Overview
The Baer Brakes 6910300 is a left-side, two-piece slotted, drilled and zinc-plated replacement brake rotor ring. It measures 13.150 inch in outside diameter and 1.250 inch in nominal thickness, and it is built for select Baer Brake systems. No make, model or year is listed with the part.
This vented cast iron ring is a two-piece design, as the specifications state. It has 12 mounting bolt holes on a 7.625 inch bolt circle. The rotor is directional, so the left-side version belongs only on the left hub of the vehicle, and the matching right-side ring is not included.
Key features
- Two-piece construction for this replacement ring.
- Slotted, drilled and zinc-plated surface.
- Curved vane design that is intended to aid cooling.
- Dynamic balanced for smooth, low-vibration running.
- Directional brake surface for the left side only.
- Castings made from premium materials, per the maker, with a design aimed at stability and resistance to distortion.
Inspecting and mounting rotors
A brake rotor works with the pads and caliper to slow the wheel through friction. Over time the friction surface wears, and repeated heating can cause cracks, scoring or uneven thickness. Vented rotors like this one have internal vanes that move air between the two faces, which helps the surface shed heat during repeated stops. Drilled and slotted surfaces are often chosen for braking feel and to help clear debris and gas from the pad face, although they can wear pads faster on some setups.
Rotor and pad choice go together. A pad that is too aggressive or too soft for the rotor can lead to glazing, noise or uneven wear. Hub condition matters as well, since a worn or corroded hub face can cause pulsation even with a good rotor. Check the mounting surface and runout before installing, and bed in new pads and rotors gently so the friction layers transfer evenly.
- Check the friction surface for deep grooves, cracks or a raised lip at the outer edge
- Replace pads at the same time when rotors are changed
- Inspect the hat and hardware for wear before mounting
- Clean the hub face and remove any rust before fitting
- Tighten lug nuts in a star pattern to the vehicle’s specification
