Overview
The Baer Brakes 72953-220 is a rear brake rotor set sold as a pair, with a slot-only friction surface and zinc-plated finish. It fits the 2018–2025 Jeep Wrangler JL and the 2018 Jeep Wrangler JK with a 342 mm rear rotor and the BR2 or BR6 brake code.
These are direct replacement rotors built as one-piece, full cast drum-in-hat units from cast iron. The slots give gas and dust a path out from between the pad and rotor during braking, which Baer links to a more consistent pedal feel and reduced brake fade. The zinc-plated face is aimed at owners running open center wheels, and the slot pattern is meant to match the slot/zinc only front rotors in the 6T Truck & OffRoad front brake kits.
Key features
- Slotted friction surface lets gas and dust escape from between the pad and rotor
- Premium grade, mill balanced direct replacement rotor
- Zinc-plated finish for a bright look behind open center wheels
- Rust resistant coating on a solid, one-piece full cast body
- Designed to complement the slot/zinc only front rotors in the 6T Truck & OffRoad front brake kits
Slotted rotor wear checks
Slotted rotors shed gas and dust from the pad face, but the slot edges also collect debris and can wear pads unevenly over time. During routine brake service, look at the slot walls and the outer friction edge for cracks, lipping or deep grooves. Surface glazing on pads often shows up alongside rotor wear, so inspect both together.
Brake fade and pulsing are usually tied to rotor thickness, pad material or uneven contact rather than the slots alone. Keep the directional marking aligned during installation and clean the hub face and mounting surface before fitting. Tighten lug nuts in a star pattern and recheck them after the first few drives.
- Check rotor thickness against the discard value for this rotor
- Replace pads when friction material wears near the indicator
- Clean rust from the hub face before mounting

Vehicle fitment
Manufacturer fitment covers the 2018 Jeep Wrangler (JK) and the 2018–2025 Jeep Wrangler (JL), applied to the rear axle. Match the rotor to a 342 mm rear brake rotor with the BR2 or BR6 brake code.
Among JK model years, it applies to 2018 only. It is a rear-axle part and not a front brake part. Confirm fit for your vehicle’s year, model and trim before ordering.
Installation notes
The brake surface is marked directional, so keep each rotor oriented as supplied. The ABS tone ring is not included, and brake lubricant is also left out of the set.
What’s included
A pair of direct replacement rear rotors, sold as a set.
Not included: ABS tone ring and brake lubricant.
