Overview
The Baer Brakes 6919627 is a 1-piece, left-side replacement brake rotor with a modified drum and drum lip, for use in select Baer Brake systems. Its vented cast iron body has a slotted, drilled and zinc-plated surface.
Measuring 12 in across and 1.02 in thick, with a 2.406 in overall height, the rotor is directional and made only for the left side. The listed register is 2.780 in, with a 2.78 in center hole.
Key features
- Modified drum and drum lip in the hat
- Slotted, drilled and zinc-plated friction surface
- Curved vane design for cooling
- Cast in one piece as a full cast construction
- Dynamically balanced for smoother running
- Designed for rotor stability and distortion resistance
Hat and hub fit
The hat is the part of the rotor that bolts to the hub, so it controls how the disc sits on the axle. A modified hat can change where the disc face lands, which affects runout and pedal feel. Before fitting a rotor with a non-standard hat, clean the hub face, remove rust and burrs from the register, and test-fit the rotor by hand so it seats fully without forcing.
Hub and register fit matters more than many buyers expect. A rotor that sits slightly off-center will wobble and cause vibration under braking, and a register that is too tight can keep the disc from sitting flat. Compare the center hole and register measurements with your hub before buying, and check runout with a dial indicator once the rotor is mounted.
Modified drums and lips are often used on older or specialty axles where space or hub design differs from a standard setup. Inspect the bearings, seals and hardware on the same axle, since a worn bearing will undo a good rotor. Keep the left-side rotor on its correct axle position and check pad clearance before the first drive.
- Clean the hub face and register before mounting
- Check runout with a dial indicator after installation
- Inspect bearings and seals on the same axle
