Overview
The Baer Brakes 6910048 is a left-side, 1-piece replacement rotor with a short hat and a slotted, drilled and zinc-plated surface. It measures 13.000 inch across and 1.100 inch thick, and Baer Brakes names it for certain Track4, SS4 and other Baer Brake systems.
A short hat is a shallower center section than a tall hat, and this rotor’s 1.717 inch overall height reflects that design. The vented, directional rotor uses curved vanes for cooling, is dynamically balanced and is built from cast iron. It is sold individually, so the opposite-side rotor is a separate part.
Key features
- Slotted, drilled and zinc-plated friction surface
- Short hat design with 1.717 inch overall height
- Curved vane venting for cooling
- Dynamically balanced for smooth operation
- Full cast, one-piece cast iron construction
- Performance grade with emission code 6
Short hat vs. tall hat
The hat is the raised center section that bolts to the hub. A short hat keeps the rotor closer to the hub face, which changes how it lines up with the caliper and the wheel bearing assembly. Because of that, a short hat and a tall hat rotor are not interchangeable simply because the diameter and bolt pattern match.
Before installation, confirm that the hub, caliper bracket and wheel offset suit a short hat design. Clean the hub and the mounting face so the rotor sits flat. Slotted and drilled friction surfaces help shed gas and water, but they also wear the pads differently, so pad choice should match the rotor’s intended use.
Inspect the rotor at each brake service. Check for cracks radiating from the center, heavy scoring, and thickness loss at the friction edge. Replace the rotor if it cannot be resurfaced within its thickness limits.
- Confirm hub and caliper clearance before fitting
- Match pad compound to driving conditions
- Torque lug nuts evenly in a star pattern
- Inspect the hat face for cracks at every service

Vehicle fitment
Tall-hat and right-side rotors are not covered by this part. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Because the hat is short, this left-side rotor must not be swapped with a tall hat version without confirming the system. Check the directional orientation against the left hub before fitting. Brake parts are safety-critical, so a qualified technician should install and bed in the rotor.
What’s included
One left-side short hat replacement rotor, sold individually.
Not included: the right-side rotor and any pads, calipers or hardware needed for the brake system.
