Overview
The Baer Brakes 6910078 is a left-side, 1-piece tall hat replacement rotor with a slot drilled and zinc-plated finish. It is a vented cast iron rotor with a 13 inch outside diameter and a 5 x 4.5 inch bolt pattern, sold individually for certain Baer Track4, SS4 and other Baer Brake systems.
The rotor is directional, so it is made for the left side of the vehicle only. Its full cast, one-piece build and slotted, drilled surface are paired with a curved vane design and dynamic balancing for smoother running.
Key features
- Slotted, drilled and zinc-plated surface
- Curved vane design for optimum cooling
- Designed for rotor stability and resistance against distortion
- Dynamic balanced for vibration-free performance
- Directional surface built for the left side
- Performance grade, full cast construction
Before you buy
A replacement rotor works as one part of a larger braking system. Its friction surface meets the brake pads, so pad compound, caliper condition and hub cleanliness all affect how the rotor performs once installed. Before fitting, wipe the hub face clean and confirm the rotor sits flat against it without rust or debris holding it off.
Tall hat rotors are often chosen for applications that need extra clearance between the hub and the braking surface. Because the hat height changes how the rotor seats, keep the left and right versions separate and confirm the orientation before tightening anything. Directional rotors also need to rotate in the intended direction, so a mix-up can reduce cooling and cause noise.
Rotors wear over time. Look for deep scoring, a lip forming at the outer edge, bluish discoloration from overheating, or a pulsing pedal during braking. A rotor that measures below its minimum thickness should be replaced, and pads are usually changed at the same service so the new friction surface beds in evenly.
- Measure runout and thickness before installation
- Replace pads at the same service when practical
- Bed in the new rotor and pads gradually
- Keep left and right rotors matched to their sides

Vehicle fitment
It is used with certain Baer Track4, SS4 and other Baer Brake systems. Match its 13 inch diameter and 5 x 4.5 inch bolt pattern to your Baer system before ordering.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Fit this rotor only to the left-side hub, since the directional surface is made for that side. Brake parts are safety-critical, so have a qualified technician install it and test the brakes before driving.
What’s included
One left-side replacement rotor, sold individually.
Not included: ABS tone ring.
