Detailed Description

ATE SP25176 is a front brake rotor for 1999-2004 Land Rover Discovery applications. The rotor uses a vented design to help manage heat during braking, while the coated surface helps resist rust on exposed areas. Its full cast construction and non-directional finish support straightforward rotor replacement and a clean braking surface profile. This part cross-references Brembo 09.A229.11 for the same application.

Common Issues This Rotor Can Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Corrosion on the rotor hat and non-friction areas
• Reduced braking consistency from heat-stressed front rotors
• Noise or vibration associated with rotor wear
• Service replacement for a front Land Rover Discovery brake rotor

Installation Notes and Tips

Confirm rotor dimensions, bolt pattern, and front axle fitment before installation. Clean the friction surfaces before use and inspect pads, calipers, and hub condition at the same time. For 1999-2004 Land Rover Discovery front brake service, verify that the replacement rotor matches the original vented configuration and thickness specification. Part number SP25176 should be matched to the vehicle by year, model, and position before ordering.
