Dynamic Friction 830-52010L Disc Brake Rotor - Rear Left

Overview

The Dynamic Friction 830-52010L is a rear left disc brake rotor built for select GM luxury and performance applications. It features a slotted and drilled surface, rust-resistant coating, and a Geospec Silver Grey hat finish for a clean, corrosion-conscious replacement.

Compatible With Buick LeSabre, Park Avenue, and Riviera; Cadillac DeVille, Eldorado, Seville, and Allante; Oldsmobile Aurora, Regency, and Toronado; and Pontiac Bonneville applications listed below. The 830-52010L is a fitment-specific rotor for vehicles that use a 5-lug, solid rear disc design.

Key Features

• Slotted X drilled braking surface for consistent pad contact and heat management.
• Rust-resistant coating helps protect exposed surfaces from corrosion.
• Plain disc finish with Geospec Silver Grey hat finish.
• Solid rotor construction with 5 bolt holes and 5 stud/lug holes.
• Directional braking surface for the specified rear left application.

Detailed Description

Dynamic Friction 830-52010L is engineered as a direct-fit rear left brake rotor for a range of Buick, Cadillac, Oldsmobile, and Pontiac models. Its 281 mm outside diameter, 70.7 mm center hole diameter, and 115/118 mm bolt circle dimensions support the specified applications, while the slotted and drilled face is intended for stable braking performance under repeated use. The 830-52010L also uses a rust-resistant coating to help preserve the rotor surface during service.

DFC Geoperformance Rotor - Drilled and Slotted refers to the product line used for this rotor. That line combines a performance-oriented surface design with corrosion protection and a clean hat finish, making it a practical choice for drivers replacing a worn rear brake rotor on a compatible Buick LeSabre, Cadillac DeVille, or Pontiac Bonneville.

What It Helps Address

• Brake pulsation from a worn or uneven rear rotor surface.
• Reduced braking consistency caused by heat buildup.
• Surface corrosion on an aging rear brake rotor.
• Noise or vibration related to rotor wear.
• Replacement needs for a damaged rear left disc brake rotor.

Installation Notes

Install only on the listed rear left applications. Verify rotor dimensions, bolt pattern, center bore, and directional surface orientation before installation. Match the rotor to the vehicle’s rear disc brake setup and confirm the notes for each fitment row, including the Oldsmobile Regency rear disc application.

Quality Assurance

Dynamic Friction supplies this rotor as part of its Geoperformance line, which combines drilled-and-slotted construction with a rust-resistant coating for service-focused brake replacement. Part number 830-52010L identifies the correct rotor for the listed applications, and 830-52010L is the reference to use when confirming fitment.
