Overview
The Baer Brakes 6910339 is a left-side, one-piece tall hat replacement brake rotor with a slot-only surface and a 13-inch outside diameter. It is made for select Baer Brake systems and is sold as each.
The full cast rotor is directional and built for one side of the vehicle. Its 2.781-inch center hole and 2.232-inch overall height are part of the listed specification, along with a 4-stud pattern on a 108 mm bolt circle. This part number has no vehicle fitment listed.
Key features
- Full cast, one-piece build with a tall hat design.
- Slot-only braking surface on a vented rotor.
- Curved vanes are cast in to support cooling.
- Dynamic balancing intended to reduce vibration.
- Cast iron material with a Performance grade type.
Slot-only surfaces in use
Slots on the friction face give pads a path to clear dust, water and gas as they wear, which helps keep contact steady in wet conditions. The slots also leave less material between grooves than a plain face, so pads that run hard or develop a glaze can cause visible grooving over time. Matching the pad compound to the rotor’s intended use helps the pair wear together.
Because this is a tall hat design, the hub register and bolt seat should be checked before fitting. Look at the slots for cracking or lipping at each service, and clean away any rust that has built up on the hat. Replace the tone ring if your vehicle’s ABS setup needs one, since a missing ring can trigger a warning.
- Inspect slot edges for cracks at each brake service
- Clean the hub and bolt seats before mounting
- Bed in new pads with a few moderate stops
