Overview
Baer Brakes Claw front rotors, part number 53040-020, fit 2007-2018 Jeep Wrangler JK trucks built without heavy duty brakes. The set covers the front axle only.
The rotor is a conventional, floating, one-piece full cast iron design with a zinc-plated finish and a straight vent layout. Its outside diameter is 11.89, nominal thickness 1.1 and discard thickness 1.04, and the set carries a limited 1 year warranty.
Key features
- Cross-drilled and slotted front face for gas and dust release during braking
- Floating rotor design for the front hub
- Chamfered cross-drilled holes, which Baer says limit stress cracking
- The rotor has a rust resistant coating.
- Five-hole, five-stud mounting pattern
- Premium grade with a straight vent design
Pads and hardware to check
Floating rotors sit on a hub carrier that lets them move slightly with the pad, so the carrier and its pins need to move freely. A stuck slide pin can drag the pad onto one side and wear the rotor unevenly, even when the new rotor is fine.
Pads should be matched to the rotor type and to how the Jeep is used. Lighter pads suit daily driving, while heavier-duty pads are better for off-road trips where brakes run hot on long descents.
Inspect the caliper bracket bolts, brake hose and hub bearings while the wheels are off. Any play in the bearing will cause vibration that is easy to mistake for rotor warp.
- Clean the hub face before mounting the rotor
- Lubricate the caliper slide pins with a brake-rated grease
- Bed in new pads with several moderate stops before hard braking
