Overview
The Baer Brakes 31521-020 is a front set of Claw performance rotors for the 2008–2015 Toyota Land Cruiser and the 2008–2015 Lexus LX570, with the listed model years running 2008–2011 and 2013–2015. Each one-piece, full-cast rotor is a direct replacement with a cross-drilled and slotted friction surface, built so gases and dust can escape from between the pad and rotor during braking.
The slotted and cross-drilled face lets gases and dust escape from between the pad and rotor during braking. This design is built to support a more consistent pedal feel and reduced brake fade. The zinc-plated finish shows behind open-center wheels. The enhanced vane structure is designed for cooling and durability. The cast iron rotors are sold as a pair in one set.
Key features
- Cross-drilled and slotted friction surface that vents gases and dust away from the pad interface
- Enhanced vane structure for cooling, with premium materials for durability
- Chamfered cross-drilled holes intended to minimize stress cracking
- Zinc-plated finish that stays visible behind open-center wheels
- Premium, mill-balanced, direct replacement rotor
- Vented, directional brake surface with one-piece full-cast construction
Before you mount
Vented rotors move heat out of the friction ring as they turn, which is why the cooling passages matter on a heavy vehicle that stops often. Cross-drilled and slotted faces help clear pad material and moisture, but they also wear pads faster, so pad choice should match how the vehicle is driven. Bed in new pads and rotors with a series of moderate stops before any hard braking so the friction layer transfers evenly.
Good rotor work starts with a clean hub. Remove rust and debris from the mounting face, check the wheel studs, and tighten the wheel nuts in a star pattern. Re-check the nuts after the first few drives, since new rotors can settle slightly against the hub.
- Inspect rotor faces for deep grooves or heat cracks at each pad change
- Replace rotors that have worn below the minimum thickness cast into the hat
- Check the existing ABS ring on the hub before assembly
- Measure runout with a dial indicator if pulsation appears after installation

Vehicle fitment
It fits the front axle of these vehicles:
- 2008–2011 and 2013–2015 Lexus LX570
- 2008–2011 and 2013–2015 Toyota Land Cruiser
The 2012 model year is not in the manufacturer list for either vehicle, and rear-axle rotors are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The brake surface is directional, so confirm the intended rotation for each side before mounting. The ABS tone ring is not included, so the vehicle’s existing ring stays in use.
What’s included
A pair of direct replacement front rotors, sold as a set.
Not included: Brake pads and other hub hardware must be bought separately.
