Overview
The Baer Brakes 6910342 is a one-piece, full cast replacement rotor, 13 inches in outside diameter, with a slotted, drilled and zinc-plated braking surface. It is made for the left side of select Baer Brake systems and has a tall hat with four studs on a 108 mm bolt circle. The rotor is directional, so it should only be installed on the axle side it is made for.
The castings use a curved vane pattern for cooling, and the rotor is dynamically balanced to run smoothly. The design is stability-focused and resists distortion. Rotors are supplied individually, so a left and right pair means two separate purchases.
Key features
- One-piece full cast construction with a tall hat
- Slotted, drilled and zinc-plated braking surface
- Zinc-plated finish for corrosion resistance as the surface is described
- Vented design with curved vanes for cooling
- Directional braking surface for left-side installation
- Dynamically balanced for vibration-free running
- 2.781 inch center hole that serves as the hub register
Choosing the right setup
A one-piece full cast rotor carries its hat and friction ring together, so the hub and caliper bracket must be checked as a complete assembly. The tall hat adds clearance needs that a shorter rotor would not, so look at caliper and wheel clearance before committing to a purchase. Drilled and slotted faces help shed gas and debris, but they also wear pads differently than plain faces, so choose pads with that in mind.
Zinc plating protects the hat and surface from surface rust while the vehicle is parked, though it does not replace regular inspection. Check the friction surface for heat cracks, deep scoring and uneven wear, and remove any rust ridge from the hub before fitting. Replacing both sides together keeps braking balanced across the axle.
- Measure hub clearance before fitting a tall hat
- Inspect the drilled holes for cracks
- Replace pads that have worn unevenly

Vehicle fitment
It is made for select Baer Brake systems. Match the 13-inch diameter, 4 x 108 mm bolt pattern and 2.781-inch center hole to your hub, and confirm fit for your vehicle’s year, model and trim before ordering.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The 2.781-inch center hole is the hub register, so measure the hub before fitting the rotor. Because the rotor is directional, confirm the axle side matches the position it will occupy. Brake work should be carried out by a qualified technician, and pads need proper bedding before normal use.
What’s included
One left-side, one-piece rotor with a slotted, drilled and zinc-plated surface, supplied as each.
Not included: the right-side rotor, which is supplied separately.
