Overview
The Baer Brakes 31294-020 is a rear performance brake rotor set, sold as a pair, for the 2001-2007 Toyota Sequoia, 2003-2009 Toyota 4Runner, 2007-2009 Toyota FJ Cruiser and 2003-2009 Lexus GX470. It is a one-piece, cross-drilled and slotted vented rotor for the rear axle.
Baer presents this rear rotor as a way to improve braking feel and appearance on these trucks and SUVs. Its slots and drilled holes let gases and dust escape from the friction zone, which Baer says supports steady pedal feel and less fade under hard use. The zinc-plated face suits owners who run open-center wheels and want the rotor to stand out.
Key features
- Cross-drilled and slotted rear friction surface that lets gases and dust escape
- Vane design and premium materials that Baer says help cooling and durability
- Chamfered cross-drilled holes intended to minimize stress cracking
- Mill balanced direct replacement rotor with a directional brake surface
- Zinc-plated finish for open-center wheels
Rear brake service
Rear rotors on these trucks and SUVs share the job of slowing the vehicle with the front discs, and they carry more load when the vehicle is heavy or pulling a trailer. Some vehicles also use the rear brakes for the parking brake, so the rear hardware should be checked for free movement after the new rotor is installed.
Rear rotors usually wear more slowly than fronts on road driving, but off-road use, muddy trails and frequent towing change that. Check for heat cracks around the drilled holes, uneven thickness that causes pulsing, and blue discoloration that shows overheating. Clean the hub face and remove rust scale before the rotor goes on so it sits flat.
- Check parking brake adjustment after fitting
- Inspect rear brake lines and hoses
- Replace rear pads when they reach minimum thickness
- Confirm rotor size before buying if the vehicle has a larger rear rotor

Vehicle fitment
This rear rotor set fits the 2001-2007 Toyota Sequoia (RWD and 4WD), 2003-2009 Toyota 4Runner (RWD and 4WD), 2007-2009 Toyota FJ Cruiser (RWD and 4WD) and 2003-2009 Lexus GX470 (4WD). The 4Runner and GX470 entries are for vehicles with the 12.3 inch rear rotor.
Front rotors are on a different axle and are not covered by this set. Model years outside the listed ranges are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Baer describes these as direct replacements for the rear axle. Because two of the listed applications note a 12.3 inch rear rotor, check your rear rotor size before ordering. Replace any rear rotor worn to the discard thickness of 16 or showing cracks.
What’s included
The kit is sold as a set and includes a pair of rear rotors.
Not included: brake pads, hardware and the ABS tone ring.
