Beck Arnley 083-3705 Disc Brake Rotor - Rear

Overview of Beck Arnley Disc Brake Rotor 083-3705

The Beck Arnley 083-3705 disc brake rotor is engineered for reliable braking performance on Land Rover vehicles. Designed specifically for models like the Defender 90, Defender 110, Defender 130, Discovery, Range Rover, and Range Rover Sport, this rotor meets precise fitment requirements to ensure proper installation and function.

• Vented rotor design for improved heat dissipation
• 5-lug bolt pattern with 120 mm spacing
• Rotor outer diameter of 365 mm and thickness of 25 mm
• Center hole diameter of 79 mm for accurate hub fitment
• Minimum rotor thickness of 22 mm to maintain safety standards

Technical Specifications and Features

This vented disc brake rotor features a 5-lug configuration with a 120 mm bolt pattern, compatible with Land Rover models including the Defender 90, Defender 110, Defender 130, Discovery, Range Rover, and Range Rover Sport. The rotor has a 365 mm outer diameter and a surface thickness of 25 mm, providing a robust braking surface. The rotor hub outer diameter measures 201 mm, and the rotor height is 49 mm, ensuring proper clearance and fitment. The lug stud hole inner diameter is 14.5 mm, designed to accommodate standard lug nuts securely. The rotor center hole diameter of 79 mm allows for precise alignment on the vehicle hub. This rotor is vented, which helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use.

Application and Problem Solving

This Beck Arnley disc brake rotor 083-3705 is intended for use on Land Rover vehicles requiring a 5-lug, 120 mm bolt pattern rotor. It addresses several common braking issues:

• Uneven brake pad wear due to rotor warping
• Overheating and brake fade from insufficient heat dissipation
• Vibration or pulsation during braking caused by rotor thickness variation
• Corrosion or surface damage affecting braking efficiency
• Noise and reduced stopping power from worn or damaged rotors

Installation Notes and Tips

When installing the Beck Arnley 083-3705 rotor, ensure the vehicle is securely lifted and the wheel is removed. Clean the hub surface to remove rust or debris before mounting the rotor. Verify the rotor’s minimum thickness of 22 mm is maintained; replace if below this specification. Use proper torque specifications for lug nuts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance and rotor longevity.

Quality Assurance and Warranty

Beck Arnley disc brake rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The 083-3705 rotor undergoes rigorous quality control to ensure durability and consistent braking performance. This part includes a limited warranty against defects in materials and workmanship, providing confidence in its reliability for Land Rover Defender and Range Rover models.
