DuraGo BR5558 Disc Brake Rotor - Front
DuraGo BR5558 Front Vented Brake Rotor
The DuraGo BR5558 is a front disc brake rotor built from cast iron with a full cast construction for consistent braking performance. It is a conventional, vented rotor with a non-directional brake surface, making it a direct replacement option for select Chevrolet, Buick, Pontiac, Oldsmobile, and Cadillac applications.
Engineered by DuraGo, a brand with more than 45 years in aftermarket brake manufacturing, this rotor reflects the company’s focus on fit, form, and function. The BR5558 is a practical choice for drivers servicing front brake systems on vehicles such as the Chevrolet Cavalier, Pontiac Sunbird, and Buick Skylark.
Key Features
- Cast iron construction with full cast design
- Vented front disc brake rotor
- Non-directional brake surface for service flexibility
- Conventional rotor design, not drum-in-hat
- 5-bolt mounting pattern
- Outside diameter: 246 mm (9.69 in.)
- Center hole diameter: 58.4 mm (2.3 in.)
- Mounting bolt circle diameter: 100 mm (3.94 in.)
- Nominal thickness: 22.35 mm (0.88 in.)
- Discard thickness: 20.7 mm (0.81 in.)
Detailed Description
The DuraGo BR5558 front brake rotor is manufactured to meet the dimensional requirements needed for proper rotor fitment and brake system operation. Its vented design helps support heat dissipation during repeated stops, while the cast iron construction provides the mass and stability expected in a conventional replacement rotor. This part cross-references Monroe Shocks & Struts 5558 for the same application.
Compatible With front brake service on 1985-1991 Chevrolet Cavalier, 1987-1991 Chevrolet Corsica, 1986-1991 Pontiac Sunbird, 1990 Buick Skylark except Performance Package, 1990 Oldsmobile Cutlass Calais except Performance Package, 1990 Pontiac Grand Am except Performance Package, 1985-1989 Buick Skyhawk, 1986-1989 Buick Skylark, 1988-1989 Oldsmobile Cutlass Calais, 1985-1989 Pontiac Grand Am, 1985-1988 Cadillac Cimarron, 1985-1988 Oldsmobile Firenza, 1985-1987 Oldsmobile Calais, and 1985 Pontiac J2000 Sunbird. The BR5558 also cross-references DENSO Auto Parts 5061 for the same application.
What This Rotor Helps Address
- Brake pulsation caused by worn or out-of-spec front rotors
- Reduced braking consistency from heat-affected rotor surfaces
- Rotor replacement needs during front brake service
- Fitment requirements for 5-lug compact GM front brake systems
- Service on vehicles requiring a vented conventional rotor
Installation Notes and Tips
Verify rotor dimensions, bolt pattern, and hub fitment before installation. This rotor uses a non-directional brake surface and does not include an ABS tone ring. It is not cross-drilled or slotted, so it installs as a conventional replacement rotor for the listed front applications. Confirm whether your vehicle is equipped with the Performance Package, since some 1990 Buick, Oldsmobile, and Pontiac applications are excluded.
Quality Assurance
DuraGo manufactures brake products through ISO-certified factories and builds its brake drum and rotor program around fit, form, and function requirements. The BR5558 is produced to support consistent aftermarket replacement quality for the specified front brake applications.
