help clear gas and dust but also means new pads benefit from a careful bedding process. Use moderate stops for the first stretch of driving so the pad material transfers evenly. Avoid hard stops right after installation until the pads and rotors settle in.
Drilled holes can develop cracks under repeated heat cycles, so look for hairline lines around the holes at each brake service. Pad selection matters too, and a compound suited to the temperatures you expect often works better than a generic pad. Keep the zinc finish free of brake dust with regular cleaning.
- Inspect the holes for hairline cracks at each pad change
- Bed in new pads before aggressive use
- Choose a pad compound suited to your driving
