Timbren TIM-R225337 BES Coated Front Brake Rotor
The Timbren TIM-R225337 is a severe-duty front brake rotor built for the 2021-2024 Cadillac Escalade, Chevrolet Suburban, and GMC Yukon, using OnyxBond coating to resist the heat and corrosion that cause warping and pedal pulsation under heavy towing and hauling loads.
Key Features
- R225337 uses an OnyxBond matte black coating rated to 932 degrees Fahrenheit, 67 percent higher heat threshold than typical zinc-coated rotors
- Fly-cut balanced for smooth, vibration-free stops under high-torque braking
- Corrosion-resistant coating protects cooling vanes from road salt and moisture
- Direct-fit replacement for the factory front rotor

FAQ
What is the R225337?It is a Timbren BES coated severe-duty front brake rotor for the 2021-2024 Cadillac Escalade, Chevrolet Suburban, and GMC Yukon.
What does the OnyxBond coating do?It provides a heat- and corrosion-resistant barrier rated to 932 degrees Fahrenheit, which is about 67 percent higher than typical zinc-coated rotors.
Is this rotor for the front or rear?Front position only.
Why do standard rotors fail under towing?Thermal stress from heavy loads can cause warping and pedal pulsation, which this rotor's coating and construction are designed to resist.
Does this rotor require special break-in?Follow a standard gradual bedding procedure for new rotors and pads before normal driving.
Is this rotor fly-cut balanced?Yes, each rotor is fly-cut balanced to reduce vibration and shudder during high-torque stops.
Does this rotor fit rear applications on these trucks?No, this listing is for the front position only.
Will this rotor resist road salt exposure?Yes, the OnyxBond coating is designed to protect the rotor and cooling vanes from road salt and moisture.
Installation Instructions
- Raise and support the vehicle and remove the front wheel.
- Remove the caliper and caliper bracket following the applicable factory service procedure.
- Remove the factory or worn rotor from the hub.
- Install the new rotor and reinstall the caliper bracket and caliper, torquing hardware to factory specification.
- Bed in the new rotor and pads following a gradual break-in procedure before normal driving.
